I was hoping for ballistics or something to show performance of 9mm v 5.7mm rounds. Honestly, this video has essentially convinced me that 5.7 has some good advantages and pros to consider, and can and will in fact compete with 9mm. Just because rounds are *presently* more costly for 5.7mm, doesn’t mean that 5.7mm will *never* compete with 9mm. All that is is supply and demand. And companies *are* making 5.7 weapons, increasing supply. The fact that this video is *even being made* is kind of proof 5.7 is already on the rise and has some legit upside. Companies *have begun* making 5.7 weapons! Just b/c *you don’t see it happening* doesn’t mean it won’t, in fact, *ever* happen. Silly. In fact, I’m gonna go grab me a PSA 5.7 Rock.

The 5.7x28 was developed to replace the 9mm as a war-fighting cartridge, not an urban commando, miniaturized tacticool handgun. FN designed the round to penetrate 20 layers of Kevlar bonded to 1.6mm thick Tungsten plate at 150 meters. The 9mm can't penetrate that even if the muzzle is held against it! To achieve this they went with a .224" bullet because of simple physics (OMG I know that will disturb the internet experts!). A .224" has much less cross-section and so achieves a higher penetration factor all other things being equal. This is why the .22LR punches well above it's paper ballistics. By using a steel penetrator core, 31 grain bullet the primary design goal was achieved. The purpose of a military round is to create wounds and produce casualties, not to "kill" as is almost always referenced by the blood-thirsty concealed carry crowd, and the longish bullet tumbles when passing through muscle and such and has a greater ability to shatter bone than does the 9mm (hence the higher pF). The Ft. Hood shooting condensed about a decade's worth of random street data into a single even that while terribly tragic, validated the lethality of the 5.7x28 round as fired from a pistol. Average "shots on target" was less than three, which means some were shot more than three times, and others just once. The final tally was 13 dead and 30 wounded, and even the MP who finally took out the shooter was hit in the thigh resulting in a shattered femur. Despite all the disinformation spewed on the internet, the 5.7 fired from a handgun easily surpasses the 9mm as a warfighting solution. Where it does NOT shine is being cut down to a sub-compact with short barrel which means the 9mm will retain that category by virtue of it's bottom-feeder status - being just 1/3rd more potent than the .380 ACP. The 9mm has benefitted from decades of bullet development to make it a better urban commando round, whereas the 5.7x28 has been purposefully denied such development to avoid being labeled a "cop killer" round and stamped out by the gun grabbers (which the 9mm FUDs would likely cheer because they're too stoopid to realize that once the grabbers have all the other calibers they'll come for theirs as well!) The 5.7x28 cartridge should be a fraction of the cost of 9mm but has been hampered by having been loaded in quantity by one company - FN, even under other names such as Fiocchi and American Eagle. Custom loaders have shown the potential of the round performance wise - such as being able to punch through a Kevlar helmet and the head inside, or penetrate three TL3A Kevlar vests, and still tumble on impact with gel. In large measure we can thank ammo hoarders who drove the price up from about $15/box 4 years ago to what it is today, and of course the ammo. Also the brass is proprietary so handloaders can't easy form their own without significant labor and until just recently all brass was head stamped "FNB" which has kept the price elevated.

As a gun dealer, I'd say it's about 50/50 right now. 5.7 is just now starting to gain popularity due to more and more manufactures making guns chambered in it. I've seen a good uptick of my customers wanting 5.7 pistols. Biggest factor holding it back still is ammo cost and availability. It's gotten a lot better in recent years but still a bit to much for the average shooter. Hopefully it gains more traction and it becomes cheap and plentiful.

A 5.7 with an optic is literally a pocket rifle.

5.7 used to never be stocked at my local pew pew shop now it’s got a whole shelf to it self it’s definitely growing in popularity and I’m seeing various gun companies come out with 5.7 models and so far smith and Wesson has the best one imo, I think we’re def going to see a rise in these firearms poping up

I'm not even American and I like this channel. Hey as I always say in gun channels, American friends, PLEASE protect your rights given by born or If you're man of faith, given by God. Keep the flame of liberty always bright!! By the way, greetings from Chile!!

I just bought a PSA 5.7 Rock. So far I’m well pleased with it. It definitely has a range advantage over 9mm. It’s highly accurate at range and accuracy equals deadly in book. I still have my 9mm and I intend to always have 9mm’s because of course ammo is cheap but my 5.7 is my go to edc from now on, especially in the woods.

Honestly if I didn't want 5.7 before I do now, great review.

The only reason I don’t have a 5.7 is the cost of ammo

If 5.7 was ever the same cost as 9mm it would absolutely be viable. Arguably one of the best calibers for a pistol/pcc combo with compatible mags.

getting more shots on target more accurately is more important than "ft-lbs of energy

The 5.7 was used in the shooting on Ft Hood military base in 2009 he injured 30 and killed 13. Its very capable of self-defense. Its high capacity, flat shooting, and high velocity. Also, it has the ability to peirce body armor with the right ammo.

Your argument is what 45 acp guys used to use against 9mm guys. Just saying…

5.7 is better than 9mm in every way, velocity, recoil, mag size, except price. The price alone makes 5.7 not a viable option. If the price was closer to 9 i would only carry 5.7.

5.7x28 was designed to supercede 9mm in nearly every way... and it does just that. There are a few reasons to choose 9mm over 5.7x28... 1- price 2- more firearms to choose from 3- better subsonic performance In short, if you're not shooting subsonic, and can find a 5.7x28 firearm you like within your budget... choose the 5.7x28.

5.7 is clearly directed to the wealthy gun enthusiasts. I can barely practice once a month with the cost of the cheapest 9mm, I know very little gun enthusiasts' friends who can afford this.

Smith and Wesson and Ruger Did a excellent job with the 5.7 X28 Ruger also has compatible mags that take in a carbine type rifle so price is minor I love my 5.7

Next we need a video why 9mm will never compete with 10mm

I would point out a missing advantage of 5.7 that was left out. The guns may be larger which makes carrying a little bit difficult, but the ammo is lighter which means carrying extra is easier. The main reason in past that 5.7 hasn't been widely adopted is the FN57 is overpriced. I can see law enforcement converting to 5.7 at the price of a PSA or M&P (even if I think the Ruger is the best of the group it's more expensive). I think overtaking 9mm isn't likely in the short term. Long term however every disadvantage that is mentioned here can change and be overcome. 5.7 seems like the caliber of the future.

The most important thing to consider about the 5.7 is the fact that for older people with wrist problems it is the best handgun to shoot. There is almost no recoil. Especially with the Smith & Wesson 5.7. It is one of the most accurate handguns with the lowest recoil possible, while keeping the power 🫣 Hate on the 5.7 all you want but I will choose it over a 9mm anyday.

My compact 9mm is my urban carry, but when I’m out in the desert riding or rockhounding I’m packing the rock 5.7, very accurate at 100yds plus.

Lots of negative comments from people who clearly have no knowledge on the 5.7. I’ve had one since FN launched it. Not an EDC for me, but who ever said self defense has to equal carry? It holds 21+ rounds without a ridiculous extended magazine, it is accurate as hell, very little recoil, ammo is compact, and getting much more available. Everyone I have ever let shoot it falls in love. It’s by far my wife’s favorite handgun, so I’ll spend the $50 a box every day of the week to know she has something she’s confident with. I have shot coyotes, badgers and prairie dogs at over 80 yds. I even had the unfortunate need to dispatch a moose (brain worm). Conservation officer didn’t want a brain shot, so I had to hit the heart. I carry 9mm and obviously have nothing against it, but there’s a 5.7 at my bedside.

Thanks for the vid! Love my 5.7 have the s&w as well! I bought it because of the roller delayed blowback, and it literally shoots softer than a 22lr. I put the holosun 407 on it and it’s a track driver!! I did have some mag issues early on but thats resolved and s&w is great to work with. Also i do appendix carry my 5.7 so it can be done also not a tall guy Im about 5’10/5’11. I did have to move it slightly from where I carry my shield but it carries smaller than it looks.

I just ordered a Ruger 5.7 carbine to rig out for home defense. With a good red dot set up for up to 50-100 yards and a laser set up for 15-25 yards it’s low recoil will allow for quick accurate follow up shots and with 2 loaded mags (40 rounds) it’s a great defense weapon in my opinion.

Unless you are a giant or open carry, 5.7 is simply out for defense as there are no compact or sub compact guns chambered in it. And for good reason, ballistics would just suck out of a 4‘ or smaller barrel

9mm is on borrowed time…5.7 smokes 9mm in everything except mass. I just bought a case of 5.7 for 43 cents a round. The AP rounds are devastating

Price and availability aside ... i would trade in my 9mm for a 5.7. Yes i would love to see more after market support for 5.7 , more availability and better prices... but there are so many pros to 5.7 , even now id still choose it over 9mm.

5.7 has: less recoil, more range, higher capacity.. it’s a pretty darn good round. I got mine because of novelty but now it’s a conceal carry contender.

Dude.. 5.7 is more than capable of being a dependency self defense round.

5.7 is slowly becoming more affordable. Not the cheep choice, but very nice in many regards. Low recoil and much higher FPS. I can’t buy one in my State yet, however we’re working on that. 😉

I carry a ruger 57 it is fast precise and powerful love it

FN America introduced in November, 2023 a new 5.7x28mm 30-grain self defense round and a new 40-grain training round to go along with their 5.7x28mm sport shooting and their small game hunting rounds.

If you are being shot at by someone over 50 yrd away or they are in a car you're going to wish you had that 5.7

5.7 as a *training tool* is very interesting. Would you have any guidance on how to use it training tool?

I preordered the m&p 5.7 and in between waiting I got the 22mag kel Tec pistol which I could see as a good way to train for 5.7; however, I still haven’t even shot my 5.7 because none of the ranges allow it.

9x19 aka 9mm parabellum was introduced 1909, it didn’t become a dominant force in the gun industry until 50 years after its introduction for militaries, and for the civilian market it didn’t become dominant until the lates 1980s/early 1990s. So 5.7 being 30 or so years old, it’s still a baby and by the time it reaches its 60th or 90th birthday it may indeed replace the 9mm.

57 ammo prices have dropped drastically in price now and continues to fall

I’m sorry, bro, the five sevens got body armor penetration. High compressed rounds like a 40. And low 45s. Just get soak up. And with armor being widely used now. I can’t justify not to have a 57. My wife carries a 365 XL. And she wishes her hands would fit the 5.7 due to the low recoil. In a high stress situation. And, blood pressure is up, heart rate high. The low recall, and the better grouping. The 5.7 is the answer.

I have this weapon and countless 9mm platforms, and I would take it over 9mm in 90% of scenarios. I bet I could place 5 VERY accurate shots with the M&P 57 whereas I could place 3 very accurate shots with my best handling 9mm. 5.7 had way less over penetration, which means more energy dumps into the target vs 9mm. Initial penetration is also better for high density fibers because of the velocity.

Remember the fort hood shooting? The shooter was using 5.7 and all the people died. He was shot multiple times with 9mm and lived. Nuff said!

5.7mm is very dependent on velocity just like 5.56mm so you have to stay with full size pistols to do that with 5.7mm.

I have the ruger 5-7 and sold my ruger American 9mm.. the ruger you will not miss in self defense. Plus it's incredibly clean firing round. Plus and I have fired over 3000 round with no jam ups.. Plus by design the rounds slide in very smoothly into the barrel. 9mm jam. The ruger 5-7 is set up like a 1911.. and incredibly accurate.. price has is not the object, but safety is ...

I think you are coming to a couple of wrong conclusions in your analysis. Due to the easier shooting experience of 5.7, I need way less range time to master it, than I need with a 9mm. This means I have way less ammo cost compared to 9. I buy a box of hollows for carrying and otherwise a box a month for training. Rounds are around .40$ right now. So this whole cost argument is not valid or in favor of 57. And for the rest, I carry my S&W 57 as it has a very low footprint means is flat and adapts to my body at IWB 3 o'clock. It's not printing and allows me due to the low profile slide to carry it in a belly holster. My Masada S and CANIK TP9SC Elite are much more uncomfortable to IWB than the 57. In general I disagree with you on this one .

Was this uploaded before the PSA Rock 57 and their AAC 5.7 ammo line?

The Fort Hood shooting was a FN FIVE SEVEN pistol. Everyone shot with that pistol and caliber was killed. So, yes it is more deadly compared to a 9mm.

35 years? Maybe..but it was only known to certain priveleged groups. The 5-7 came out to some commercial success but that was only a handful of yrs ago. I see ppl talking about velocity and baliatics but the 5-7 is uber fast and certain loads are known to penetrate kevlar (its def $$ but there are more options for 5-7 loads coming out now days and some are wiked)

1) The 9mm didn’t make an immediate impact in 1901. Here in the US/NATO, it didn’t make an impact until the 1970’s. That’s over 70 years that it took to take the 45 in the Military and the 38 in Law enforcement. 2) In 1989, NATO wanted a new side Arm round developed that worked a lot like the 5.56 but again for a sidearm. Something with range, something with power, and something with lite recoil. Also, ammo that could penetrate class 1-3 body armor. The 5.7 does all of that now with SS192 rounds. 3) it has been 30 plus years. The round has improved over that time and actually 2 years ago, NATO adopted the 5.7. It is probably going to take a long time but eventually the 5.7 will replace the 9mm. In My OPINION, I think that it is to accommodate woman in combat. Not that woman can’t fire a 9mm but 5.7 is better for small statured people. Again, My opinion. 3) The 5.7 is not really developed for expansion like a 357 or 9mm. It’s like a 5.56. It is a fragmented/tumbler round. It will enter a body with an initial small cavity but explode and ricochet off of bone and organs before it exits. In fact it may leave a bigger entrance hole than an exit and at times take huge chunks out of a body. By the time the bullet exits, it’s made organs and tissue into mush. Much like a 5.56 round. It’s not really designed as a good expander. 4) I think the round will come down in price but it will take a lot of time. 5.7 is probably the future but distant future.

I heard a box of 20 Liberty Civil Defense 9mm is 50$ and a box of 50 5.7 is 50$. I am no gun expert but regardless of the cost, I suggest buying at least 1 or 2 boxes. You get the power of the 9mm + somewhat the recoil, range and L3 Body Armor Piercing of the 5.7. The Liberty Civil Defense Ammo travels 2000 fps not as fast as the 5.7 at 2500 fps but both can stop L3 Body Armor. Also it has better accuracy over range but I dont think people will use them above 50 meters by then they should probably be using ARs LMGs or Snipers anyways.

My self defense ammo for 5 7 does 2600+fps with a 40gr green tip and that's around 600ftlbs and cost me $2 a round while tested penetration through 3a BA. In my 9mm's I used Underwood Extreme Penetrator 68g @ 1800fps, 490ftlbs and a $1.25-$1.50 a round. Aside from ammo cost and availability in a SHTF situation, the benefits of 5.7 mentioned in the video outweigh 9mm. To me, 5.7 is excellent in pistol or PDW type AR pistols and outshines my comparable 9mm firearms. Peace

I took my 5.7 out for the first time last week; I think I agree. Unless you count 200yd shots as self defense, 9mm is the way to go. I will keep my 5.7 around though 😄

Ruger makes a 5.7 Carbine and pistol FN created it and has a pistol and carbine Psa comes out with a pistol and carbine Federal starts making ammo for it Fiocci starts making ammo for it Then S&W makes a new pistol for it. All these companies start making stuff for this and you still don’t see it happening? Sorry man this whole video seems to be a love letter to the 9mm. Video gives me vibes of old timers from the 70/80s talking about how 9mm will never top the 357 .38 or 45acp.

5.7 is a better round than 9mm by a mile in any ballistic category wether shooting from a pistol or a carbine. 5.7 even defeats type 3 body armor from a pistol, it only falls short against 9mm in affordability do to the popularity of the 9mm. Also 5.7 pistols are limited to full size handguns and up, I don’t think they will ever be able to reach the subcompact and micro market do to the nature of the round itself

Was told by a former mercenary "double tap them with the 5.7 ... they don't get up!" .

Have you bought and tested the Palmetto State Armory: ROCK 5.7?? Might get better results

I have a question.. i live in Texas. when I was 19 I got in trouble and was told I could never own a firearm. Tried everything to fix it but..they say no. I am now 40 years old, don't do drugs, work 60 hours a week, never been in trouble since. Carry anyway? Just keep one at the house?

I like the 5.7X28. I agree that it will not replace the 9mm but there are more options coming now. I recently bought a Kel Tec P50 and fell in love with the round. I am now looking to buy a more typical handgun chambered in the 5.7. I am leaning toward the Rock Island. I also saw an AR 15 conversion kit to convert it to 5.7. The price of ammo is beginning to come down. I like the idea of having one round work in several platforms.

I know some people don’t like 5.7 but if they could get the barrel length down and keep the fps up it’d be great. P.s. smith should offer this without a threaded barrel

5.7 is not a home defense round, it's a rifle round. You need a round that will expand to 3 to 4 times it's size to produce enough stopping power. A rifle round will just go straight through you. I'm on the market for a S&W 5.7 with optics but only because I have an itch for the FN 5.7. it will never replace my glock27 for conceal carry. I may end up getting something a little narrower and smaller for comfort than the Glock 27. The 5.7 would be mostly for range fun

I think the 5.7 has amazing potential as a full size service pistol. As long as you can manage the five or six inches of barrel you need to get the bullet up to warp speed, it will be a ferocious man stopper, with less recoil than the 9. The 9mm will always shine for subcompact carry, because it's lethal in a short barrel but still controllable. And you can get a 10-12 shot 9mm in a ludicrously small package. However, my caliber of choice is... 40 S&W. Largely because I live in a 10-round state, and can't take advantage of those those insane magazine capacities that 9's and 5.7's have. Since I got my .40's before the ban, I get 11-14 shots. And with 155 grains of lead zooming along at 1200 fps, whatever I shoot is going to feel it.

5.7 in solid copper is the way to go. 9mm in solid copper is also the way to go. All of the hollow point stuff is bordering on obsolete. And the idea of using the expanding bullets to create that larger wound channel is not even really the solution or reason for why a person drops instantly, it's the critical hit of the brain or central nervous system. So as long as you have the penetration you should be able to achieve that. It also requires that you have a good amount of energy to shock that area if it's happening via proximity to the wound from the central nervous system. So long story short, 5.7 can achieve this with the correct round, just like 9mm, but just like 9mm the bullet technology is how it's going to get there. where the bullets are going to mainly differ currently is barrier penetration and cost. 5.7 will never penetrate any barriers better than 9mm with the glaring exception of body armor as a barrier. The cost 5.7 is never going to be as cheap as 9mm. But as an alternative for a side arm in a combat scenario, the flatter shooting, longer range, capacity and armor defeating characteristics and weight of the ammo, make it probably a better suited backup. Even as a primary weapon for police work those characteristics do come in handy. However the one thing that would concern me is windshields and sheet metal body panels which police frequently deal with. As an alternative to 380 I think it's better in regards to capacity and maybe even recoil and ft pounds of energy. Honestly i think the biggest thing holding it back is cost and the government because if they started adopting it more for the infantry the rounds would be good to go and if the government stopped threatening manufacturers of ammo with armor piercing restrictions or construction material limitations(like not being able to use steel or bronze etc), rounds that require tumbling and penetration like 5.7 would have better bullets by now and those qualities would be exemplified. But instead you see a lot of these rounds kinda overweight and using soft lead and soft ballistic tips, that are purely there to prevent it from being able to go through armor and have the government on their backs. So how many rounds are actually that dependent on bullet construction to make the proper penetration depths and actively designed to be loaded with less powder and designed to have less penetration? Like 45, they're constantly trying to make it go deeper and faster. Same thing with 380 and 40. Same with 9mm to an extent. But 5.7 you have manufactures tip toeing around the restrictions and fear of bans. Imagine trying to design a 556 round that DIDNT go through level 3 armor. Maybe I'm reaching a bit but you get the idea. So i don't know, i think there's a lot of potential there and I think in the future these bottleneck cartridges like 5.7 and 22tcm type rounds are going to come into favor specifically for the lower recoil, lower weight and armor defeating reasons. Think judge dread type guns.

I respect your opinion and perspectives. I EDC'd my trusty-dusty Ruger P85 for decades, and still own/use that pistol. I like it, it's never failed to perform. It IS a bit bulky and a tad heavy (For a 9mm), but that wasn't the main reason I retired it. I now EDC the Ruger 57. I caught so much flak from my fellows about choosing this caliber, right up till we compared it side-by-side with their 9mm (And other, larger calibers) platforms, against varying targets (Paper (For groupings), Gel, Various melons and water containers, then cinder blocks/bricks, and finally metal.) What I love about the 5.7x28 is its magazine capacity, weight, slimness, FLAT shooting, no real felt recoil or muzzle flip, and especially- The variety of ammunition you can use. I don't get that with the 9mm (Or at least, not as easily). By far, what I love the most about the Ruger 57 (Though please, Firearm Gods, SOMEONE make a better trigger for this pistol!), is my accuracy with it. For myself, being able to hit what I'm aiming at (And I practice with moving targets and various postures while firing), is accuracy. So, loved the video, got yerself a new Subscriber ('cause I respect and try to show my support to my fellow 2A Advocates/Enthusiasts!)!

5.7 is my all time carry

When i shot this gun, the joy of shooting aspect was very high. Accurate.

The only reason 5.7 didn't replace 9mm was the USA didn't back NATO's play (like always throughout history)(and perhaps because US Gov is too afraid to allow its citizens capable and deadly weaponry). We've always preferred our atom bomb approach until we're forced to admit it's impracticalities.

I bought a 5.7 rock more as a range toy and its now my edc

I like the video. A lot of people don't even know what a 5.7 is😂. My opinion and perspective is a bit more practical. I think the 9 mm is very practical when it comes to conceal carry. The only thing larger than a 43x that i conceal is a 1911(in a veriical shoulder holster). 1911 is very thin and conceals perfectly when vertical. Anything that I open carry or use for self-defense in my home is 45,10 mm or 5.7. with the 5.7 you get quite the ammo capacity and almost zero recoil and with the 45 and 10 you get true stopping power. It's practical for me because I have large hands and I can control recoil on any gun very well. Most of the 5.7 is very easy to shoot one handed. Very handy in close quarters.

All it takes is for a person to try it one time to be sold....I just purchased the Ruger 57 and fell in love instantly and ordered the Ruger LC 5.7 carbine to go with it and 5k rounds of ammo to match....The Ruger LC 5.7 carbine is soooo much easier as my truck gun vs my AR15...It's just easier to handle in my truck... I went from not caring about the 5.7 to instant love...

I keep seeing one down side to the 5.7 is it's size for concealed carry. I did a side by side comparison of the S&W 5.7 to the Colt 1911 and they are almost identical in size, the S&W was much lighter, has much lighter recoil, and almost 3 times the capacity as the 1911. I will take the 5.7.

A street thug took out three people with a 5.7 in Chicago. That round is devastating and depending on the area, I carry mine when I dont want to tote around an extra mag or bother with the weight of my 10mm. Its almost full size season so I like having that 20 rd capacity in a lighter full sized gun. Nine mill is only really effective in +P, but regardless , nothing you carry is going to be much good against a Glock with a switch on it.

5.7 dumps more energy with less penetration than 9mm. While 9mm will perform better in situations involving penetrating soft concealment, the 5.7 will outperform all standard handgun rounds strictly on human targets. And better shot placement equals better chance of winning. It’s called terminal ballistics and always ends up in one performance factor, energy dumped on target.

That smith 5.7 is a great gun thou. Self defense rounds aside.

Put this round in nothing less than 10.5" barrel and you have a formidable round, flat shooting, penetrative, high capacity, and yes lethal.

I'm confused as to why so many guntubers spend time poo-pooing the 57 yet seem fascinated with the MP7. I seriously don't get it

All 5.7 needs is more affordable platforms for people to buy which would eventually drop the price of ammo.

Nice camera work

@3:45 Are they target shooting on King Kia's planet?

It may not over take the 9mm but it is a great defense rd. Way better than the 9 imo.

I think if we saw a company make a good PCC in 5.7 with better designed and more reliable mags that could hold 30 and 40 rounds, it'd change its popularity. Personally, I'd love to see B&T make something in 5.7. Maybe a GHM, SPC, or a TP series. It'll never surpass 9MM, but I think it will change how popular it is. I still don't think we've gotten a good PCC in 5.7. I think the CMMG Dissent is a good option, but it's really just an AR variant. I'd like to see something unique, reliable, and not a variation of an AR.

While it may not be 5.7. I feel like a similar round is the next step in duty pistols. Cop handguns have kind of peaked with optics, flashlights, and the great ballistic performance of 9mm, I am not quite sure where it could go from there besides to a 5.7 like-round with more stopping power

IF the cost of 5.7 go down. IF gun manufacturers can make compact, sub compact & micro pistols in 5.7, then 5.7 WILL take a major leap in ammo sales.

I am not a gun expert or proffessional So correct me if I am wrong The reason why 5.7 cannot compete with 9mm as a pistol round to sum it all up from this video; 1. Stopping Power 5.7 is around 500 - 550J 9 is around 550 - 750J 5.7 .224 inch 9 .355 inch 9mm however can expand around .45 - .5 inch. creating 2 - 2.5X more size for a much greater energy. 2. Firepower Some 5.7 offers 20 - 30 rounds Some 9 extended mags offers 20 - 30 rounds. 3. Penetration Some 5.7 are around 2500 fps Some 9 are around 1300 fps Some 9 however like the "Liberty Civil Defense" 50 grain are around 2050 fps. At this rate the they are both L3 Body Armor Piercing although 5.7 will still penetrate deeper at the end of the day they both beat body armor. 4. Recoil As mentioned brands like the "Liberty Civil Defense 50 grain" are said to be 30 - 35% less recoil than standard 9mm. 5.7 are said to be 25 - 30% less recoil than standard 9mm. 5. Cost I think regardless you should invest some on more expensive rounds if you think they will save your life and be more effective. More especially from a civilian POV Final thoughts; Is 5.7 a bad round? NO! Why? Because of their SMGs P90 for example holds 50 round and are lightweight compared to 9mm 30 rounds. However some 9mm offer 50 rounds or even 100 rounds. They cause alot more weight.

I can arm myself with whatever I want! This is America! But yeah, I wouldn’t trade my 9mm 😅

It's simple: name TWO instances of when you saw 5.7mm ammo on the shelf. I've only seen one box in my whole life. And it was a whopping $40 for only 25 rounds...

I disagree. The 5.7 has more ammo capacity, better penetration and better recoil management than a 9mm. Some people carry full size handguns with no issue. Carrying a 9mm with 23 rounds would be possible, but then you add on more weight and you lose the concealability when you put that extended mag in. 5.7 ammo is official NATO ammunition used by modern militaries, and is not a wildcat caliber like 30 super carry, so it will be around for a while. You can get 50 rds. of AAC for $30 a box to practice with. It's not as cheap as 9mm, but then again, shooting is not cheap.

FN really shot themselves in the foot with the quadruple-figure price of the Five Seven, which drove away more than a few potential customers (particularly with the unique nature of the 5.7*28mm cartridge, which I suspect could be due to FN not licensing it for most ammunition and/or other firearm manufacturers). OK, it's a military/police pistol first and a civilian one second, but my point remains.

Cost and availability make NATO 9X19mm Parabellum the winner. Very few people are shooting past 50yrds with a handgun. It's still a very cool caliber and a collector/enthusiast gun caliber. I want the S&W just for the innovative tempo barrel design. They need to put that barrel design option for their 9mm models.

Comparing 5.7 ammo cost with cheap 9mm yes it is more but comparing it with the ammo people carry it is the same or sometimes cheaper.

If PSA launches the compact Rock AND starts producing 5.8 ammo, that’ll tip the scales

I love rich people. They spend their disposable income on technology I could never afford. As long as the tech is practical, they will continue to spend their $$$$, other companies develop to capture a market share, and 20 years later I can afford it. The more rich people shooting, the merrier.

If you are into your 2A or like it as a hobby, and especially if you are a serious shooter YOU will have multiple caliber, pistols, revolvers, rifles. I just brought a VP9 that I caught on a great sale BUT I am looking to catch a good deal on the SW 5.7. So saying it won't compete I think is a little miss leading, they are very comparable. If you want a 5.7 go get it

Will we see smaller 5.7 pistols for better concealed carry?

5.7 is a good round only if they are shot through a carbine or long barrel with atleast 8 to 10 inch in length. If they are fired from ahandgun with 5inch or less barrel, then it's no better than any other smaller handgun rounds. As it only travels at 1400 at max from such short handgun barrels while it's max velocity it can do is about 3000 fps from longer barrels. So whats the point of 5.7 handguns?

Imagine living in California with this round.

I like the idea of 5.7, and thanks to PSA, there is an affordable option available. Ammo is expensive, but there are worse ways to spend money. With guns and ammo, we don’t need an either this “or” that, we must embrace the power of “and”! This “and” that!!! 😊

9mm was out for 60 years before it was widely adopted in the US….just saying

With the 5.7 all follow-up shots are on target because of the low recoil. The 9x19 is much harder to keep firing on target. 5.7 means all 20 rounds are hits, while in the same duration 9mm is at it's 4 or 5th shot struggling to keep hitting it in the same place due to the recoil of each shot.

Anyone interested in a Shield Plus performance center ported barrel has about 400 rounds on it. Looking to connect with a buyer works out better for both involved. I want to buy Canik rival parts

5.7mm is clearly superior to 9mm for *duty sized* pistols. Period.

5.7 will always be better then 9mm all maters about accuracy and speed, and that's all I need

Kinetic energy comparison between 9x18mm and 5,7x28mm: 9mm --> 500J - 700J depending on the round acc. to Wikipedia 5,7mm--> 500J - 800J depending on the round acc. to Wikipedia Conclusion: Basically the same kinetic energy for both bullets, however the 5,7mm has a lighter recoil, is smaller and weighs less. Maybe costs, availability or other factors might be worse for the 5,7mm however performance wise it is the better newer bullet design.
