I own lots of different calibers, but I love my 40's. They just hit really hard. I have a hard time respecting any gown man who finds the 40 recoil too much to handle. The difference is negligible at best.

Going back to 9mm is a bad idea in my mind, it’s like we’re not learning our lesson from the 1986 Miami FBI shoot out.

40 is still the best round overall: capacity, penetration, velocity, and POWER.

.40 isnt a compromise between 9mm and .45 its more powerful than both of them lol

Forget the 9mm. The .40 is not in decline.

My first handgun was a Sig Sauer P229 in .40. I loved the .40S&W, now my main is a Glock 19 gen 3 with Truglo night sights and a TLR-7 light for home defense. I might get a Glock 23 down the line. I'm slowly falling in love with Glock firearms.

I personally don’t see the 40 s&w as a “compromise” round especially with it’s capabilities to launch a heavier grain bullet than the 9mm at a greater speed than the 45 acp. If we’re talking about duty rounds of those three than I’d say the 9mm had caught up with a bonded bullet and maxed out to +p/+p+. As well as all three of those rounds have benefited with better powders and bonded bullets making them equal so to speak. But here’s the issue with that though, many concealed carriers are not going out of their way to purchase and practice with duty rounds and are getting “standard” loaded non bonded self defense rounds. With those “standard” self defense rounds, the 40 is a more guaranteed potent caliber with the benefit I stated in the beginning of my comment. With the 165 grain bullet you’re getting a faster moving heavier round than 124 grain 9mm that has more potential in barrier penetration than “standard” 9mm or 45acp. If you want something with more penetration than that you can go 180 grain which lowers the speed a bit but is still faster than 45acp. I hope didn’t come off repetitive, but with any ammo droughts with all the duty 9mm rounds that made 9mm more viable for duty use being bought up by the government and panic buyers, folks would lean towards 45 acp and especially the 40 s&w with their “standard” more guaranteed performance. Many who complain about the “snappiness” of 40 are shooting small subcompact handguns when in reality the 40 is a duty round that flourishes in compact and even better in full-size handguns. I think internet marketing has overhyped the 9mm to mythical proportions and has belittled the 40 s&w in all the wrong ways. But great video.

Love my Glock 22 and Sig P250 in .40. Recoil isn’t bad at all and I love how hard the round hits.

The Glock 23 is my shtf gun, no doubt.

I don’t base my choice of caliber off anything the FBI says. .40 is a viable caliber and I most certainly wouldn’t want to be in front of a .40 caliber bullet.

So much more info then a simple review and taught me alot more about calibers, barrells, etc that I'd been looking at. Thanx

My first 40 was a Sig p239 and it jumped around making 2nd and 3rd shot a lot harder to be accurate with. Bought the g23 and it absorbs the recoil like a dream. When your using a 22 or 23 you know your throwing lead downrange. Today they are my go to guns unless I'm in grizzly territory. Then it's the 20.

My issued firearm was a G22 G4. I loved this pistol so much that I bought one for my personal handgun. The length and the hand grip gives above-average accuracy easier to achieve. Great pistol! Getting rapidly back on target is easier to acquire by firing from the point of trigger reset.

I started for the department that I work for back in April of 2007. The department uses Glock 22 handguns and getting firearms certified in the academy was my first experience shooting a firearm that was chambered in .40 S&W. From training with them at work, I really fell in love with Glocks, the Glock 22, and the .40 S&W caliber. In early 2009, I think somewhere between March to June, I bought my own personal Glock 22, that was identical to our duty G22’s at work. It is a blue label, Gen 3 Glock 22 with Glock factory night sights. Out of every firearm that I own, and there are a lot! My Glock 22, has more range time on it over any other firearm that I own. That gun allowed me to have a lot more range time when I was off duty. Because the State has a strict budget for the department, we could only qualify once a quarter, or on average, once every 3 months. But if someone qualified in the first month and first day of the first quarter and then qualified again on the last day of the last month of the second quarter, then they would essentially go 6 months in between training. We then had a 2 day annual refresher course that we are required to take once a year. With my G22, I probably shoot it better than any other handgun, simply because of the range time on it. In my 11 years of owning it, the gun has never malfunctioned. It has also been used in every weather condition from sub zero temperatures to days that were over 110 to 115 degrees with no wind and on black rock with black tires 15’ high on both sides of the range. My personal G22, and the range ones, in addition to being used in every weather condition have also been completely exposed and covered in ice and snow, water, and varying degrees of sand, dirt, and mud and the Glocks still always function. I don’t know how many rounds I have put through my personal G22, over the years but I know that many of our range Glocks have well over 50,000 to 60,000 rounds put through them. Possibly even well North of 70,000 rounds put through them at the departments ranges and all but I think either 2 or 3 range guns still have all of their original internal components that they were assembled with when they were built and were brand new. It is because of those reasons and my observing and training with them that in my personal opinion, I believe that they are the most reliable and durable handgun ever made and also offers the best longevity. I also love and own several other types and brands of firearms too, but I will probably, always trust Glock the most. I think I now own 13 or 14 Glocks in total and with more to be bought. My goal is to eventually own every Glock made, from every generation made and in every finish or color scheme made. This past Friday, on May 29th, I went and purchased another brand new Glock. It is a blue label, Gen 4 Glock 23 with factory night sights. My daughter graduated high school on Saturday so I have not been able to take it to the range yet but when I do, I will be completely stoked. My every day conceal and carry is a Gen 5 Glock 45 MOS. I absolutely love that gun too. I really wish Glock would release Gen 5 models for all of the handgun calibers that they make. I also with they would release the G19X/G45 in other calibers too. At least in .40 S&W and .357 Sig. Call them either the G23X and G32X or some other number that is new, after their patent. The thing that I love the most about my G19X and G45, is how well they are balanced. Much more so than both the G17, and the G19. The full size grip and frame mated to the compact barrel and slide work incredibly well together. It’s also nice being able to hold an extra 2 rounds per magazine.

I have carried the Glock 17 & the Glock 22 on and off duty and my scores for qualification are identical. The recoil is really a non-issue for me and my peers while admitting only a slightly stronger recoil. Agencies who say some officers have an issue with the 40 cal are agencies that have a few officers that cannot shoot anyway no matter what they're issued. Many departments may issue a Glock 9mm or another 9mm still allow the 40sw and 45 ACP to be carried in and out of uniform.

Love the new Gen5 Glock 22. I also love my Gen4 Glock 32 (.357Sig) with my 40sw barrel.

This video is one of the most comprehensive and widely explained in terms of differences between those five Glock. Thank you so much!

Fantastic! Full of information. Head and shoulders above the usual "Hey I just bought this gun" videos. Good job.

Excellent, detailed video. Thanks for taking the time to explain everything.

Great information about the difference on both 40 caliber and the 9mm glock. Thank you.

This is meant as a general statement. If you find a .40 "too snappy" or "harder to control" then you need remedial training. NOT a hardware solution (moving to 9mm) for a software issue (terrible fundamentals).

Having grown up in a law enforcement family full of ex Marines, it was always hilarious to me and many of them over the last 2 decades at least, the bouncing back and forth between 9mm, .45, etc of many agencies. Many don't realize it's not always tactical for decisions but contracts with gun manufacturers in particular Sig and Glock. Those two companies have battled for years for law enforcement contracts so they switch brands and sometimes calibers for a while. Many Central and Northern CA local agencies recently contracted with Glock for the Glock 21SF .45 and the pricing is awesome for the bottom line, but mostly the officers love the gun and I can see why owning one myself. It's a shorter frame, grips well and doesn't shoot like a .45 but gives you the power of the caliber. And it is extremely light which I think is what the officers like most honestly. And some say anecdotally they've noticed officers winning more gun fights (look up Lodi CA PD) recently with the Glock 21SF. As with anything though it's just accuracy and training ultimately that prevails. 9mm, .45, .40 etc. In the hands of the well trained shooter the training will prevail vs what round you're firing. A fact the military has known forever

Excellent video. I thoroughly enjoyed it. Just subscribed. Over the past twenty years I have purchased four used LEO Glocks, three 22 and a 23. Great value for the price, ($300-350) I also purchased a new 27 and 17. I recently purchased Lone Wolf threaded barrels and conversion barrels for several of them. I am ambivalent about the 357 Sig as I am very satisfied with what I already have. I do appreciate having the option of using that caliber though. I will have to spend much more time at the range before offering an opinion as to whether the conversion barrels are reliable enough to bet my life on. Until then, I will CC my firearms in their original caliber/mm. Thank you for a professional and informative video.

Love my 40s never understood the hate. My 22 and 23 are awesome

What I like about the .40 S&W round, is that there are so many bullet weight and styles compared to most the other pistol calibers. The so called 'snappyness' does not bother me. I suppose that comes with years of shooting.

Im looking to get my first glock and was debating over 9mm or .40 and your video awnsered all my questions and has been the best vid i could find on youtube, thank you!!!!

Great vid! I love my 40's.

This is really cool that the Glocks have interchangeable barrels allowing you to change the calibers. This is a really important feature.

I bought a Glock 23 some years ago and have two Sig P 229s all in .40 S&W. Even with the increased cartridge modifications of the 9mm I consider it only a marginal self defense round. I also prefer the .45 acp over the 9mm. The 40 S&W has about 35% more bullet weight and comparable muzzle velocity. and works well in double stacked magazines.

Favorite Glock will always be a Glock 23 gen 3

Love my Gen 3 Glock 22 ..keep it as my bedroom gun .. 180 grain Ranger T

Never understood the recoil bent against a .40. Name the average popularly fired cartridges at a range and I likely shot them. I felt my .40s were not a problem in recoil, and in specific pistols I felt it had more accuracy and control than less powerful rounds as casual shooters believe it wouldn't.

Bottom line, the chicks and dudes that couldn't handle a 40 caused PDs and the FBI to go down to a 9. Thanks.

Thank you - great video.

I would like to see you do an update with the Gen 5 Glock 22 and 23.

This video was made 2 years ago and guess what? Most police are still using the 40 . I havent seen any decline in the 40 in the past 2 years at all. Reassurance in micro 9mm? Sure. But 40 cals are selling just fine. People can debate all they want but the 40 isnt going anywhere.

I’ve owned at least 5 different glocks, my first was my G23, bought in Jan 2012, I still have it, it’s been my nightstand gun for 11 years now, I also had a G27, I liked it but sold it.

My EDC is a G22 with a Holosun 407C X2 and TLR-1 HL in a Bravo Concealment IWB holster. I LOVE IT!

Great video

Outstanding presentation. I've been following these issues for years and have never heard a simpler, smoother more accurate report. I don't know who this guy is but I wish I did.

You can exchange the recoil spring guide rod with steel or tungsten for more weight out front to help recoil recovery time.

Vid deserves a lot more likes 👍

I have carried 9mm, .40, .38 and .45 at different times during my days as a cop and a soldier and of the four I have a slight preference for .40. That being said I am ok with all those calibers in a gun I can shoot accurately.

Very well explained

I fully converted a few G23’s to 9mm. The ejector, extractor and extractor depressor plunger are all that’s needed. Functions 100%.

Very thorough.

Nice Glock collection! Glock 23 with 180gr Federal HST is as good as it gets

Just received a police trade G22 and a G23. Both Gen4, Both with 3 mags, grip modules, and all the accoutrements. Holster wear was to be expected, but there is very little of that. The saying is accurate: Carried a lot, and shot a little. Inside, was still Glock perfection. Oh! and these two new pistols, were only $299.99! At Gideon Tactical. Yes, I'm a fanboy BUT, I still want a VP40. lol

The new loads on the 40 are in par with 9mm..still a monster and accurate....

My 16 year old, 100 lb daughter shoots the 40 S&W very well. She has no problem and no complains about 40 recoil. If someone finds the 40 too "snappy" i suggest the gym. The 9mm is actually a higher pressure round at 38000 psi as opposed the the 40 S&W at 35000 psi The 40 is the superior round over the 9mm ....

Underwood's 155gr xtp is a lovely deer hunting round!!!

The 9mm conversion barrel cost right around $200 and change. Throw in the 9mm clips at around $26, say you buy 3 of those so that brings your initial cost to right around a little over $300. I don't see the economic practicality of this if it means the cost is about 50% of buying a dedicated 9mm. Just go ahead and buy a new dedicated 9mm. For me though, I'd stick with the .40. It has more umphh and the recoil is the happy medium between a .45 and a 9mm.

I just bought a 23 g4 police trade in I hope I don't regret it I have always bought new I couldn't find a new one. The g5 slide is wider than the g4 so it won't fit in the holsters with the rest of the glocks

Just bought my .40 cal Glock22 Gen 3. It came with a conversion slide to shoot .22 cal Lr. with mags. I'm getting a 9mm barrel and mags. I don't think I will get the .357 Sig barrel because ammo is too rare and expensive. But with it you can shoot "four" calibers from the same gun.

Neglected to make the distinction, at least in the beginning of the video, between conversion barrels and standard Glock barrels.

My favorite caliber.

I noticed zero difference in recoil from 9mm 147gr from a .40. The 23 will be my next purchase.

IT'S not a compromise...it's in it's.own league

Just saw some LEO trade ins at a local gun store, Glock 22 & 23s, both in Gen 3 & 4. I don't have a Glock yet or a 40 cal handgun, but seriously thinking about a 22. Prices right now are for a Gen 4 22 are $475 reconditioned. It wasn't on my radar but I live in NJ and the gun laws are ridiculous and getting a handgun takes a permit and can only purchase once every 30 days, plus a permit takes about 3 months to get, at least right now. So the appeal of having a 40 cal then swap in a 9mm conversion barrel so in essence have 2 guns in one is nice, and could even go .357 SIG. So, I would imagine the consensus would be to do it, it's Glock so really can't go wrong, am I right?

"The ballistics [of the new 9mm] are not as strong as the 40 caliber, however they're not exactly inferior anymore either". I'm confused. If they are not as strong doesn't that mean they ARE inferior?

i have a 22 g4 in 40 cal ... its awesome!! im not a tall person, neither i have big hands... id say s/m hand size, i can handle the recoil perfectly fine and always stay on target. i love my glock 22 in 40 cal, soon ill buy a glock 23 for concealment. its always how much you practice and how confortable do you feel with your gun. ive shot 9mm and i can be so damn precise, obviously bc i got use to 40 cal, however id rather use 40 cal than 9mm for self defense.

Took my g22 gen 3 replaced with true precision drop in added Texas black rifle compensator apex trigger trijicon hd night sight an a plus 4 mag base from hyve !! This is my racegun an it's dead accurate ant the reset an trigger pull 3 75 is very smooth , I like 9mm I have a g17 gen 3 racegun also but to me snappy is better

Yu go boy...that's the biz...

I have G23 gen3 with a conversion 357 sig barrel... And g17 gen 4 along with 357mag 2" barrel 7shot. MY EDC

I love my .40. I have all the g.40 family

I like all calibers even the 22lr

First thing a do with a new Glock is put new sights on them. The factory sights are way off the mark.

Sold my Glock 22. I think I need a 23 though. We shall see

I know it’s not PC; but I think the reason for switching to 9 mm is the increase in women entering the military and LEO agencies. We’ve already seen the decline and physical standards. Having smaller hands and weaker grips is largely the issue.

I have no issue with 40 cal recoil I also have the model 20. however I dont go through qualifing.

Anybody help me out here... Looking to get a glock but there are so many versions. I want a 40 cal but which one is the most accurate? Does a longer barrel = better accuracy? Is it just the size differences?

9x19mm sucks terminally. Bullet design only helps it suck a bit less. Ive saw and heard of perps taking hits, sometimes dropping, sometimes not, and sometimes dropping, then getting back up to either keep attacking, or they run off and are found later at the hospital or in some alley way, ditch by the road, abandoned building, or parked car. Never heard or saw such bs regularly going on in departments using .40, .45, or .357 magnum or .357 Sig. So. 9mm might be all nice and gentle and require less training to get improved range scores by small stature men and women? But so does .22 long rifle, .380 ACP, .32 ACP, or .25 ACP. And I don't hear of ANY police department or military issuing. 22 lr, .380, .32ACP, .25 ACP to its personnel these days. For good reason. They can all still kill and can be easy to train with and accurate. But they severely lack the terminal destructive capability to stop bad people from doing bad things to good people with any degree of reliability. Most handguns have this same trouble. But some don't. The .40 S&W is one of those rare cartridges that was purpose built to NOT be just a shortened 10mm as some like to describe it. But .40 S&W was purposely designed to instead be a shortened 10mm that lost little to none in the way of the original 10mms destructive terminal capability to do enough bone and tissue destruction to STOP a human being with a high degree of reliability, but still high capacity in a magazine and impart less weapon erosion than 10mm usually was cursed with having the capacity to do.. While 9x19mm Parabellum on the other hand is a 100+ year old blown out .30 Luger that Georg Luger, it's designer, thought might land him a financially lucrative military contract from those world militaries who thought his .30 Luger cartridge lacked killing power. Luger got lucky, fairly wealthy, and the world got the 9x19mm Para.

Is the g20/21 slide the same length as the g22/17?

When you been doing push-ups on ur knuckles for a while u build up ur wrists and the 40 doesn't feel that bad

Only issue is jamming failure to feed issues on G23 series with flashlight mounted pre gen5

Do u think a glock 22 police trade in is worth 290

convert to 357 Sig you will love the performance out of it.

Gen 3 glock 40 b.k.a the glock 22 love mines came with a 10 round mag but i bout a 22 round mag and a 15 round mag

I switched my carry to 40. Because everyone now wants a 9mm and during covid i couldnt find 9mm anywhere. All i could find was 40 and 45. 40 isnt hard to handle with proper grip and training.

Still love me my Glock 23 Gen4 ...

Curios: Can the Glock 10mm be converted to .40, 9mm, & .357 sig? Great video, thanks for the info!

I use 9mm in 124 grain and 147 grain on my g23 conversion barrel. The 115 doesn't cycle well unless it's a +p or +p+p for 115 or smaller grains.

What's more powerful the 40 or the .357 sig

I whant buy my first Glock wha is better 22. 40 or 19

40isthebestround

Time for the FBI to show us the Stats at how good the 9mm is in stopping the threat. They need to prove it does the job because the human body is in no way similar to a block of gel. You can push a fist into a belly several inches but you can not do that to a gel block.

NOT an 'in-between' caliber !! Much more .

Scores with a 22 would be better to. Train with your 40 and it will be just as accurate with way more power.

Why they make the gen 5 40s bigger

The 40 isn't a high pressure cartridge. I hear this misinformation all the time. What it has going on is its "peak" pressure or pressure curve is quite quick and fast its not loaded as an high pressure load in commercial duty self defense loads. People don't understand this and it gets explained incorrectly all the time. One of the best explanations on this was done years ago by Guns &Ammo contributor Bob Forker who was an technical editor.

My GLOCK model 22 would be the last one of my 5 pistols that I would EVER get rid of!!! But what is REALLY "FUNNY" to me is you hear PANZIES gripe about how the 40cal is "SNAPPY" BUTyou never hear them say that about the 10mm.

180gr bullet is better than a 9mm. Period. Retired popo. It's doesn't kick that bad. Get over it.

Pity my Kahr isn't switchable

The bullets make the difference in weight when loaded tho.

I have a 9mm Ruger LC9s pocket pistol and it is extremely snappy. I can't shot more than 25 rounds and my hand starts shaking. Now I just ordered a Glock 22 Gen 4 but I figured with a 4.9 inch barrel and double spring that hopefully it wont be any where near as snappy as the Ruger LC9s. It's also a much larger pistol than the Ruger.

I have a Glock 22 and it has less recoil than my Ruger 9mm. I even put a Double Diamond Glock 22 barrel and an stronger guide rod assembly and it is even less than the 9mm. Those highly trained such as FBI and all law enforcement are full of crap if they are that lousy of a shooter. They need to go back to .22 cal rim fire and practice.

I may take a 9mm in a non-vital area...if I get hit with a 40 my.odds of survival goes way down..

The 40cal Glock 23 is a glock19 with a touch of steroids. It's definitely my EDC. Everyone jumped on the 40ty wagon because of the FBI, but when the feds decided to go back to 9mm everyone followed. I have many 9mm guns but I carry a 40ty. The glock 23 is the best shit hits the fan gun.

Good job Brother. Big game calibers start with '3' and Self defense calibers start with a'4'!

If you're a bigger guy with strong arms and hands you can shoot this as fast as most people can shoot 9mm
