awesome video man, the mpx has been on my list for review for quite a wile now.

Big thanks to Ed for helping an awesome KZfaqr like KS! Great review and range videos by the way 👍🏽

Hands down my favorite firearm in the collection. Even better suppressed.

I have the 8 in barrel version and I love it. Runs so smooth and no issues to date. I was lucky and picked it up on sale for a little over 1K without the brace. Money well spent.

Ironically, I just shot one of these today and loved it!!! 😍

Very nice KS. Thanks for the video!

I've yet to get into the AR pistol concept... but I like seeing ones that are done right!

Good vid man. I've been wondering about these. That little dust cover cracks me up after years of seeing ar dust covers

I plan on picking one up soon. And I love centerfire, always helpful and get me what I want.

I enjoyed the outtakes KS, we are all human and make mistakes. Great presentation.

Great video.. I just got the MCX and fell in love with it. Now I'm thinking about the mpx for that pistol caliber itch .

Wow, that is one sexy pistol! I'd love to get one of these some day, and that group you shoot towards the beginning was insane! Thanks for the drool-fest brother, I'm in love with this puppy!!

Love the bloopers! 😂🤣 more bloopers!

I own the sig version of the ar15 and love it. It is heavier than other manufacturers, but it's a Sig so it's better built with better stock. Going to have to save up to buy this, but it's a must have.

Was in love with the 4.5 inch keymod until I bought the 8 inch keymod Gen 2 with the new SIG side-folder brace and a Romeo 5 for $1451.00 at Prepper on March 5th. I added a Timney single-stage 3lb straight shoe trigger, and today I got a the new MCX pistol grip for it in the mail from SIG. This is the way the gen 2's should have sold. Shoots like a laser, it even makes me look good.

I love it! u helped me make my decision thank you my friend

Any suggestions on a similar PDW that would be Marine Grade? I need something that will hold up in a salt water boat environment. Thanks

Yeah I want to take the safety off of the right side but I'm lazy right now. I put a Timney pcc trigger in it. A Surefire mini scout with pressure switch fits perfect on top of the rail. I carry mine in a backpack, it fits great in the laptop pocket.

Battle Arms Development makes a great variety of safety levers. I do have a short throw on my sbr.

I like my Sig's for sure but the price.... Great review as alway's

That was a review, thank you

Oh my God... I just subscribed and shared and hit the notification button... I put this on a college football channel.

I have the MPX carbine model. Very accurate and ergonomic.

Greetings KS! I just purchased the Grand Power Stribog. Awesome 9mm pistol! I put the stock adapter and the SB3 brace on it. Nice!! Any plans for a review on that one? Blessings, Jim

I absolutely love my MPX-K and 100% agree with the hideousness of the copperhead! 😂 The recoil design on this is insane and I’ve never shot an arm with as much consistency as this beast!

I love my MPX Copperhead some much that I got the MPX 8 inch version in fde and the new folding brace. Love the MPX so my Scorpion is getting jealous. Great review as always.

Current 2020 MPX-K 4.5" barrel 9mm has pivot brace, folded its now 14.5". MLOK handguard. Timney flat trigger 4.5lb pull, zero creep. But still stupid expensive at $1900. Bought it anyways because the Coyote Tan color looks cool :)

That’s a well crafted pistol 🔫

All the Sigs are surprisingly overweight. I’ve made it my life’s mission to build a better pistol caliber carbine that is: 1. Ruggedly durable. 2. Very accurate out to 100 yards. 3. Highly concealable. 4. Reasonably priced. and 5. Well balanced and light weight. I have purchased several of the best contenders, as well as a few odd duck budget pieces for my study and have begun engineering something I believe will make a lot of PCC fans very happy. It’s main feature is the mag well design, which, for obvious reasons, I cannot talk about before its debut at Shot Show, but it’s been a personal pet peeve of mine with other manufacturers for many years. I can’t wait to get it prototyped and in show goers hands. I WILL say I’m gunning (pun intended) for an msrp under $800 with a whole table load of accessories also reasonably priced to go with it.

I have the TACOPs (4" barrel with flash can, 8" rail, brace, factory BUIS, and three mags) gen 2 version of the MPX and it is solid accurate shooter. Easily modified with AR components. Built to last. Price was not a factor for me. I wanted a more solid feel and heft. The Lancer mags are outstanding. Zenith, PTR, and B&T were some other choices. The HK clones are nice, but old tech. No fun without the fun switch like work. Glad I got the MPX. I've got a Romeo 5XDR on it. The ambi safety is not as bad at the CZ. Great review. Slings help with weight as does working out. :)

What makes that particular one heavy is the cqb brace. That brace weighs a ton. The SB Tactical sb1913 is a super light weight folder. The core MPX K is super lightweight.

Love this gun

If you manage to get your hands on a MPX k at this point I recommend you put a 6" aftermarket hand guard on it. Then get a suppressor so that it only sticks out a extra 2-3". I added a radian raptor ambi charging handle & timney trigger & inforce WMLx (among a few other things) to mine Angled Forgrips are legal, no need to stop at just a handstop

A must buy asap!

You have yours set up almost exactly like mine. I have a Streamlite TLR on mine. It is my home defense bedside gun. Agree it is a bit heavy but there is almost no recoil and it is super fun to shoot. However, I do have my eye on the CZ Scorpion Evo3 S2. Hard to find right now it seems.

That is a cool little gun....Good stuff....

Nice review! wish I could find something like this that takes glock mags that isn't a blowback action

Ambidextrous but ejection port is only on the right?? So if I aim with my left eye I have hot brass spewing in my face??

Great video! Does that exact brace come with the gun? Can you buy it separately? I have the SB brace it has a different design.

This was $1800 spent with no regrets, I Absolutely love it and anyone who uses it falls in love with it. Yes its pricey, Sig Sauer MSRP 2 years ago was $2050 when I purchased mine from Shoot Straight. Being the mags are expensive I purchased 1 Gen 2 for $70 and 2 Gen 1's for $18 each. Yes I've had a couple fail to feed but not enough to regret trying out the Gen 1's on a Gen 2. It's happened a couple of times when I first got them but I think its used to them now or I just got lucky, definitely a good way to stock up on range mags for only $18, for self defense stick with the Gen 2's to be safe. Buying 6 Gen 2's at $420 is just crazy unless you're using it strictly for home defense. The cool part is it fits in my 1980's leather briefcase at an angle with 4 mags and a Romeo 5 red dot, very incognito and sleek. I have zero regrets and will buy another Sig, probably the MCX. You get a cardboard box and 1 mag with the MPX so you'll need a case too if you don't have one. The old saying you get what you pay for and this is the Rolls Royce of 9mm Carbines in my opinion.

Well done! Thanks

Cool MPX Sig Sauer KS. Thanks for showing it, but i think Sig Sauer wants to much money for what you get out of their products. Another awesome review Sir

Welcome to the K family!🇺🇸

Is this only available for LE and military personnel? Or can civilians purchase it too?

Looks awesome.

The future of concealed carry, imho.

Cpt.J Great review. Got my MPX K Tac ops 6 months ago and waiting on Sig SRD9 tax stamp. Have run close to 1000 rds. with various ammo types , it has performed flawlessly. I even mixed Sub and Supersonic loads in mag and rapid fire with no issues. No muzzle rise and very little recoil. Its my favorite truck gun. Pricey, but well worth the price.

I don't understand the copperhead unless it's main issue is transport

What kind of flip up brand sights are on this mpx?

I just got one! :) usually you only see the ar pistol carbines in 223 or ak pistols at gun stores. those r cool but if u ever even shoot it on accident in a confined area without ear protection itll be the last thing u ever hear.

Just subscribed

It's an awesome setup for sure. Much as I would like to have one, my Shooting Club has one decked out like the one KS reviewed for $2295 + TAX! For me the Perfect PDW is my PS 90 w/E O Tech 512 Red Dot. 50 Round mags are nothing to ignore and I own a FNH 5.7 pistol. The 5.7 is flatter shooting. If I were to buy another PDW I definitely would buy this one! It's hard to ignore it, who knows it may appear in my collection someday! )

Love mine but thinking of trying to change the brace

Those are definitely cool little guns. Only complaint is how wide they are! I really want a PCC that’s slim and lightweight

Hey KSGG, THANKS👍 & CHEERS🍻 😜

I brought this gun when it first came out without the brace I paid about 1,300,take it to the range 3 different times and it jammed all the time I was so disappointed I sold it and get the ar15 ,but I think sig was having so problems with so of this guns,hopefully they fixed the problem now but I want to get another now they do look bad ass

The House Division 1

LOVE those outtakes! I never knew you actually made mistakes. BTW, can I borrow $1600?

Great lookig gun

I hate ambi controls on an ar style rifle cause I always have issues with the safety lever and I wear small gloves. Can’t imagine anyone not finding issues with it ever. I only have one this is ambi and I solved that issue by removing the safety level and rotating it about 45* so it’s out of the way. One day I’ll spend $3 and buy the blank but it works lol.. (should add I only rotated the right hand side the left side is still normal.

I thought from the pic it was a 223 round, and thst would've been amazing.

beautiful

Me likey, but me live in the UK so me can't havey, 😖

@2:38 Glock needs to make one , I'll take mine in 10MM with a 16 " barrel . If the mag is in that spot , the grip needs to also hold an extra mag . I think the mag would be better in the grip to make it more compact , like the CX Storm & UZI .

Nice Assault 👍

Nice review as always. This gun is too expensive for our budget but not everyones of course. The CZ variants would be closer to what we can afford.

My wife and I went to our local range (Point Blank) this past Saturday, and the range worker said that they sold a Sig MPX for $900 (brand new)?! He said that it was there for about 2 years, and in this case, they could not sell it - so they clearenced it. How come I/we never hear about these things until it's too late? :)

This is probably the most bad ass looking SMG currently on the US civilian market right now. Is $1600 really a lot of money? We commonly spend that on pistols that have a very limited range of use. The MPX definitely looks practical for home defense and down right fun as hell at the range.

I have NO idea why I would need one of these.....but I’m already trying to decide where to order mine from....

for 1800 - damn... I rather buy the 9KT PTR. Loved that gun in Goldeneye

The mpx k looks super sexy. Great review as usual.🙌🏿

This is legal in New York , just have to take the pistol grip, mag,suppression,stock off. Oh forgot, I think the barrel is toooo short.

Just curious...why do you prefer this over the Copperhead? This is obviously closer to my Gen 2 MPX carbine rifle. Thanks! (Congrats...I just found out you're a regular at CF.)

The Firearm itself isn’t overpriced but the mags are the deal killer for me. I like to have at least 10 mags.

Scorpion 30 round mags are $20 at my LGS.

It kinda looks cute xD

The new CZ Scorpion micro vs SIg MPX....I think I would go CZ. More aftermarket support. Better reliability and a lot cheaper.

A friend let me shoot this a couple of months ago and I was blown away!!!!

Nothing beats a P90

I don’t like the fact that the mag release and bolt release are so close together. Under stress, that will result in a lot of dropped magazines

Can you add a binary trigger?

Love Sig and the MPX is nice. 2 grand nice though? I personally dont think so.

Does it come in any other caliber

i like it i like it a lot :)

I want this in 10mm with 30rnd mags.

I’ll take two ak-v instead Thanks for the video

I have a CZ micro, Extar EP9 and a PAK 9 AK. We should set up a place and time to meet.

Gorgeous

Not a bad gun but I think the scorpion micro would be better just the fact that I can get 3 magazines for the price of one mpx magazine. I do love my scorpion after all the upgrades I’ve installed on it. Still mpx would still peak my interest to shoot/rent. Good informative video 👍

Another great presentation. Obviously, I'm interested in learning about this gun; which is why I'm here. My question is, for the average citizen, what is the advantage of this, over say, a Glock 34, with 33 round Glock magazines? You've handled a lot of guns, so I'm asking your opinion; not challenging the efficacy of this weapon.

Ahhh yes my favorite pdw in bf4

How much it cost for this model?

Valkyrieeeeeee

need it in 357sig

I have the 8" MPX. The joy of the MPX is almost smooth as silk light recoil due to the short stroke gas piston. Compared to blowback there is a major difference. Worth the price? Very subjective but since I could afford it that's what I got. Get the best you can afford or willing to pay and as long as it works for you that's great!. The more of these pistols or pistol caliber carbines, whatever the brand or action, in civilian hands, the more Pro 2A voters we have supporting the cause! Gun Shaming is STUPID!

I was able to pick one of these up for $1080 plus tax a great deal!

I would totally buy one if in 45

Nice Review Brother, There are a lot of great choice PDW’s out there for sure. Outtakes 😂 Carry on

Will this hold Glock magazine

I want to build a 357 Sig carbine .
