If you go back to our Sig Sauer MPX Gauntlet video, you'll see the Sig MPX fails to work if you put as little as a tablespoon of water in the barrel. Sig said they fixed the problem and sent me a new gun. Did they fix it? Does the Sig Sauer MPX now work in water?

*Mac tests out a sig firearm* Sig: *sweats heavily and shakes like moff gideon*

[@Commonwealthcollector]

To be honest this seriously makes me reconsider ever purchasing a Sig firearm, there was a problem they knew about but sold them anyway touting how reliable they are. Also I do find the slight water in the barrel causing malfunctions to be a extreme issue, up here in Montana with the snow it is near impossible to keep water out of your barrel when going through thick brush as snow falls off the trees and all over your rifle, granted that is during hunting season and I'm using a bolt action 30-06 but an mpx as a bug out weapon or a pdw would be a poor choice if it takes so little to fail. The new ones maybe good to go, but it seems like with sig maybe they have another problem hoping nobody will bring it to the light and force them to fix it, great video as always

[@Militaryarmschannel]

People said I was overblowing the issues of water in the barrel. Sure, if you live in a desert it's not likely to be an issue. However, where I live it snows. When you go outside with a warm gun, when the show lands on it you get water. It also rains here, a lot at times. If you're outside in adverse weather it could be an issue. Most shooters never spend any time outside when the weather is less than ideal. For them, it's a non-issue. For those of us that practically live outside, I don't want my defensive arm not working with a dab of water in the barrel. So, I agree with you. Happy New Year.

[@dreadog6425]

Pleases dont buy one, that will leave more for the rest of us. The Model T didn't start and run the first time out. It's part of the process with innovation. Wieners like you discourage innovators from trying new things. I would be concerned if they fluffed the off. The gun is now better because of the process. Sorry for now you wont be able to go lobster hunting with the MPX you dont own.

But, when you showed me the 9mm rounds in the mag, I shed a tear, as its like watching you shoot gold. Lol I'd do just about anything to purchase some decently priced 9mm ammo.

[@BertShackleford]

@@ReverendMeat51 I waited for over 20+ years for a game like Total War: Warhammer (1 & 2) to finally come to fruition. I simply do not have the patience nor the artistic capability to paint miniatures. Plus the rules are seemingly endless. So when my wife and I (used to) play, it was with the stock grey miniatures after they were assembled. That all stopped once I learned about Creative Assembly and their upcoming TWW game. I was so ecstatic that I purchased a PC Gaming _Monster_ computer just so I could flawlessly play this computer game. Longevity was key when I purchased this gaming rig. It was also somewhat difficult to squeeze the trigger on the purchase being a 2A family. The many-many thousands of dollars this computer cost could have easily set me up with a plethora of "got to have it" 2A items. I could have just as easily upgraded to the latest and greatest NODs for the same price with some extra left over for ammo. Nonetheless, I can safely say I/we are happy with our decision towards purchasing this incredible PC I am currently using. Suffice to say that it has paid for itself. Stay classy my friend.

And each has sent it back, Taurus fixed the problem and returned it to the purchaser, free of charge! No problems since then! Yeah?!?!?! Why don't they just assemble the thing properly, in the first place!! And it's not just them, seems like 99% of purchasers, have had to send it back. They keep telling me that I should buy Taurus. I think I will continue to buy Colt, Ruger, S&W, Dan Wesson, Browning, Charter Arms, High Standard, Star, Winchester, Remington, Mossberg, H&R, Armalite, Husqvarna, Ithaca, Marlin, Mauser, Savage-Stevens. New or Used, doesn't bother me. I've got a Remington 1911 R1, and have had NO problems with it! 700 rounds so far (and then I cleaned it!).

I'm assuming that was a typo. They sold for like 1500. retailers bumping the price for covid still leaves it under 2500. Once you contextualize the issue, it was still worth 1500.

They expect the consumer to pay to do their testing. We’ve seen it with the P365, 322, MCX, Cross and more. It’s ridiculous to pay 1000’s of dollars for their untested products.

[@chrisclark6161]

@@roul3688 That would be retailers and private sales asking 2,800 due to covid/election panic. Mine was 1500, which is a fair price. Also, I completely understand wanting to bash sig for truely fucking up a lot of stuff. But this isn't a strong case for it. This is an example of being too bash happy. It's an issue you have to deliberatly find, and a very minor one at that. It's also not unique. Early ARs recommended draining the barrel after submersion, and it's standard practice in the military to eject the round and drain the barrel to this day.

[@roul3688]

@@chrisclark6161 Maybe it’s just me, but I would think that before selling a military grade product, likely initially designed for the military, they would’ve dunked their gun into some water during their testing... that is of course if they test beyond firing 3 rounds.

So is it fix bro? I bought mine around the same time

[@FryedGamingNet]

This was a question I did not know I needed the answer to.

[@BP-in3lt]

I think I finally found out the reason for Sigg’s Unreliability issues: The people at sig. do not know the difference between 1 billion and 1 million. This was from the email that touted the millionth P365 but show the number “1,000,000,000th p365” displayed underneath picture for the article that reports on the millionth P365 born this year.

[@PBVader]

Another one for the team.

[@ChristianGrest]

Sig called you? Might wanna play the lottery! But seriously, good on them to admit the issue and send a gun to test. I wonder if Sig will offer a repair service/update service for the older models?

[@michaelecarvell2958]

MAC you and your family have a Happy New Year and hope 2021 will be a better year for everyone especially law abiding citizens to keep all sorts of weapons

[@cfreeman9601]

Sig may have messed up not figuring this out in more depth of some of their firearms. I own several SIG products and never had any issues with them and also SIG is literally like the only company that is actually coming up with new designs/products than any other company out there. So in some sense there will be issues with new products they make, but that comes with making new things.

Got those same gloves you've been wearing lately, except in more northeastern color. Good ol' Cabela's

[@project86xero]

Makes since. From a fluid dynamics standpoint water likes to drain better out of a non symmetrical hole. Perfect circular holes, especially smaller ones, not so much. If it was just the round gas port hole on its own it would drain as long as it could flow out somewhere else. However if the only way out for that water is another small round hole it's easy for it to get held in due to surface tension.

Good on sig for being honest

[@patrick-hn8fh]

Great Sig I’m glad you can send these out to people and I’m glad your fixing issues now could you just sell them somewhere or nah? Haven’t been able to find one that’s not price gouged online in forever been waiting to buy for months.

[@andriy_moskalyk]

Great vid, please do more on sig mpx

[@bryankim2277]

Do the gauntlet with the new MPX. With the slot, doesn't it change the chance of debris clogging the larger gas hole?

[@bobbymalcich63]

HAPPY NEW YEAR TIM AND YOUR FAMILY!!!! GREAT VIDEO TIM!!!!! KEEP UP THE GOOD WORK!!!

[@Dr.Tackleberry]

Tim. I love you. Awesome video brother

[@refan6]

Good info. Can’t wait for an updated Stribog video with the US bolt and new mags with black followers

[@El_Taco72]

My 3 year old gen 2 eats everything I throw at it. I’ve been very happy with it.

[@Ron5topable]

Great follow up! Thanks Tim!

[@Militaryarmschannel]

Thank you and Happy New Year!

[@RexNicolaus]

Sig is a nice brand... when they fix the issues months or even a year down the road.

[@nelsonr1467]

Yet people think they are somehow better than glocks

[@codeofreliance741]

I totally get it- and its great that Sig made those corrections- but I shall leave you with this.... 2020: Buy a $2k PCC, pour water down the barrel, fuss about having to preform immediate action. I propose for 2021 that we buy a $2K PCC, and pour maple syrup down the barrel, and complain about having to do immediate action. You know for science, and stuff. Any and all weapon systems will fail at some point - and Im no ninja, be able to get your firearm back up and running. This isn't a knock on MAC, he is doing great prudence for the firearm community - but seriously - we will literally find anything to complain about- haha.

[@spacedcowboy11]

Love my MPX... though now I need to check my gas block, just because.

[@NC_USA_Gunner]

The peening on the inside of the receiver is a well known issue. I have the same in my MPX. Apparently, well known among PCC competition circles; I was made aware by a neighbor that has 2 MPXs for competition. I believe it has something to do with BCG materials and geometry. If you report it to Sig, they'll have you send it in and you'll end up with a new upper and new BCG components to fix. Only reason I haven't done mine yet is gun still shoots well and haven't been in the mood to be without the MPX for 2-3 weeks.

[@Militaryarmschannel]

After filming Jason did some digging and discovered this is, yet again, a known issue. Thanks for the post and Happy New Year.

[@fishman80]

great Job and update Tim. I dont even own the gun, but always love these videos. thx

[@Militaryarmschannel]

Thank you Jimmy, and Happy New Year!

[@jjpenny1384]

Might get one now. Thanks

[@cgtlea9202]

I just picked up a new MPX K that was built sep 2021 and the upper receiver has slight alterations than this generation. There are only 3 vents in the handguard above the barrel and the left side of the firearm no longer says MPX on the upper and there has been some alterations made to the two screws that hold the ejector in place

[@keithallardice6139]

Much appreciated

[@knighthawk6633]

WARNING - read before you purchase. Test your ILWT barrel to ensure that ammo feeds correctly. Mine did not because of a high feedramp. ILWR is 0.060” compared to the OEM 0.035””. The higher feedramp resulted in bullets nose diving into the base of the feedramp and not onto the feedramp resulting in stoppage. Because I let the gun sit in my safe for a year and did not identify and report earlier, ILWT won’t work the issue and I am required to make Dremel modifications to correct the geometry of the feedramps to allow seamless feeding and function. I highly recommend identifying the issue early and brining it to ILWE’s attention or else you too will have to break out the Dremel.

[@jayzhao1817]

Interesting video, after watching it I took mine apart.. my gas block did have the longer vent, so it is gtg :) bought earlier this year, not sure when SIG made the change.

[@Militaryarmschannel]

Awesome! Happy New Year!

[@createvii7886]

Thanks I love the gauntlet tests.

[@unklemike5012]

I'll stick with my Scorpion EVO. Cool video. Always neat to see how things get fixed.

[@williamflowers9435]

Shouldn’t SIG offer to replace or send out the new gas blocks free of charge upon request? Seems like the fair thing to do considering the price

[@tteot1wph]

Yep

[@KM_1983]

Even if the do the "voluntary upgrade program" thing they did with the 320 it would be ok.

[@wendellsawyer4386]

Why?
