The new Sig MPK-k 9mm pistol looked to be very promising. Jason decided to get one from a local dealer and trade me for my older gen 1 MPX since he knew I would want a shorter barrel and he wanted the longer barrel and access to the inexpensive gen 1 magazines. We ran into a problem.

The same exact literal thing happened to my Sig MPX-K that was manufactured 9 May 2019. I had shoulder adapter and In Lead We Trust trilug adapter and it throws rounds everywhere with and without Ti-Rant on. What are options, to spend a bunch of money and get an 8 inch barrel from either ILWT or SIG actual and take a chance on it not working.

[@Militaryarmschannel]

You're not the only one. My friend sent me a text message after I released this video telling me he bought a MPX-k too and like me, his shot all over the place with his SilencerCo tri-lug and silencer. live.staticflickr.com/65535/48180251001_4e198726c3_b.jpg It may be more widespread than I thought.

[@jackal2001a]

Same thing with me. Tried a bunch of barrels. Nothing helped except going to an 8".

[@JB-mv1fn]

I get on the phone with SIG and they say to send rifle and if it passes their spec I will have to pay, but he can’t describe to me their standards or what is in spec. BLUF, if I can’t take a sub gun and hit an obscured target behind something I don’t want to hit, it is a paper weight right. On top of it is 1700 dollar gun that should be working. Thanks for posting this video because I have been looking on internet for the last 3 weeks trying to find somebody with this same exact issue.

[@Militaryarmschannel]

@@JB-mv1fn ...and that's why I don't deal with Sig's customer support. I bought one of their early 1911's and it went full-auto on me in an indoor range (the store I bought it at). I called Sig while at the store and they told me it was likely the ammo and the gun wasn't broken in yet. LOL. I let the guys behind the counter hear the conversation. Needless to say they took the 1911 back and I picked something else up.

[@JB-mv1fn]

jackal2001a what specifics on barrel you got. I was basically going to go with ILWT with the trilugs on the barrel, which to be seems like a better option to begin with.

[@mikeg7363]

The problem is actually the Griffin 3 lug adapter. I went through a similar trial and error process couple years ago with my gen2 and three new adapters. Griffin's MPX metric adapter indexes on the muzzle, which is correct for metric threading. But when torqued down too much, the muzzle crown/adapter interface inside is warping, instead of being an absolute solid stop. The issue is either 1) the steel material Griffin used is too soft compared to the barrel, or 2) the manufacturing of the adapter is not up to official 13.5x1LH specs (interface circumference area too thin). Shine a flashlight inside a used adapter and you'll see the interface edges deformed/ragged. The Sig barrels are actually fine and the threading is true. If you direct thread a silencer using a normal quality metric piston, you will find that it easily shoots same-hole accuracy. The tapered barrel is unfortunately an inconvenience as it limits other options that could utilize a squared shoulder. I would not trust a trivial slip-on doughnut adapter since we can't confirm if the outside taper was designed concentric with the bore. Even if it was, there's still tolerance-stacking risk in play with slip-ons. I just gave up on the 3-lug system altogether (sloppy standards anyway) and stuck with trusty ole direct thread on the MPX.

[@austingreen3888]

The Griffin adapter preceded the taper muzzle system. It works on other 13.5x1LH guns. We have some customers that had good results with the Sig barrels, others that didn't. It's hard to know what isn't working when the Sig product isn't consistently interacting with the parts. My guess would be the device sometimes bottoms on the taper, and the MI taper shoulder ring isn't square. We make one of those rings too. Ours has 100% of the datums cut on the main spindle. So they are square to about .0003" which is as accurate as can happen in modern manufacturing. It's not ideal to have to retrofit a shoulder. The Sig tapered shoulder isn't good for that reason.

But planned obsolescence was something Detroit was into in the 60's and 70's

[@stever8776]

@Thystaff Thywill So Sigs poor quality is because of tariffs? Sig started making some of its guns in the USA because of Germany's export restrictions. Germany restricted the types and where the firearms could be exported. US manufacturing gave them a loophole. FN has no problem with quality control in their US facilities. Beretta had to produce M9s in the USA to get the Army contracts and had no problems other than the original design of the slides. They have no problems with quality control. As to tariffs, When the the Constitution was written there were very few sources of revenue i.e. taxes. Tariffs were one of the few sources of taxes. Tariffs were also designed to protect and encourage local production. Excise taxes were another source. Remember the Whiskey Rebellion. I think you are confusing the taxes on the exports of Southern Cotton with Tariffs. The South was angered US was using their major source of income to fund the Federal Government. But WTF?

Taper mounts are a good idea when done right. Just as with squared shoulders, if done wrong it creates problems. For example, I built a rifle for a customer last year that mounted a Faxon barrel. It shot MOA with a muzzle brake in place, but the bullets would not even strike cardboard when a suppressor was attached. No amount of tweaking or machining would fix it. In the end I sent it back to Faxon for examination. They determined the muzzle threads and shoulder had been cut slightly off center and could not be made concentric. Their replacement barrel worked great. Sometimes you get a lemon. In the case of Sig it's a question of whether they are producing the odd lemon or making lemonade.

MAC the only thing I can think of that is causing the shot desperation with all of the muzzle devices tested is the barrel threads are not concentric to the centerline of the bore.

When you have the spread of a cap and ball, something maaaay be wrong...

[@outsider1810]

I bought an mpx off a guy who had the barrel cut to 4.5 inches and threaded to 1/2x28. Suppressed it with a liberty mystic x. With 115gr ammo it shot 6 inch groups at 20 yards but 2 inch groups with 147gr. Ultimately I replaced the barrel with a 4.5 inch barrel from ILWT and I easily get 1 inch at 20 yards regardless of the ammo and regardless if I have the can on it or not. "Gen 2" btw

[@chassoto]

Clearly, there is nothing wrong with the "pistol." You're using the wrong muzzle device(s) for that particular gun.

[@XPsychowaffleX]

That is the most asinine excuse I've ever heard. Suppressors arent made for ONE gun. And making a gun incapable of using anything BUT one suppressor style is not only pretty sleazy, its playing your customers for suckers when you claim they will still work anyway, or tell them to buy more shit to make it work. Like apple. Only apple could take away features then sell them back to you as "accessories"

[@beardoggin8963]

BuhLakeh exactly. That is the kind of treatment you get from a complacent company. Seems like Sig is riding the million off of the government contract and is selling customer “whatever” they throw together.

[@bbllaakkeeee]

You both are absolutely dense. If he takes the mount off and there’s no issue, then it’s not the gun. Maybe you should look at a reviewer that has enough common sense to DA the suppressor that’s meant to be on the weapon system.

[@freedoomed]

I would also recommend making sure the barrel screws are properly torqued down. my MPX out of the box was a bit loose after the first range trip.

[@Militaryarmschannel]

Checked. It was the first thing we did when it started shooting all over the place. I keep a Fat Wrench in the Jeep.

[@TheJbower76]

Ron Cohen came from Kimber. Once good brand that went to crap. Ron Cohen goes to Sig.....Sig going to crap......see a pattern ??

[@freedomgunsandliberty]

I'm so glad I didn't get a sig pistol for my edc pistol. Their quality is hi point but their price is top shelf. You cannot live on your company name for long if you're consistently putting out garbage. Sig used to be a solid performer and has really let thierself go.

[@lucasmcculla1283]

Sig use to be a good company..bought three products that all failed..sig new Hampshire is a joke..polymer Japanese junk...cooked a romeo5 on a m92 (gas tube mwi rail mounted) on a 91 degree day...4 mags n dot went out ...that was the last straw..never by sig again unless it's an old school German made...

I'm using a direct thread can with no problems. This is interesting for sure and good info to have.

with a 1/2 -28 thread adapter on the direct thread.

[@Militaryarmschannel]

I don't run direct thread on silencers because they back off while shooting and cause all sorts of issues.

[@BillHesse]

@@Militaryarmschannel indeed that is a reason. I only use mine for limited night shoots for hunting so I can see where you are coming from. I was just adding experience with that particular method.

[@skyskippr]

@@Militaryarmschannel Wouldn't a direct mount, left-handed thread, tighten as it was used? I suppose you could still have carbon build up on the barrel threads over time, and possible carbon lock? Beside those issues, one benefit to direct thread is it keeps you total package shorter... ;)

[@donovan007007]

When did anybody think that Sig made quality guns?.... Hahahaha

[@CatMan_7]

Tim, looks as though you have a true life Gremlin there. I had one on my SPAS -12 I picked up in ‘92. Tried everything but it wouldn’t semi cycle at all. At least they exchanged it for in store credit.

[@paintballers1121]

Still cant believe the novice level of testing. There are so many errors it's not even funny. You could simply have a small peice of carbon in the 3 lug mount I challenge you @militaryarmschanel to send me that exact 3 lug adapter to inspect in a machine shop inspection room. I also am a FFL and SOT. You prove nothing other tha. There is nothing wrong with the gun as it shoots the smallest group of all with no muzzle device at all showing there are only problems with your muzzle device. Ill send you a copy of my ffl and sot if you send the upper and 3 lug and I'll give you and aerospace accurate printout of the actual readings. And for all the clowns claiming how their cz is so far superior I cant help but laugh. Mac I hope you take me seriously and consider this

[@m.c.clap-yo-handz7632]

My Gen1 has the same issue. It only happens with a trilug though. I used an Osprey with XL piston and barrel spacer and the gun shoots perfectly. I think the issue is honestly the tri lugs. So I don’t use it anymore. I use direct thread Osprey. Looks stupid as hell, but it shoots right groups. Now I only use tri-lug for my Zenith MP5. That thing shoots great with any can on it.

[@Corpsealot]

Looks like an issue with the threading. Buddy of mine had the exact same issue on his AR barrel. It was weird.

QUESTION! Is anyone else receiving Tim's video upload notifications? I just realised I haven't seen a notification from this channel in maybe a month. Subscribed and have the bell marked.

[@kairandson4886]

[@Militaryarmschannel]

Kai Huso You can try hitting the notification bell might help. I have lots of people say they don’t get notifications.

[@Ruweisat]

Between this & the PSA AKV, you have either a habit of getting lemons or exposing design flaws.

[@Militaryarmschannel]

PSA fixed the AKV and even named the fix the "MAC Bracket". So yeah, there was a problem and they quickly worked to resolve it. How many other channels reported the same issue with the design that PSA acknowledged and fixed?

[@garrettsayger1275]

I have seen tri-lug adapters produce these results on mp5s. The best way to test this is to try a direct thread suppressor. I’m not a fan of Sig, but this seems like Tim is on a war path with Sig. regardless, he could avoid that appearance if he did what a lot of us are suggesting: try it with a direct thread suppressor.

Sounds like there’s a market for tri-lugs that will index on sig taper barrels. Maybe you could call Hanson Bros and see if they will make one for you to test.

Sig has always been shit since they started domestic production. If anything, they are actually getting better the recent years.

[@mauricemaurice123]

[@Scientist_Salarian]

Even worse, they got the massive MHS contract. Once you get that guaranteed government money, quality always drops for the civilian goods.

[@AICW]

@@Scientist_Salarian Beretta products were just fine after getting the government contract aside from the first five years or so of the M9 and its issues.

[@URBANAMERICANTAC]

My god, my MPX is doing the exact same shit with the same tri-Lug and shoulder adapter. I even got a 14” group at 25yrds. My B&T ghm9 with the 4” barrel and tri-lug adapter is a little tack driver. This MPX I bought is absolute garbage. Sent it into sig, they sent back 6 targets with 1” groups at 25 meters using 115 blazer. Didn’t do anything to it. I bring it home, strap it in a lead sled and shoulder it and it’s best group is 5” with the A2 and several different bullets and weights. Worst group, 14”. Insane. Im going to try the 8” ILWT barrel.

[@Pacheenee7]

Try the Stribog

[@lpanades]

With the longer barrel gun you have more space to use the barrel like expansion chamber. That guard can fit a suppressor inside. You just need a shoulder near the begining of the barrel to hold the suppressor. You will get much better results.

[@Tadicuslegion78]

This is what you get when you hire a bunch of people who don't take pride in their work in ensuring the best firearm quality control and instead just pump out as much as you can as fast as you can to maximize profits.

Creed Bratton must be working for Sigs quality assurance now

[@ricallen7273]

Chevy has proprietary tools and fixtures. Ford has proprietor tools and assemblies. Dodge, etc, etc Sig works great with Sig stuff. Not good, not bad. Just is

[@killervztwogaming5796]

M13.5x1lh doesnt require a shoulder where the threads end. it shoulders at the end of the barrel, AKA where the threads start. hence why a taper adapter is not needed AND why it is making your shots go wild. you are not allowing the trilug to seat properly.

[@KGiustOD]

My money is on the barrel geometry right before the threads. As soon as you mount something on there, it throws the harmonics or stresses the barrel and it throws the shots. Threads that aren’t concentric shouldn’t change anything when you mount a flash hider.
