I've actually heard this complaint from multiple people. Admittedly it is not a huge number but I tend to put more stock in reports of people I can talk to than simply internet videos or chatter. I have seen conflicting reports on the issue from some online sources. Also different cans can be better or worse in that regard. Some people seem to suggest it is worse than a number of other guns in that respect. Some suspect it is a result of the self regulating gas piston that the gun uses. I don't know about all that but I am interested in hearing from as many actual users as possible. I'm in the market for a 9x19 SBR but it would probably be shot suppressed most of the time so if it is as bad some people have suggested that it kind of a turn off and might push me in another direction.
Does anyone buy one without the intent to make it into an SBR? If I had one in it would be an SBR as soon as I could get a stamp.
What other ARs and cans have you used? I'm trying to get a point of reference for your comment. What makes you think it would be the same. It is a different operating system.
How many rounds do you have through it? How have you used it? What about it impresses you? It is on the list of guns I'm considering for 9x19 SBR. I'm seeking all the feed back from actual users I can get. On paper there is a lot to like. However, real world can be different from paper. And Sig has not inspired a lot of confidence in their recent rifle releases.
Thanks for any feedback you can offer.
As stated in my earlier post, it will be probably a minimum of 4 months before my stamp comes back and I can take my suppressor home or to the range and shoot it on my MPX. Today, I shot 200 rounds through it (un-suppressed). Most were 147 XTP’s, and about 50 Montana Gold 124 hollow points.
The 147 XTP is the bullet that I will use for home/self defense (or something similar). It will be a decent quality 147 Hollow point jacketed bullet of some kind, i.e. Speer Gold Dot, Federal HST, etc. Today, the goal was to get those XTP’s zeroed at 25 yards. That yields .75" low at 50 yards, and 3.5” low at 100 yards. That is about my limit with a Red Dot Sight but, the bullet is still moving at over 900 fps at 100 yards. Not bad and pretty good point blank range out to 100 yards.
The guy I saw whining in one video was NOT shooting suppressed and he was comparing the MPX to the EVO. He admitted he was trying to find something negative to say about the MPX and the gas “issue" was all he could come up with. Still he shot 500 rounds through it, out of the box, with no issues and no failures of any kind. He was in an open field. Today, I was at an indoor 100 yard range, benched up, with a sheet metal partition 8 inches from the ejector port and my face. Not a single sparkle. I can say emphatically, there are no “gas” issue without the can. It will be a while before I can report about the suppressor. Sig says not an issue.

I have flied the Form 1 and backordered the stock. But, in some of the Commie states, it may never be legal. One nice thing about this setup is that if you ever have to cross one of those states, just take the stock off. It is now a pistol (and way safer).

About 500 rounds. All at the range. No shoot outs or raids to date.
Zero failures. Eats anything I feed it. Excellent accuracy with any quality ammo. I can shoot clover leafs at 25 yards and I am not that good. Stays accurate even when the gun gets hot and dirty.
Break down (including barrel and gas block removal) takes less than two minutes. Easy to get sparkly clean in a matter of minutes and back to the races. All metal, fit and finish are superb. Ergonomic are just like an AR but with ambidextrous everything. I like the Lancer magazines way better than the Glock, You don’t need a loader to load 30 rounds quickly. Just push straight down and the cartridge clicks into the mag just like any good AR mag. With a little practice, you can load 30 rounds in about a minute.

I have used M16’s, M-4’s, and to a degree the, MP-5 when I was in the service and or working in LE. I have owned some form of a civilian AR-15, or M-4 since 1982. I have only owned Colt, Noveske, and Larue, in that order. Never had a Sig rifle, so I can’t comment. My Sig experience is limited to P226/P229 pistols, and to this day, is my favorite double stack auto. Fit, form, function, performance, reliability, its all there, just like the MPX.
I currently have a Colt LE6920, Noveske M4 in 300 BLK, and a Larue OBR 5.56. I have an AAC SDN 7.62 for the Noveske, and a Surefire SOCOM for the Larue and Colt. The Larue has a "switch block” for shooting suppressed, the 300 BLK is designed to run without one, and it sucks to shoot the Colt with a can on it. Think pizza face.
I wish I could compare this little SMG to others but I have never owned anything like it. I will be hitting the field with it during November and December for some mock up 3 gun tactical style stuff. Looks to be fun but, I won’t have the can by then.
What else are you thinking about getting? This thing seems to be a new and improved version of the MP-5 in civilian version. I am not really sure what could be “better”. Cheaper maybe. I don’t know.
Other cool things coming:
- 357 Sig, and 40 S&W barrels
- Forarm length is easy change out to cover all or part of suppressor.
- Comes with 3 mountable 1913 picatinny rails for accessories and an additional Single Point Mount.
The worst thing I can say about the MPX so far is that the trigger could be better. It is not the worst trigger on a factory gun I have ever owned (that would be Colt) but its not good either. I’m going to call Sig tomorrow and see if the Geislele is an approved replacement.
