That is the original configuration that sig intended to release, but it was not made available to the civilian market due to the ATF deeming the 9.5" muzzle brake as a suppressor part. The new carbine version that's as been released is a 13.7" barrel with a 2.3" flash hider (from what I read).

A Sig employee who goes by Coregon on AR15.com has verified in a thread on the MPX that the KeyMod versions are indeed Gen 2. In addition, it was revealed that the differences between the two generations include the following:

Gen 2 have the KeyMod hand guard, grooved top picatinny rails, larger ejection port, longer bolt carrier, and different barrel extension. The part number on the Gen2 MPX-P is SIGMPXP9KM MPX P 9MM 8. I jumped on one of these for $1275 shipped.

Of note, the Gen2 barrels will not fit in the Gen1 guns. That makes me wonder if Sig will make 4" Gen 1 barrels for those who want a shorter barrel to suppress under the hand guard, or how long they will support 8" replacement barrels.

SIG really is annoying me with the MPX. If I can't buy a replacement barrel for my MPX Gen 1 I'm going to be steamed. I am shooting the hell out of this gun and I can see a replacement barrel need after a few years.

It's a good day to be an American!

My telescoping stock arrived, and now I can remove that extra piece of foam in the case!

Congratulations man! That looks very nice and it's been a long time coming, I know. I had plans of doing the same with mine but I think I'll hold off on the NFA hoops until I see where Sig is going with rectifying the generation 1 caliber exchange issues.

Thanks!

The good news on the NFA front is that the lower is the serial numbered part, so even if you swap in a gen 2 upper, you should still be fine.

You are correct however my concern is not which part must be registered. My concern is the money I'm spending. Kind of reminds me of a used car that has become a money pit. When do you decide to scrap it and buy a new / different car. I currently have about $1900 in this gun. If Sig would offer an upper exchange and not a "deal" on a gen 2 upper, I will stay interested and loyal. Just very disappointed. I have been a loyal customer of Sig for over 15 years and own over a dozen of their firearms. I truly expected better. Please forgive my rant.

AWESOME. Now go to the range and post a report!!!!

I haven't seen any mention that these second-generation guns have any fix for the charging handle issue. Any news on that?

Funny you should ask, I just played with one this morning and was going to report back on that. No unfortunately the charging handle droop is still an issue. Were it not for that I would have ordered one today.

What Sig CS told me was that we could buy the upper kit which is around $1000.00 and probably a 20% discount off that, so yea big discount there. Sig needs to swap every Gen 1 upper out for those that wish to do so as they were very sneaky getting these Gen 1's sold thinking we could change the caliber and now we can't. Can't even change the barrels unless they make Gen 1 short barrels (4.5") but I dought it. Pretty shitty if you ask me.

I'm kind of confused by you guys whining about Gen 1/Gen 2 "issues". It was explicitly stated on multiple websites that the Gen 1 guns would not be multi caliber. You knew that going in. If you wanted a multi caliber gun you should have waited for all the issues to be worked out and then purchased a multi caliber Gen 2 gun. I only wanted a 9mm gun so I bought a first gen gun and couldn't be happier. IMHO Sig owes you guys nothing. But like I said, it's just my opinion and you know the old saying...

That was helpful. Assumptions have an old saying too.

What was an assumption? The information was out there. Sig was not hiding anything. They explicitly stated why the MPX was delayed to begin with and explained how and to what end it was being released. How are "Version 1" owners owed anything besides a "Thank you for your purchase!"

BS. Sig might have said no caliber conversions on the Gen 1, but they did say different barrels and now they are saying the other barrels will in only work in Gen 2 uppers. You really think they are going to make Gen 1 specific barrels? No they aren't, so again, it's BS what Sig is pulling.

Your post contains opinions (yes, we all can agree the old saying is correct), facts (a link confirming Sigs release announcement) and then assumption (you stated the "whiners" knew these facts). If you can convince me you have spent time in every "whiners" head and know this statement to be fact, I will apologize. Look, you're happy with your purchase and I'm sincerely happy you're happy. Some people are not and for a variety of reasons. You calling disappointed Sig MPX customers whiners is not cool and doesn't correct or help their disappointment. You further telling them what they should have done is not helpful either.

I probably won't even shoot anything other than 9MM from my MPX, so I don't whine a lot about the caliber change issue (though I still don't like it, since that was the original design spec).

But I'm sure not stoked about a charging handle that scars my lower and chips my upper, and that still didn't get fixed in Gen 2.

I agree with you there and feel that issue is a legitimate gripe.

And so are the barrels. Maybe I want a 4.5" barrel for my Gen 1, which isn't going to happen unless I cut an 8" which I should not have to do.

I don't think it was out there as widely as some here imply.

What little I knew about the MPX led me to believe that one could swap out calibers and barrels on the gen1 guns. The guy at the LGS even used that as part of his sales pitch (not that one was needed).

Did I do enough research? Obviously not..but than again my free time is limited and I simply can't read everything.

Ultimately the caliber conversion thing is not a big deal for me as i don't plan on shooting anything but 9mm, but the lack of a replacement barrel is an issue.

Sig advertised them as being able to swap calibers, even on the printed material. Not everyone reads these forums, in fact I would bet most do not.

The barrel issue is still in flux. All we know so far is that the Gen1 and 2 are not interchangeable due to the barrel extension. Sig has made no announcement as to their support for the first generation. We may find that it is a non-issue if Sig supports the Gen1 with a variety of replacement options, or if the barrel extension is swappable.

Honestly, I think this is a great opportunity for guys with industry contacts like LDD to bring this feedback to Sig and get their official answer.
