Both generations can use both mags but with varying reliability results. My Gen I gun used Gen II mags flawlessly. My Gen II cant use Gen I mags if using JHP ammo, but will feed FMJ without issue. Reports vary. The short version is that results are dependent on your particular MPX and the ammo you're using.

Thank you for the heads up on the mag compatibility. I doubt I'll find one used but it would be nice to pick one up for sub $2,000.

This writeup answered questions I didn't know I didn't know. Well done & thank you.

In what way is it an improvement over stock?

I can see that and don't consider that an improvement at all, that's why I asked.

I prefer stock to that thing.

I know. It was sarcasm lost in translation. I agree the big handle is needless.

I seem to recall there was an issue with the MPX charging handle, where if you pulled both sides simultaneously, it would fail to unlock? Maybe this remedies that, since the MPX can't accept standard AR charging handles and no one had created a fix due to the proprietary nature. Just spit balling.

Well, mine doesn't have that problem and neither do the 2 others friends of mine own.

Coolio. Must've misheard. If I can find the source, I'll post it

I’ve been using the Next Level Armament CH on my old MPX carbine since soon after I bought it back 6 years ago, so there are aftermarket alternatives.

Okay, don't flame me for posting. I don't have an MPX, although I'd love to pick one up, but this is where I heard the above re: charging handle:

https://youtu.be/kuOI0sfKD1w?t=160

Obviously this is a sample of one, and not necessarily indicative of every iteration. But when someone posted the "improved MPX CH", in the back of my mind, I thought: "Oh, they could possibly be addressing that weird issue I heard about a year back."

Sorry if my post ruffled any MPX owner's feathers.

I got an email from my Sig rep. They have started taking pre orders for a new 35 round MPX magazine with stainless feed lips. Looks like MAP pricing will be set at $36.99

I'm not flaming you and this is the first I heard of this "problem".

So I pulled my MPX out and tried to get the failure shown in the video and it didn't happen. Mine works perfectly as is.

I talked to my two friends who have MPXs and had them try, and they had the same results, which is no problem whatsoever.

We've all got Gen2 MPX's and we all have 8 inch barrels and we bought them all in about a 4 month time frame.

So at least one, the one in the video, has a problem and at least 3 don't have the problem.

And the video said theirs was the Gen 3 and that may be the solution to the quandry. Gen 2 doesn't have a problem but Gen 3 does...maybe.

It was probably just a one off or rare issue. I did not investigate, as I haven't been in a position to purchase. My mistake.
