Early adopter. Nice gun, reliable, decent ergonomics. Suppresses nicely. Mags are stupid expensive, it’s heavy.

I have the 16" MPX PCC and it's been great.

I did swap out the Extractor Springs with some from In Lead we Trust and it's been 100%

I put an AEMS on top and it's really fun, it's my kids favorite gun to shoot.

Yes. Just got my SBR approved a couple weeks ago.

Current gen mags from Thril are not expensive. If you buy their mags (they are OEM) and not the SIG branded mags. You can find them online for around $24 a piece. Now the original mags made by Lancer are stupid.

I have the MPX copperhead (the one with the threaded barrel). Mine has ran fine, but I’ve not shot it very much (less than a few hundred rounds). I SBR’d mine. As others have noted, it is heavy.

Only complaint with mine is the accuracy isn’t great. It works well enough for my PCC needs, but it’s something to consider.

I've had the 8" for years. Swapped the rail out for a Midwest to sink my Omega 9k under, been shooting a Geissele SD-3G in it for 6ish years without a hiccup. It's been great and a lot of fun.
Recently got my SP5 setup the way I've been dreaming about since I was a kid so the MPX has been taking up space in the safe for a while.

I like it still. It’s just different.

I got one years ago, never had any accuracy issues like some others have. It's been modified a bunch and is a 2 stamp gun. I love it, but it's a very expensive, heavy pig! I'm keeping an eye out for a Stribog SP9AS or something similar for lighter weight.

I carry a gun because a cop is too heavy.

Mags from Thril (the current OEM) are around $25. Not that bad.

I have 2 of them in the 8” configuration. Probably my favorite PCC other than my SP5. Ergos are way better and it’s a great gun to use for new shooters

Had one of the 4.5" models with almost 3k through it, most of which were during a three day PCC/sub-gun class. It was solid, never gave me any fits. But, my want of a legit HK SP5 eventually saw the MPX get sold.

SBRed mine years ago. It’s been rock solid and suppresses well. Accuracy isnt great, but it’s a lot of fun to shoot. I didn’t like the original collapsible stock, so I put an AR-style stock on it which I like much better.

I like my SP5 better, but mostly because it’s lights-out accurate in comparison.

ETA - I said I like the HK better, but I still have a lot of love for the MPX.
