MPA 930 Mini 9mm
I picked this up the other day in a trade as a fun gun and it did not disappoint. Literally a "blast" to shoot. It uses Sten mags but it came with two poly mags that really work well. I ordered a couple of Brit converted 20 round Sten mags for it as they are a bit shorter and very dependable. No issues (other than a bit of trigger slap) so far with the weapon but I've only ran a few mags through it. Does anyone else out there have one?

I had two of the fullsize(should have kept them)but I still want the mini.Nice score.
i got the full size mpa30 9mm. great range gun and very fun to shoot, and shoots more accurately than most of my other pistols.
I've got one of the full sized ones I picked up on a whim too. Horrible sights, terrible trigger with bad trigger slap, ergonomics made for a retarded ape and ridiculously heavy especially with a full Sten mag. It still puts a goofy grin on my face when I shoot it, starts conversations when people see it and has been 100% reliable with everything I've fed it including some crap South American ammo. I haven't shot it in several years now, but I may have to change that next time I go shooting.
ETA- I've never used the cutdown Sten mags, but a loader will make your thumb much happier. They get to be a real pain getting them full.
When your sten magazines are fully loaded do they lock in?? Mine wont lock in until I pull back on the charging handle...
It's been a while, but I can't recall mine having any issues with any of the Sten mags I have even fully loaded. The mag themselves are a pain to load without a loader though.
