I have about 800 ish rounds through my SAM commander 9 mm and have had no real issues. Blazer aluminum clogged it up and it won't feed the first round of 147g if I load the mags with 9, but 8 is no problem. Just a bullet shape, spring tension issue. Had a minor issue today with it extracting but not ejecting the last round in the magazine occasionally; but judging by the amount of crap I cleaned out of the extractor, I think I took care of that. Never caused a big problem, the last shell just fell through the mag well with the magazine.
Wolverine just got the full size 9mm stainless back in stock and I'd be all over it but I hate sleeping on the couch. You wouldn't be disappointed.
