Hollowpoint: The GM wouldn't happen to be in SW Lower Michigan, would it?
I bought an M&P9 a couple of weeks ago after several months of looking at various makes. My opinion of 9mm wasn't very high based on the Beretta' my rich uncle decided his nephew's in green suits ought to use. It wasn't as good new as the beat up, older than dirt, mistreated like a red headed stepchild 1911 assigned to me. The M&P felt better than the XD and Glocks I looked at. My only experience with S&W 9mm was a few rounds with a Sigma and a few rounds with a 5906(?). The only use I could see for those was to get enough to make up a good boat anchor weight. The High Point C9 felt better and shot better than either of those.
I haven't seen any mechanical problems in the few hundred rounds I've fired from my M&P9. I like the way it feels when I shoot it. The adjustable grips are a plus. I put ammo in it, rack the slide, point it down range and pull the trigger and it goes bang without fail. As long as I don't use the Fioochi ammo I bought with it, it seems to shoot very consistently.
I do have a few negative impressions of the pistol I bought. Although I am by no means an expert marksman, the M&P has taken more rounds at shorter ranges to get POI where I want them than other 9mm's I've shot. I think it may have uncovered a flaw in my shooting. Also, the M&P is probably going back to S&W. The pistol seems to shoot low and left. The front sight is not centered. No idea whether this was intentional at the factory or not. My impression is that my $175 22A-1 was better out of the box than the M&P. However, the gun is nice enough that I'm going to spend more time and ammo to convince myself that it is the shooter and not the pistol before it goes back to S&W, a smith, or I start whaling on the sights with a hammer and drift.
