I jumped in skeptically on my purchase of the PM9. I wasn't a PM9 fanboy or anything. I just wanted a small pistol that I could keep on me concealed while at work.
I was actually about to buy a S&W 642. Now THAT I can say I'm a fanboy of. Mainly because it's a revolver and I believe revolvers are reliable as they get. It's small, relatively inexpensive, hammerless, and just plain legendary.
But last minute, I decided to buy the PM9 when I was told that a nearby store had one in stock. I appreciated the fact that it's smaller and slimmer as well as being able to use 9mm ammo. And since it's a semi, I can carry an extra mag and reload a bit quicker. Not to mention that it held 6+1 in the standard mag and 7 in the extended mag vs 5 in the J-frame.
But the 9mm really won me over on the decision. I really believe that shot placement is key but a 9mm is a much more destructive load. And being able to use ammo interchangeably with my other 9 made it an obvious choice.
Before I ever got to shoot it, I read a lot of stuff online and mine was a newer batch with all the bugs worked out so I didn't expect any problems but everyone and I mean EVERYONE said that I need to break it in for at least a couple of hundred rounds and during those times, I'll definitely have some FTF or FTE.
Well, 500rds later, I still haven't had 1 failure. And with the smooth trigger, I shoot almost as well with it as my fullsize USP. I think at 7yds I shoot 1" groups. At 11yds, maybe about 1.75" and at 15yds, about 2.5". I couldn't imagine ever needing to use the PM9 at a greater distance than that.
Now that the .380 version is out, I'm really reevaluating my opinion on minimum effective caliber.
