I have a full size 9mm, thumb safety (only on one side), Crimson Trace with Warren Tactical Night Sights. I'm currently taking a Tactical Pistol Course. Our first range day we fired over 600 rounds. The pistol was brand new out of the box. I cleaned it before beginning the course. Not a single problem firing all Winchester White Box 9mm ammo.
I did have to get used to the trigger and trigger reset. I had been firing 1911s so a big difference in trigger. The guy beside me was shooting a 1911 and I can tell you it was nice to have a few more rounds and less magazine manipulation. I did not think it was that big of a deal, but when we got down to drills that required more than 8 or 9 rounds it made a difference. By the end of the day I was helping him reload his magazines to keep up with the class. I still love my 1911 though, big holes on the target always get noticed.
Bottom line, very good pistol, easy to shoot, fits like a glove and zero issues. I have two other folks in my class wanting an M&P now.
