I've got the 2.0 in the full-size 9mm flavor and liked it so well I went with the 2.0 in a .45 compact. Both shoot great, both fit my hand just right and neither has had as much as a hiccup with FMJ or self-defense ammo.

Typically I add Dawson Fiber Optic front sights and leave the rear stock.

I had a souped-up, tricked-out Model 19 Glock for about one box of ammo and it got traded (for a S&W Model 29-2 of all things -- a guy really wanted that model 19!). I didn't like that gun at all, not the trigger, the grip or anything about it.

You won't go wrong with an M&P....I've got 3 Shields (.380EZ, 9 and .45) and the two aforementioned 2.0s. I also have an M&P that shoots .38 special, but it has a cylinder and only hold six shots.
