My favorite Glock 19 is the M&P9.
Your Glock 19 sucks.
hilarious.Interestingly...I have a friend who has an M&P9c and she let me and my wife shoot it!
Sooooooo glad we had the opportunity to do so before my wife purchased her next pistol...she went with the Springfield XDm 3.8 Compact 9mm...which is much nicer than the M&P when it came to accuracy and just plain 'ole shooting fun!
I'll take either, but I like the G4 for the larger mag release and the grip size without any back straps. Those aren't deal breakers, though. I'd be perfectly happy with the G3.
