Tough sell...I'm a G21 guy myself, but I was thinking about making the leap to an M&P45. Just can't quite get there. My Glock shoots really well (I shoot it as good as I can a Kimber 1911), so I'm hesitant to retire the ol' girl. Shot an M&P 40 one time, but I've never liked the 40 cal platform on any pistol.
