the guys saying M&p's are #### is totally wrong, they are excellent guns, at a great price.
I wanted a .45 for my first gun, came down to glock, Springfield, and the M&P, and the M&p just had a waaaaaaay better feel, and its going on 3K rounds, with no failures of ANY kind, absolutely none. it has not been baby'd either, in a drop leg holster, gets exposed to plenty of dirt/sand when I shoot the rifle/shotty in 3 guns And i have only cleaned it once.
the glock and springfeild both went bang everytime I shot them... but really, I didnt like the look, or feel in my hand.
long story short, all are good guns, accurate, reliable, and about the same price,
buy what feels good to you,
