Got to say i had the XD 40, didnt like the feel, and the trigger. After i sold it i wanted to try the Glock 9's and didn't like the feel of them. Tried the M&P's, loved the way it felt in my hand and bought a Pro 9 5" series. Took it out and shot it and completely fell in love w/ it. I have to say i experenced after shooting it i had felt a little grittyness in the trigger. This was after my shooting at the range and cleaning it. Well let me tell you something about S&W. Lifetime warranty. Called them and they sent me a return label for FED EX and sent the gun back and recieved it back with a beautiful trigger that i almost thought they put in a Apex trigger job. Of course they did'nt but these people had my gun back in a week or so.S&W stands by what they make and they dont himm and haw about returns. Since then i picked up a new SD 9 and love that one also. Buy the the M&P. Example, My son whos a cop and armor for 14 years always carried a Glock 27 off duty, tried a S&W Shield and swears by the Shield way over the Glock all day.Sold the Glock and carries the Shield.
