This has been a great thread. I will take the middle road, I like both Glocks and M&Ps. I base my choice on reliability, size, weight, etc. my absolute favorite 45 is my 4506-1, hands down tack driver, eat any ammuntion, ha been 100% reliable. The only issue is the weight. I have a 5903 and 6904, I just like 3rd Gen Smiths. That said, I am issued a M&P 40 full size on duty. I think it is the best 40 cal I have ever fired, great grip, no issues on reliability, in my hands I fired 100 % on my agencies qualification course. I liked it so much I got the compact 40 M&P. Not has accurate as the full size, but I have had only a few FTF when brand new. My back up is a Glock 26 9mm. It is the best compact 9mm I have ever shot. Dead accurate in my hands, reliable, lightweight, and has a very consistent trigger. I recently picked up a Glock 30 sf for off duty carry. This is not my favorite 45. The grip in the M&P 45 feels better, but the Glock 30 sf is so easy to shoot, dead accurate, 10 round magazine, plenty of holsters, magazines, etc you can buy about anywhere. I have carried a Glock 19 and 26 before but became a believer when I carried one in Iraq, bar none, finish, feeding, sun, dust, heat that gun fired. So bottom line for me, even though I bleed Smith and Wesson, the Glock does have a place in my holster based on size, reliability, accuracy, and utility.
