Two months using the S&W M&P 9mm full size. I don't shoot it as much as I like to. But using it for class room demonstrations, I get to operate the controls a lot. As it is now it is box stock. I find the grip more comfortable, and points better than the Glocks I've shot. I like the take down better than the Glock system. I have found that I shoot it as well as I shoot the Glock 17, or 19. It has been very reliable, the only problem being a mag that wouldn't feed. I blame that on being dropped in the mud numerous time at a match. After cleaning the mag, I have not been able to duplicate the problem. Overall I find it to be a fine gun. I guess the question will it hold up like a Glock? I will continue to shoot it in the stock configuration for a while, During that time I will decide what I want to do.
