I have a Glock 19 gen. 3 that I like very much. I recently bought an M&P Shield and I love it. Because of the Shield, I'm getting interested in an M&P9 or 9c. I'd like to hear some serious comparisons between the 9mm Glocks and M&P's. I see the possibility of a manual safety as a positive for the M&P's, but I've heard the triggers may be a negative. What say you?
