Trained in MP school with the 1911A1. I was told the M9 was supposed to fit everyone and eliminate the need for the M10 S&W for women. The M9 is too big for my hand, I have numerous reports from Senior NCO's that students have been either taught to cock the weapon or wast the 1st shot! Because of the over sized grip and double/single action system. Never owned or shot one. Picked up and examined quite a few, always thought I should own and or shoot one, never been able to get over the hump!
