Biggest problem with the M9 other than it being a drinking brick to hold is it was issued with absolute garbage magazines. They were complete junk and responsible for most the problems. Also army wanted you to carry the M9 with the safety engaged. If you were on a FOB it was no round in chamber safety on. The placement of the safety and decocker on it was super unnatural. When we deployed so many new shooters on the pistol had serious issues with the M9. Lots racked the slide and accidentally engaged the safety.
