Ok got a nice new little 9mm hole in the man cave wood floor. Earlier tonight was loading my Rock Island 9mm. Slide was locked back, inserted mag, made sure trigger finger was not on trigger or inside trigger guard, pointed gun at floor away from body, dropped slide with slide release. BOOM. Scared the crap out of me, wife, daughters and dog, it didn't seem to bother the cat he came running in and started sniffing and licking new hole in floor. Slide didn't not even cycle after firing, I hand ejected spent casing. Ok what do I need to be checking?
