The serrations aren't that great on the M9 and I guess I got lazy. The safety wasn't engaged so it was flipped up pointing towards the muzzle and I pulled it back hard on the serrations it slipped and this is going to take a month to heal and maybe a clinic visit for some stitches. In it's defense I've got old geezer hands. Gonna start wearing gloves from now on. I have some real nice tactile range gloves. All I was doing was clearing the breach why I flipped the safety off .. I guess because I had just cleared my SA-35 and you have to flip the safety off to pull the slide back. This is one of those things I will never do again.
