I have a kahr cm9, went to the range this weekend shooting www. Everything went fine till I got to about 150 rounds. At that point the trigger started feeling gritty which didn't surprise me because it was gettin pretty dirty by that time. What did surprise me is when I pulled the trigger a couple times and it decided to shoot twice with one pull. I'm sure there's a name for that but I don't know what it is. Anyway, is this something to be concerned about? Is there any chance this happening when its good and clean? My main worry is that this is my carry gun and until this last trip to the range had probably close to 750 rounds through it with no problems. I usually only shoot 100 rounds per gun when I go but decided to take 200 with me this time. The first shot hit where it was supposed to but the second threw me off and didn't even hit paper. I always keep my guns clean and don't think it would do it if it wasn't dirty but not sure. Id hate for the time to come I have to defend myself and this happens, the second shot is off target and hits something or someone it wasn't meant to. I've never heard of anyone having this happen with the cm9 so I thought id see what you guys think.
