I pressed the slide stop down, and the gun fired the rest of the magazine fired ok. The second time I went to the range I fired 100 rounds on MY MK40 and had two failures. I fired 100 rounds from my Glock 21, with no problems. I am using American Eagle factory ammo, so I doubt it is the Ammo. It was suggest that my thumb was hitting the slide stop so the next time I was at the range a fired another 100 rounds with two failures. I was very careful with my grip and am sure it was not my grip causing the problem.
It has been suggested that it might be the slide stop spring but I have visually inspected it and it looks ok. I called Kahr service and was very disappointed with who I talked to. They offered no help and suggested it was my problem. I need this gun to work 100% of the time, because I bought it for Self Defense, but cannot use it for that if I am not 100% confident in its performance.
I am very happy with the gun, even at the third time at the range, it is reasonably accurate. I was able to get 96% of my shots in the inner two circles. I need to get more exprience with it, becasue I am use to Glocks, as I can usually get 98% if my shots in the inner circle on an NRA D-1 target with my Glock. But I need it to work 100% of the time.
I would appreciate know if you figure out what is causing your problem, or you get a better response from Kahr than I did.
You didnt happen to talk to Ian did you. I recently had the displeasure of dealing with him about the crappy wood grips they sent me and along withbeing unwilling to help in any way, he was also very rude.
I hope i never have any more problems cause from what i have seen kahrs customer service succcckkkkkkssss
GLOCK... THE POOR MANS KAHR.
