I got a new Kahr CW-45 about a month ago. I shot it a few times and it would fire about every 10th to 12th round. I used 4 different kids of ammo. rem 185 fjm, some hand reloads, Fed hydroshock, some hornady jhp, and a few others. They all did the same thing. sometimes it wouldnt go all they way into full battery and sometimes it would but it would fail to fire, it wold dent the primer but would not fire, and the slide was hell to pull back as if the throte of the barrel was to tight for the bullet. SO I sent it back to kahr and they replace the whole upper slide and bbl. its still doing the same thing. I called amd they said it needs to be broke in with about 200 rounds of what ever I want to shoot through it. anyone else have this problem with the kahr-CW45? I have a friend that has a CW9 and did not ahve this prob. also someone who had a pm9 with no prob.
