i'd get rid of it. no point having a gun that doesn't fire reliably 100% of the time. especially a small, self defense type gun.
what kind of failures are you having? i assume you've tried a bunch of different kinds of ammo and none of them are reliable in this particular gun?
is kahr willing to buy the gun back or give you a new one? that would be my preference, vs. selling a poorly working gun to someone else. i would feel the need to disclose the issues to any potential buyer, which means the sale price would be very minimal.
Yeah, I wouldn't sell a problem to someone without giving a heads-up.
During break-in I had issues with virtually all types of ammo, and it didn't initially seem better or worse with anything particular. However, at this point the only problem I seem to have is occasional stovepipes. I suppose it could be me limp-wristing the gun, but it doesn't seem to be the case.
Now that it is past break-in, one type of ammo has definitely proven worse than others; Remington Ultimate Defense. It seems to stovepipe once every 5-10 shots or so. I haven't shot any Hornady HP stuff since the replacement stop pin, so I should probably try another box of that next time. The last time at the range the very first shot stovepiped, and it was the last round I had of the Remmington stuff. I then shot a mag of Barnes TAC-XPD, then most of a box of FMJ, and it didn't stovepipe again after that first shot. So it has gotten much better. I just don't have a complete confidence in it yet. At this point, if it went a couple hundred rounds of FMJ and a couple boxes of HP (other than the known problem round) without stoppage or breakage, I would feel more comfortable.
The ammo that has so far never malfunctioned once is Barnes TAC-XPD. Ironically, I've read online that this round troublesome in Kahr .380s because of the low bullet weight. It is expensive, and I've only fired about a box and a half of the stuff.
