help I cannot trust this gun to fire everytime. Very ammo senstive and have not been able to associate a particular ammo that will be 100% reliable. It is very unreliable with reloads. Over the past three years the gun has been back to Kahr three times and on the last trip they replaced the entire gun.

I put the gun away for year and discontinued its use, but have brought it back out since it is outstandingly accurate and excellent carry. But can't trust it.
I found a burr on the striker at the point where the safety block plunger had been hitting it. I thought for sure this was the problem but removing the burr didn't eliminate. The striker parts are all free and not binding so- - I'm thinking the trigger bar might have something to do with it.

I read some questions about the trigger transfer bar clearance, not letting the striker spring to pre **** properly any body got some hints.
