First off welcome to the forum..........Sorry to hear about your bad experience with the gun. I have owned 4 different Kahr guns and outside a couple of ftf's during the first 100 rounds on 2 of them, no issues after that. From what you say it unfortunately sounds like you did get a lemon. I would do the same as you have done ask to have the gun replaced. As you said the others that have Kahrs love them, I feel the same about mine. Sometimes a bad one gets out there. I hope they make it right for you......!!!
