When it comes to merchandise, first impressions are everything. My first Kahr product (MK40) has worked great from day one. I love my MK40 and would have no problem buying another Kahr. But, if I had the same problems as the OP when I bought my MK40, I would likely never buy another Kahr and would never recommend anyone else buy one. I think most people are of the same opinion.
I think I understand where the OP is coming from. I am not very knowledgeable about the issue so I am of no use to him. However, if I could, I would provide as much support to him as I could to get his gun working. Having a successful product that proves reliable over time might remove enough of the bad taste that he might give Kahr another chance in the future. Talking down to the OP and treating him like a child, no matter what your personal opinion is of his initial post, serves no good purpose whatsoever and is actually detrimental.
Rant over.
