Well, ignorant me just managed to figure out how to post a picture, here.
Here is the TFF link to the entire thread for my post #12 picture, found above.

I have actual knowledge of three different Kahr pistols that have experienced this exact defect; and I have not really worked in the gun business in over 20 years, now.
I hold the opinion that the only way to help Kahr improve their deplorable customer service and apparent disregard for their own defective products is (in my opinion) to "tell it like it is" about their products and services at places like TFF and other forums.
I will add that I like the design and performance of some of Kahr's products; recognize the fact that errors happen when you actually do anything; and recognize the fact that the failure to correct errors usually ends up being significant mistakes.
