I just bought new P-3AT and decided to clean it before taking it to the range. I found that I couldn't remove the assembly pin. Part of the head of the pin was inside the frame causing it to be jammed. I am new to both the Kel-Tec and the Owner's Group which I explored extensively. Without the knowledge I gained from the site, I doubt that I would have made the purchase. It would appear that I need to send it back to Kel-Tec unless anyone has a better idea.
