Just ran across this forum on the net. Has anyone had problems with the P3AT jamming? Kel Tec has worked on my gun twice. Still have problems with the gun jamming and not ejecting the shell. I carry the pistol in my business and love the concealability but it scares me to think of having to use it in a defensive situation. My serial # begins with HB####. Are there any problems with this particular batch? Thanks.
