I have a Keltec P-40. It is an original .40 S&W, not a converted one. Kel-Tec owners say the P-40 is pretty rare because they don't make them anymore. It shoots fine. I've had it a while but haven't shot it much at all. Maybe a box through it or two, not positive.
It comes as shown with a 9 round magazine.
I would prefer local (Houston) sale but would consider shipping for costs. A pistol/revolver trade would also be considered.
