I found a P11 with a hard chrome P40 slide and barrel today at one of my local pawn shops. The frame and mag were clearly marked P11 9mm, and the slide and barrel were clearly longer than the frame. The barrel was obviously not a 9mm. Could this be an early P11 with a P40 conversion kit? The guy had it marked down from $329 to $299. It was in very good shape, but did not have an original P40 frame. Would this model be a reliable shooter with the P11 mags? (without the modified crescent shape cut out of the P40 mags) Is $299 a good price for this gun? It seems a little steep to me. OBTW he doesn't know what he's selling, he has it for sale as a 9mm.
