I have a nice PT-100AF/S. I have never wanted a 9mm, but I recently came across a "parts kit" with a complete stainless slide and barrel for a PT-92. Thinking it might be worth the time to see if this will fit my PT-100 frame and let me shoot some 9 without having to buy another pistol in a caliber I don't really want. Anybody know if the barrel/slide is directly interchangeable? I stuck a couple of 9mm rounds I found on the ground at the range, into one of my mags, and they seem to fit ok..Just looking at this as an experiment, since it shoots perfectly with the .40's...
