Thanks, Smithsrevenge,
I had my 36 quite a few years, it was one of the first ones to come out. Liked it a lot, although the recoil with +P was pretty grim, and the gap between the frame and the magazine floorplate would pinch your finger. Sorta sorry I sold it; it was a nice pocket pistol.
I haven't found the need for feed ramp polishing. I'm one of those people who they say are living dangerously; I usually shoot nothing but cast bullets in my Glocks. Haven't had any problems in 9mm and 45, the only two calibers I've owned, and I've shot a lot of cast in them. My 36 shot just fine with the SAECO bullet #451, a 175 gr SWC. Never had any leading problems; I cast my bullets medium soft, and this provides obturation that prevents gas blow-by and consequent leading. That's my experience: I'd appreciate the FIRST HAND experience of others, not stuff generated by the Glock rumor mill.
