Second hand only about 200 round through and no wear on feed ramp or slide. Came with a 33rd clip (not glock) and the real icing an AA 22 conversion. I am not even going to post the price, guy must have been hard up. I have only shot it a couple times just to make sure it fired, etc. LOVE it. Can't believe I have never tried one before. 1st question: Does it hurt to fire CCI rat shot through it? It cycled 3 rounds fine. 2nd question: Does anyone have an opinion on the 15/17 round clip adapter to make the grip more like a G17/19? 3rd question: the 33rd clip hung up around 12 rounds before empty. there was some extra plastic from the mounding process, I cleaned it up with rolled up sand paper and cleaned/lightly oiled the mag seems okay but I haven't fired it. Anything else that might help? Not a glock mag, looks the same but no markings. Great site, thanks.
