Gen 4 mod 21 convert to 10mm

  1. I have a gen 4 model 21. Where can I find a gen 4 slide assembly for the 10mm?

    You're going to have a hard time finding one. KKM does make a 45-10mm conversion barrel, but I've not tried it. IF you want more power, think of shooting the .45 Super, it's better than the 10mm and you don't have to buy another slide to shoot it.

    When I wanted to build a G20/21 longslide, I first bought a G20 and sold the slide to someone on here.
    If you want to have both G20 and G21 slides, the easiest route is buying a G20 and selling the frame to someone. There is one guy on here selling G20/21 frames for $225, so that is the price point you would have to beat to sell it online.
