    I have a gen2 G20 and recently picked up a gen3 G21sf . Does anyone know if the slide and barrel from the G20 will work on the G21sf and vice versa ? What about the mags? Will the 10mm mags work in the G21sf frame?

  3. On sthe same line I'm thinkink of useing my gen3 20 slide on my gen4 21 frame? The mags do interchange in the grip.

    awesome . I thought the G21sf had some issue with older mags?

    That's unlikely to work. The Gen4 frame is sized for the dual RSA.

    Yes, the 21 and 20 share the exact same frame..all parts are interchangeable.

    I think it will actually work, you will just have a gap in the dust cover. I would hand-cycle it extensively to make sure there's no interference. Going the other way (Gen4 slide on Gen3 frame) won't work.
