    Are the Frames on the Glock 20 and Glock 21 the same?

    Yes, the 10mm G20 was built first, then the .45ACP G21.
    Which is why the G21 fares so well in torture testing. The frame was built to withstand the abuse of the more powerful 10mm cartridge.

    So will the G21SF withstand the same abuse of running the 10mm? Can you even run the G20 mags in the G21SF?

    If your pistol has ambi release (not all SFs are ambi), it requires mags with the ambi cut; otherwise, no issues, but the ejector is shaped differently.
