    Are the G20 and G21 the same size, for the purpose of fitting a G20 to a G21 holster?

    I believe that they are very close if not identical as far as holster fitting goes.

    A quick check of galco shows that they sell the same holster (CM228) for both the G20 and G21.

    Check it out be selecting the G20 and then a style and getting the holster number. Then do the same for the G21 and compare holster numbers.

    Thanks. That is the exact holster (used) I was looking at. The seller stated it was for a G21 but didn't know fit would fit a G20.

    They are the same size. Although as far as holsters go, there can be some issues, the G20 and G21 fit the same holster, but the G21sf will sometimes not fit in the same holsters since it has an ambi mag release, but as far as I know, none of the G20sf have that release, so they all fit fine.

    Is the G20 the 10mm? If it is, and neither of the guns in question are designated as a slim frame, they should be (exterior) dimensionally the same.
    I recall researching that the G21 uses the 10mm frame, which is the largest (aside from the target/competition guns) frame Glock makes. :thumbup:
