Good morning, my question for the day is can you buy a Glock 20 barrel and magazine and swap out on the Glock 21?

    No. The G20 & G21 frames are the same. You can put a G20 upper half(slide, barrel, guide rod, etc.) on a G21 frame and it will work fine, or vice versa. The mags will work in either.

    A few weks ago at the range we yanked the uppers off my 21 and my friends 20. Frame and slide dimensions looked the same but the 20's frame looked and is beefier on the inside than the 21's frame. If at all, I'd run the 21 upper on the 20 lower but not the opposite. I'd also contact Glock first or get the gun for the caliber.
