    I'm looking for a handgun that would be most expedient in making the BG (home invader) STOP whatever he is doing.

    I'm looking at these two guns because of the power of the cartridge and the mag capacity, and cheapness of mags.

    But I have never shot a Glock 20.

    How is the recoil of the G20/10mm compared to that of .45ACP? A lot worse?

    I have both and can barely tell the difference. The main difference that I see as far as handling goes is the muzzle flash. A lot more fire out of my G20 and a bit louder too.
    I am biased towards the 10mm because I like it's power but if the guns sole purpose is going to be home defense I'd go with the .45.

    1. The 45 is cheaper to shoot if you don't reload therefore you can practice a lot more if cost is a concern.

    2. Less muzzle flash so if you have to shoot in the dark maybe you'll be able to see after the first shot.

    In the 20 you get 15+1 capacity vs. the 21 with 13+1, The 2 extra rounds in the G20 are no advantage imho.

    My BG in-my-home-stopper is a Mossy 590. Recoil is a bit more than a G20/G21 however :evil:

    I would go with the 10mm myself.

    I have a 20 that I traded in a 21 to get.
    Recoil is very similar, with average 10mm loads recoiling less than the average .45acp. Hotter 10mm loads may recoil slightly more. The 20 has a much heavier slide which really helps.
    If stopping the BG in his tracks is the objective, it's hard to top the G-20 with a Corbon, Hornady or Winchester loads.
    I have not tried anything from Doubletap.com yet, but it looks good. High speed Gold Dots are probably the ultimate.

    I agree with PO2hammer.

    Had a Glock 20, now I have a Glock 21! For home defense .45, but for hunting 10 mm would win out.

    To me the recoil of a .45 is more of a push whereas the 10mm is more muzzle flip and snappier with the proper loads
