    I currently shoot a Gen 5 17 with an optic. I reload 45 acp now but sold my only 1911 pistol. I am thinking about a Glock 20 (never had a 10mm and that seems reason enough to buy one). I have been shooting a friend's 21 and shoot it well.

    Common sense says buy a 21 since I am setup to reload 45 acp now. The 21 recoil is not much more than my 17. But, the little voice in my head says go for the 20 and start reloading 10mm. Not likely I will ever hunt with either pistol.

    Another option is buy either 20 or 21 and then the other caliber barrel, magazine and recoil spring assembly.

    Analysis paralysis has me stumped. Which way would / did you go?
    Thanks

    If you go this route, which I'd recommend, you'll need a G21 to start.
    You can't put a 21 barrel in a 20 slide, but you CAN put a 20 barrel in a 21 slide.
    45 to 10mm conversion barrels are readily available and that's the best option.
    :)

    You will have less upfront cost reloading and shooting the 21 since you're already invested in it.

    If you think you want to try 10mm in the future, it's easy enough to convert the 21 for 10mm.

    ... plus you can convert the G21 into a 45 Super or 460 Rowland if the 10mm seems too paultry...

    I would get the Glock 21. You're already set up to load .45 ACP, so that is the route of least resistance.

    Thanks for the advice. I'll be watching for a Glock 21 locally.

    I always preferred 10mm in a Glock

    I’d have to ask, “for what?”
    If it’s just because you want a 10mm, then go for it, they’re great. I’ve had both the 20 and 29’s in regular form, SF, and Gen 4. I just decided to get out of the 10mm game for my own reasons.
    I’d suggest 21 for about anything though. The 230 gr. HP from a full-size weapon is very stout in both the penetration and expansion areas. It’s also cheaper at the range.
    As stated, if you went .45 and decided you needed more for the woods (or whatever) it’s fairly easy to convert it to 10mm. But don’t overlook the .45 Super.

    Lot's of experiences, opinions and suggestions here. A few more to follow:

    I bought a Colt Delta Elite 10mm when it first came out and some of the seriously hot 10mm Norma ammo. Great gun, wonderful shooter, the ammo was significant. :D Years later I sold it at a profit, since I didn't find it filled a role I couldn't do with a good 1911 .45.

    Later, I got a deal on. G20, with lesser ammo, though not less expensive. Shot well, ran like a clock, but again, for me, the ammo cost vs. the ammo gain was not worth the difference. Did well on selling it too.

    If I lived or spent time in Bear (or maybe Moose) country, I'd have kept a 10mm, but I don't and I didn't.

    I've got two G21's & G30's, all with grip reductions, they serve me well.

    YMMV

    Lol. 10mm is Ballistically inferior to the 460 Rowland. NOT inferior to a 45 super or even a 450 SMC. With that being said underwood ammo 155s get in the 880-910 ft lbs range from a 6” oem Barrel. So do 125 double tap tac x. And at least 2 Cape buffalo have been killed by a 200 grain hard cast 10mm from a 5”.

    I was in the same boat and just went with what I found used first. It just so happens that I bought the 21 (and then another 21) and am still in the market for a 20.

    I just went through that same choice. I reload for both calibers so that wasn't a consideration. For my own reasons I asked my LGS to order me a blue label 20. I just felt if I was buying a Glock for out of the city trips - where I might end up out in the weeds, a 10 would be a better choice. Plus I can always load a .45 equivalent if needed.
    Gun should come in tomorrow or the next day.

    I bought the G20.
    Fantastic pistol.
    Very accurate and easy to shoot for long range sessions.
    Fun to blow up water jugs and various melons with the high speed hollow points.
    It will make you grin.

    Or you could buy just one and a complete slide and barrel in the other caliber.

    G21, the .45 is the more noble calibere to reload!
    Enjoy!

    Had several of each and a 41 too

    Do the 20 as it will better compliment what you have now.

    I bought the 20 first and then bought a complete upper for a 21 later. Both work great. In your case, pick one and go with it.
