    Recoil, Safety, Reliability

    There are many similar excellent threads, but I have a unique question. I have NO experience with the 45 Super, my only real expertise is with water guns :ffighter:

    Someone is buying a G21 or G30, but wants to use it often in the lower 48 as a woods side arm. He has a couple of choices that I don't have experience with, so I'm asking which is most reliable, safe and how the recoil may compare.

    1. G21/30- Spring change, recoil buffer. Stock barrel shooting 45 Super.
    2. G21/30- Spring & Magazine change, 10mm Conversion Barrel.
    3. G20/29- Skip the rest and just buy the woods Glock 10mm.
    4. Option4- Tell me what your preference would be.

    3. Even in the lower 48 there are creatures where penetration is essential. 10mm wins that contest. For creatures where as rapid a stop as possible is the goal - cougar for instance - there are 10mm loads that will equal .45 Super. All you have to do is decide what animal is going to attack you at a particular time and load with the approriate magazine.

    There's another option which I don't know much about. G21 plus conversion barrel to shoot .40 super, which produces more energy than 10mm, IIRC.

    45 super can be shot out of a stock g21?

    IE barrel, magazine, extractor?

    Didn't even know there was a .40 Super. Looked it up on Wikipedia and judging by the ballistics, it's looks to be one NASTY round.

    I think so, but I would definitely put in a heavier recoil spring before doing it.

    From what I hear, it's possible to only change the recoil spring. And preferably, adding a recoil buffer to decrease the battering ram effect.

    It supposedly does wear the gun down quicker than standard 45 ACP.

    If he buys a conversion barrel, it will be a 10mm, because that's what I have and we can share ammo. So the only option other than 10mm is 45 super. I just don't know how reliable either is in the 45 ACP.

    I have a longslide and 6" barrels in 40 Super and 45 Super that I would use if I got back into that.

    im considering a 45 acp Glock. Can you just shoot 45 super out of them stock, or would a new spring be advised? Also, how does it compare to 10mm, and are there any safety issues?

    Thanks

    Felt recoil between 10 and 45 Super is pretty much the same. Stronger recoil springs are needed for use with the standard 45 slides.

    Many people pop a 22-24 lb spring in. Safety issues....I have no idea...

    Yeah, but in a self-defense situation, I wonder which would stop a Grizzly or Polar bear faster :shocked: :whistling:

    I do not have any experience with 45 Super but do with the G20SF in 10mm. Heck of a handgun and made better by reloading for it.
    I like my full size G22 and G20SF.

    If you are serious about a Glock woods gun, 10mm is your best option.


    Can't even find those calibers on the shelf at some gunshops.

    What good is a gun if you can't find ammo for it unless you reload?

    45 super and 40 super and these other wildcat calibers only work for reloaders and there is little trade-in value on the wildcat barrels and conversions.

    I prefer my G20 on mu hip when near bear country while turkey hunting. The data shows that 10mm will deliver 694 fpe just as good as 45 super.

    Not a guide gun but it's a start.

    Shooting hot 40SW, 357 sig, and 10mm with both spring weights - no problem. Just locks lockup a tad. So only count on one maybe two shots in close quarters. YMMV.

    You should only do 45Super in a G21 with Comp. If you do this, you can load the 45Super to be more powerful than 10mm.

    If you don't like having a comp.
    or
    If you don't like reloading.
    or
    If you want a smaller gun.
    or....
    Get a 10mm
