.45 ACP ball has very mild recoil in a Glock 21. My 102lb. Daughter shoot's mine all the time. You wouldn't know first hand about the actual recoil of any of these pistols, would you?andy said:loads. Plus P .45's in 24 oz compact 1911's recoil MUCH worse than 356 Split NOse, but the bozo wouldn't know anything about that, either. Plus P 158 gr .38s recoil so much worse, in an alloy framed snubby, that there's no comparison.
