Steel frames, of course, means heavier gun which translates to less muzzle rise. Also the 1911 frame is made in such a way as to allow a high grip on the firearm, thus the recoil is directed straight back into the shooters hand. With that said, a polymer gun like the Glock will jump more in your hand just because of the lighter weight, but..the polymer frame absorbs more of the felt recoil so even shooting the venerable .45 is not unpleasant. Get your Glock and get to making it dirty!!!
