Grip, stance and form.
Capitaine Nemo, what you're describing is a classic case of handgun fit combined with proper grip, stance and form. Since you can shoot a revolver well, you've likely got these three down, but the 1911 probably doesn't fit your hands. I have the opposite problem, I've yet to find a revolver that's truly comfortable for me to shoot. With a 1911, I get minimal muzzle rise after the shot. When I'm "in the zone" and my form is dang near perfect (not often), I get nearly zero, as the recoil is distributed into the hands and arms while the pistol frame stays stationary.
