I have one all-steel, 1911 with a 3.5 inch barrel in .45 acp. The recoil is not bad, though the muzzle flips appreciably more than the longer barreled versions. It would still have less recoil and muzzle flip than than the SP 101 with .357 magnum loads. Recoil on a .45 1911 is more of a push than a snap.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
