I used to have a pair of them. A steel frame and alloy frame in Commander size. I mostly shot the steel one to minimize wear on the alloy frame, but I never really noticed any difference in recoil.
When I had those two particular guns I also had a Gold Cup I shot a lot. It had a different feel, but recoil wasn't an issue with it either.
I think proper technique negates a lot of recoil issues. After all, the .45ACP is not a very high-powered gun.
I will add this, I have a 20 oz. .45 with a poly frame that is not a lot of fun to shoot. It's a little bit sharp under recoil, but it isn't near as uncomfortable as my poly-framed Kahr in .40S&W. But, my wife shoots the Kahr almost exclusively. She's only about 5-feet-4, but she prefers it to everything else I own and doesn't mind the recoil one bit.
