I think Last Lemming is correct (solely based on my experience). The 1911 platform is quite different as compared to an N frame revolver when it comes to felt recoil. I can shoot 41 a lot and enjoy it. The 10mm in a 1911 will pound the hell out of an arthritic thumb. For that matter, so will a 45acp. In comparable revolvers the 10mm will be quite manageable. To me the 44 is a different animal.
