It just so happens that I went to the range yesterday with my Ruger 1911 and my S&W 1917. Using 230 grain ball ammo. I would say that the recoil sensation was different but not really greater on either on. Now I do use Pachmyer grippers on the 1917 which distribute the recoil over a much larger area that the standard Smith magna grips. Getting a a good fitting grip for YOUR hand makes a huge difference.
