Think back to your physics classes. It takes energy to move something. Therefore, the more a barrel moves, the more energy it uses, and therefore there is less energy to be transferred to your hand. That is why fixed-barrel pistols have more felt recoil than does a linked barrel (or rotating barrel).

Thanks Phil. Appreciate it. So simple and very well explained. By the way--- never took physics, so congratulations on giving me my first class.
