I run 22lb springs in my Ruger and all my other 1911's. I use only factory ammo and a lot of time some pretty hot stuff, but even with the WWB, Federal cheapos and Remington UMC they run perfect, extract and eject perfect and I end up with less felt recoil and better controlability because of it. Faster sight acquisition shot after shot. These have been my experiences, others may differ, but I certainly aint changing from the 22lb.
