Does anyone know what the trigger pull weight of the ruger factory mainspring is on a .357 sp101 ? I replaced mine with a 12lb. wolf spring and am not feeling a whole lot of a difference. Thanks!

It is not much higher from what I can remember...I believe it is 14#

The 11# one works great in my gun after I slicked up the action a bit. No FTF or light strikes...ever

You will be fine with a 10lb spring. 9lb is a little iffy.
