Just to help you figure out what you're looking at in catalogs, the single action pull is what you get when you pre-cock the hammer with your thumb. The double action pull is when you pull the trigger all the way through the stroke with out pulling the hammer back with your thumb, so on your gun the 14# should be double action, & the 4# single action. I put a wolf set in a Redhawk I had a long time ago, & it helped quite a bit.
