I'm curious... I'm considering having a full action job done on a Model 60, including having the hammer bobbed. It's been my understanding for many years that the weight (mass) of the hammer in its original configuration adds to the successful ignition of the primer. Seems to me (intellectualizing here) that having the action job accomplished AND having the hammer bobbed may be counterproductive to successful ignition. Whaddaya think? Anybody have any real experience in this regard?
