For what ever this is worth. You are going to get many "opinions" on this. Some say the bobbed hammer gives you the advantage of a faster fall minimizing gun movement at time of discharge of round. Looks cool. Lightened trigger pull in DA.
Others will say it is a disadvantage in that a lighter hammer will give you lighter strikes, therefore inconsistent primer ignition(effecting accuracy),misfires(clickies), and or not that much a real difference on hammer fall. Wind up sometimes tightening down on main spring to get better ignition making DA heavier(some folks like heavy DA though)Also in the stages at 25/50 yards you get a high primer or dirt under the extractor, or round not seated 100% and you cant reach over and use that spur(if you are on top of things) to get that cyl around to next round and stay in the game.
Do some homework, read up on pros and cons about doing this alteration before doing any surgery. Get another hammer if possible and save the original if possible and try it to see if makes a difference for you. Prob more psychological and cosmetic than real advantage if anything.
Just another "opinion".
