I guess my question would be, what is the purpose of going to a bobbed hammer that weighs less? I get them for concealment I suppose, but on a full size revolver I don't understand an advantage. Lock time?...

The advantage of the lighter, bobbed hammer is that it moves faster and more powerfully fires the round do to inertia.. You can tune the gun with a lower double action pull using the skeletoned hammer. I've been able to go as low as 4 pounds in my Smith & Wessons. I only use those guns in competition and would never rely on one for carry. My choice.

I haven't given this much thought. I guess it makes sense, given that energy is a squared term of the velocity, so it's worth more than mass. Interesting...
