Well, I reworked my pistols, and now have 4 blackhawks with ~3.0 lb triggers. As an aside, I did learn that one can replace the triggger return spring and hammer spring, without pulling the grip frame off the revolver. Anyway, I will have to go shoot these and see how they feel.
In response to your comment, Lloyd, some of us like to learn about these mechanisms and how they work. Your statement is well founded, but not applicable to everyone. I have tended to dive in, perhaps too far sometimes, when it comes to working on my guns and my cars. But, that's all part of the fun.
Best regards, Tom
