I recently came into a late 70s vintage Colt agent. The parkerized one. It has a bobbed hammer. I took it out the other day a d got a whole lot of light strikes in double action mode. Single action was better, but still had a couple. So, I could try bending the hammer spring, or I could buy a replacement from numrich, or if i could find some, i could try federal primers I guess. Anybody have any other ideas on how to make this thing run more reliably? Double action pull does not ear the hammer back as far as single action does.
