I have a Colt style revolver with a VERY creepy trigger. I'd like to reduce the creep. Looking at the innards I can see that if I file away the outer part of the notch in on the hammer to say, half what it is now, I would reduce the creep by half. Of course, I then have half the engagement. If I carry this to the point of very little creep I might have an unsafe trigger. I am wondering just what role the angle of the mating surfaces will play. Any thoughts on this?
