While fitting an overtravel stop inside the triggerguard of my GP100 I found that if I adjusted it to where the trigger just let off the hammer from single action position, there is a slight internal rub or catch of the hammer in its travel about 1/3 of the way down in its arc of travel. Anyone found this before? I'd prefer to leave the stop at its setting with minimal overtravel, but I don't want wear on a sear surface against something. Suggestions?
