My father-in-law recently purchased a used Colt 1991A1 Compact. The pistol fires fine, but when the grip safety is not depressed the trigger can still be pulled allowing the hammer to strike the firing pin (not actually chambering a live round). Essentially the grip safety is not doing its job at all. Oh, by the way, this pistol has a series 80 firing pin block system. So, what do you folks think the problem could be? Any suggestions would be greatly appreciated!
