Rey, The pin to hold the front sight blade on my S&W model 34 broke and stuck a paper clip in and bent back and forth till it broke in place. Forget how long ago but its still there. Used the heavy cell foam from a recoil pad to stop movement on GP-100 grips. Had similar damage to the Accro rear sight on my Gold Cup but was able to file and blue... Then I can rely on good people like you to come up with a spare firing pin for my Freedom when hunting at the YO.. Since that day I always carry a spare firing pin and pin spring along with a split driver bit should that happen again.
