I have this old Ranger .22 model and maker unknown. I lost the firing pin a year ago, appearantly the retaining pin had fallen out. I recently found a firing pin that looks exactly the same but I'm struggling to figure out how the retaining pin fits into the notch. It seems either the cutout on the firing pin isn't deep enough or the retaining pin needs to be precariously set rather shallow. I hope this makes enough sense!! I used a Brad nail to mess around with it, tried flattening the Brad nail to see if it would clear the cutout but it still wont slide all the way down.
