Hi so after alot of light hits on every shell I shoot, I have deducted it's time to replace the firing pin. I have all the parts for replacement but don't know how to. Should I take it to a smithy or could someone direct me on how to myself. I do alot of basic gunsmithing for my friends any myself also. I have replaced most parts on remingtons. And even though I shoot a Beretta, I have never had to replace parts in it. If I could get some help, it'd be much appreciated.
