Anyone familiar with this revolver? I bought mine new last year and like it fine. The only thing questionable is the firing pin. It has that a pressed metal piece that is riveted into the hammer. Some in other blogs have had problems with this breaking. I'm wondering when it will happen to mine. What I was wondering is if there is a standard hammer with a pointed firing pin built in that will interchange with this one so that it would remove the worry from it for me. Funny wording, I know, but to have this accurate little gun for self defense with the worry that the firing pin will break is not a positive feeling. Thanks for any input you have.
