I own a .38 special and the problem with owning this as I have noticed is the firing pin will slip from time to time. Well one night my firing pin slept for good and I have a gun that basically has no purpose at all. Were Can I purchase a new firing pin for a .38 special. (If you don't know what im talking about the firing pin is the long pin like thing that twist in underneath the fire hole. Plz help thanks.
