Compatibility warning: Model number alone does not guarantee fit. Before installation, compare this pin with the original for overall length, diameter, tip profile, shoulder locations and extractor/ejector-rod interface. Do not substitute it into pre-model or I-frame revolvers without exact dimensional confirmation.
Installation
Installation requires disassembly of the cylinder and extractor assembly. A qualified gunsmith should verify free movement, extractor return, cylinder closing, lockup, endshake, timing and carry-up before the revolver is fired.
