The firing pin is the component that strikes the primer to initiate ignition — on the 642-2, it is frame-mounted and driven by the transfer bar system, which only allows the firing pin to contact the primer when the trigger is fully depressed, providing a critical passive safety. A worn, chipped, or broken firing pin causes light strikes, misfires, or complete failure to fire. This stainless steel firing pin is the correct factory replacement for the J Frame Model 642-2 chambered in .38 S\u0026amp;W Special +P.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 642F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Smith \u0026amp; Wesson J Frame Model 642-2 Airweight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e .38 S\u0026amp;W Special +P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Firing Pin (Frame-Mounted)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Used (factory original)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Professional gunsmith fitting required – firing pin fit and transfer bar engagement are critical safety functions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFactory Replacement Quality\u003c\/h3\u003e\n\u003cp\u003eGenuine Smith \u0026amp; Wesson factory part manufactured to the exact specifications and tolerances of the original — same dimensions, same tip geometry, same reliable primer ignition.
