S&W N Frame Model 28-2 Trigger Stop Pin .357 Magnum – Part# 28193A

Smith & Wesson N Frame Model 28-2 Trigger Stop Pin – Old Style

Replace a worn or missing trigger stop pin on your Model 28-2 Highway Patrolman with this factory-original component. The trigger stop pin limits the rearward travel of the trigger in single-action mode, preventing over-travel past the sear release point — a missing or worn pin results in excessive trigger travel and inconsistent single-action break. This old-style used OEM part is a direct factory replacement for the N Frame Model 28-2 chambered in .357 Magnum.

Finding Your Model Number

Swing out the cylinder and check behind the yoke on the frame. Model numbers have been stamped there since 1957–58. If your revolver has no model number, it predates that era — contact us with the serial number and we'll help identify the correct part.
