S&W N Frame Model 28-2 Bolt, Plunger & Spring .357 Magnum – Part# 2845

Smith & Wesson N Frame Model 28-2 Bolt, Plunger & Spring – Old Style

Restore reliable cylinder rotation and lockup on your Model 28-2 Highway Patrolman with this factory-original bolt, plunger, and spring set. The bolt (cylinder stop bolt) works in conjunction with the cylinder stop to index and lock each chamber in line with the barrel at the moment of firing — a worn or damaged bolt leads to cylinder timing issues and inconsistent lockup. This old-style three-piece set is the correct 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.
