Smith & Wesson J Frame Pre-Model 31 Regulation Police Action Parts Set Trigger Hand Cylinder Stop .32 S&W Long Used - P6

Smith & Wesson J Frame Pre-Model 31 Regulation Police Action Parts Set — Trigger, Hand, Cylinder Stop (Bolt), .32 S&W Long, Used

Part #P6 | Used | J Frame | Pre-Model 31 (.32 Regulation Police) | 5-Screw Era | .32 S&W Long | Action Parts Set

Genuine used Smith & Wesson action parts set for the pre-model 31 .32 Regulation Police J Frame revolver. This lot (Part #P6) includes the following four fire-control components removed from a 5-screw pre-model J Frame:

• Trigger — DA/SA double-action trigger; cams the hand during trigger pull to rotate the cylinder and cock the hammer
• Hand — rotates the cylinder by engaging the cylinder ratchet; critical for cylinder timing and lockup; worn hands are the most common cause of cylinder timing failures in vintage S&W revolvers
• Cylinder Stop (Bolt) — drops into the cylinder stop notches to lock the cylinder in alignment with the barrel during firing; “Cylinder Stop” and “Bolt” are S&W’s interchangeable terms for this same part

Pre-model 31 action parts in this 5-screw era configuration are increasingly scarce. This set is suited for restorers and gunsmiths sourcing multiple fire-control parts for a single pre-model .32 J Frame overhaul.

Used Condition: Genuine used OEM parts. Expect normal wear consistent with vintage revolver action components. Parts have been inspected for obvious damage. Verify fit and function with your gunsmith before installation; worn parts may require fitting or replacement of mating components for correct timing.
