Function & Importance
The locking bolt pin secures the barrel locking bolt mechanism that locks the barrel assembly to the frame, ensuring proper alignment and preventing the barrel from loosening during firing. On full lug barrel models, this pin is critical for maintaining the structural integrity of the barrel-frame connection. A missing or damaged pin will prevent proper barrel installation and lockup, making the revolver unsafe to fire.
Important Notes
- This listing is for the locking bolt pin only. The locking bolt, barrel, and associated parts are sold separately.
- This pin is specific to full lug barrel configurations. Full lug barrels have a solid underlug extending the full length of the barrel. It is not compatible with half-lug or tapered barrel models.
- The blue finish is designed to match blued revolvers. For stainless revolvers, verify finish compatibility before ordering.
- This is a factory new OEM part, never installed or used. Manufactured to exact Smith & Wesson specifications.
- Installation may require disassembly of the barrel assembly. Gunsmith installation recommended for proper fit and function.
