What is a Locking Bolt Pin?

The locking bolt pin is a small but critical component that secures the locking bolt in its proper position within the frame. The locking bolt itself engages notches in the cylinder to lock it in perfect alignment with the barrel when the action is closed. The pin must be properly installed and in good condition to ensure the locking bolt functions correctly. A worn, damaged, or missing locking bolt pin can cause cylinder timing issues, poor lockup, or even dangerous cylinder misalignment.

Signs You Need a New Locking Bolt Pin:

• Locking bolt feels loose or has excessive play
• Cylinder doesn't lock up tightly when closed
• Cylinder timing issues or misalignment
• Visible wear, corrosion, or damage to the pin
• Locking bolt has fallen out or become dislodged

Why Choose Genuine OEM Parts?

When it comes to critical components like locking bolt pins, genuine Smith & Wesson OEM parts ensure proper dimensions, material specifications, and heat treatment. The locking bolt pin must be precisely sized to secure the locking bolt without causing binding or excessive play. Smith & Wesson pins are precision-manufactured to deliver consistent, reliable performance and ensure safe cylinder lockup.
