What To Know
- The constant friction between the trigger pin and its hole can gradually wear down the surfaces, reducing friction and allowing the pin to move.
- Staking involves creating a small deformation or dimple around the edge of the trigger pin hole to retain the pin in place.
- Using anti-walk trigger pins, staking the trigger pin, or installing a trigger pin retainer are the most effective methods to prevent trigger pin walking.
Trigger pins play a crucial role in the safe and reliable functioning of firearms. However, over time, these pins can become loose and “walk” out of their designated holes, leading to potential malfunctions and safety concerns. This article provides a comprehensive guide on how to keep trigger pins from walking, ensuring your firearm remains safe and operational.
Understanding Trigger Pin Walking
Trigger pins are typically held in place by a combination of friction and mechanical interference. However, factors such as wear, vibration, and improper installation can cause these pins to loosen and move out of position. This phenomenon is known as trigger pin walking.
Causes of Trigger Pin Walking
- Wear: The constant friction between the trigger pin and its hole can gradually wear down the surfaces, reducing friction and allowing the pin to move.
- Vibration: Firearms generate significant vibration during firing, which can cause the trigger pin to shake loose from its hole.
- Improper Installation: If the trigger pin is not properly seated or staked in place, it can become loose and walk out.
Prevention and Remedies
1. Use Anti-Walk Pins
Anti-walk trigger pins are designed with features such as serrated surfaces or detents that resist movement and prevent walking. These pins are typically made of high-strength materials and are recommended for firearms subjected to heavy use or harsh conditions.
2. Staking the Trigger Pin
Staking involves creating a small deformation or dimple around the edge of the trigger pin hole to retain the pin in place. This method is effective but requires specialized tools and should be performed by a qualified gunsmith.
3. Applying Threadlocker
Applying a small amount of threadlocker to the trigger pin can help prevent it from loosening. However, it is important to use a threadlocker specifically designed for firearm applications and to follow the manufacturer’s instructions carefully.
4. Installing a Trigger Pin Retainer
Trigger pin retainers are small devices that fit around the trigger pin and provide additional support to prevent it from walking. These retainers are available in various designs and materials, such as polymer or metal.
5. Proper Installation
Always ensure the trigger pin is properly seated in its hole before staking or using other retention methods. Push the pin in firmly until it is flush with the surface of the firearm.
6. Regular Inspection
Periodically inspect your trigger pins for signs of wear or movement. If you notice any looseness, address it promptly using the appropriate prevention or remedy method.
7. Professional Service
If you are uncomfortable performing trigger pin maintenance yourself, it is recommended to seek the assistance of a qualified gunsmith. They can inspect your firearm, identify any issues, and provide the appropriate solution to prevent trigger pin walking.
The Bottom Line
By following these comprehensive guidelines, you can effectively keep trigger pins from walking and maintain the safety and reliability of your firearm. Remember to regularly inspect your trigger pins, use anti-walk pins or other retention methods, and address any issues promptly to ensure your firearm remains in optimal condition.
