Quick Answer
A worn-out trigger mechanism can be identified by excessive trigger pull, misfires, and inconsistent shot placement. It may also exhibit a spongy or mushy trigger feel and increased trigger travel. In extreme cases, the trigger may fail to reset properly.
Trigger Pull Measurement
To check for a worn-out trigger mechanism, measure the trigger pull weight using a trigger pull gauge. A new trigger typically has a pull weight between 2.5 and 3.5 pounds. If the trigger pull weight exceeds 4.5 pounds, it’s likely worn out and needs replacement or adjustment. For example, a Remington 700 trigger pull gauge reading of 4.8 pounds or higher indicates a worn-out trigger.
Visual Inspection and Maintenance
Perform a visual inspection of the trigger mechanism by disassembling it. Check for signs of wear, such as scratches, rust, or excessive lubricant buildup. Clean the trigger mechanism and apply a small amount of trigger lubricant, following the manufacturer’s recommendations. For example, apply 0.05 milliliters of lubricant to the sear and hammer pins on a Remington 700 trigger.
Adjustment and Upgrades
If the trigger mechanism is worn out, consider upgrading to a new, aftermarket trigger or adjusting the existing one. Some popular trigger upgrade options include the Timney Trigger, the Jewell Trigger, and the Manners T3X Stock with a built-in trigger system. For adjustments, use a trigger adjustment tool to adjust the sear engagement and trigger overtravel. For example, adjust the sear engagement to 0.030 inches on a Remington 700 trigger for optimal performance.
