Quick Answer
Regularly clean and lubricate the trigger mechanism, inspect for worn or damaged components, and consider replacing springs or other parts as needed to ensure optimal performance.
Inspection and Cleaning
When maintaining an aftermarket trigger, inspect the entire mechanism, including the pivot pin, sear, and disconnector. Use a soft-bristled brush to gently remove dirt, grime, or debris. Submerge the trigger in a cleaning solution, such as Hoppes No. 9, and let it soak for 15-30 minutes before rinsing with a soft cloth. Dry the trigger with compressed air to prevent moisture buildup.
Adjustment and Tuning
Most aftermarket triggers come with adjustable components, such as the sear engagement and overtravel stop. Adjust these settings to optimize trigger pull weight, reset, and overall feel. Consult the manufacturer’s instructions for specific adjustment procedures. For example, the Timney Trigger System allows for adjustments to the sear engagement and overtravel stop using a small screwdriver. Experiment with different settings to find the optimal combination for your shooting style.
Maintenance and Storage
Store your aftermarket trigger in a dry, cool place away from direct sunlight. Consider applying a thin layer of silicone-based lubricant to the pivot pin and other moving parts to prevent rust and corrosion. Regularly inspect the trigger for signs of wear or damage, and replace any worn or damaged components as needed. For example, the Wilson Combat Trigger features a replaceable trigger spring, which should be replaced every 5,000 to 10,000 rounds fired.
