Quick Answer
To troubleshoot a malfunctioning aftermarket trigger, start by checking the installation and ensuring the trigger is properly aligned with the sear and hammer. Next, inspect the trigger itself for any signs of wear or damage. If these checks do not resolve the issue, proceed with disassembly and detailed inspection.
Trigger Alignment and Installation Check
Verify that the aftermarket trigger is installed correctly according to the manufacturer’s instructions. Typically, a misaligned or improperly installed trigger can cause malfunctions, including failure to fire or premature firing. Double-check the trigger’s position relative to the sear and hammer to ensure a flush fit. If the trigger is not flush, adjust the installation or consider consulting the manufacturer’s technical support.
Trigger Disassembly and Inspection
Disassemble the trigger according to the manufacturer’s instructions to inspect internal components for wear or damage. For most triggers, disassembly involves removing the screws or pins holding the trigger assembly together. Use a small screwdriver or punch to carefully pry apart the components. Inspect the sear, hammer, and trigger spring for any signs of wear or damage. Replace any damaged or worn components with new ones, or consider re-profiling the sear or hammer if necessary.
Dry Fire Testing and Adjustment
Perform dry fire testing on the trigger to verify its functionality. Hold the firearm with an empty chamber and pull the trigger while keeping the hammer at rest. If the trigger fails to fire or fires prematurely, adjust the trigger’s overtravel or sear engagement as necessary. Typically, a trigger’s overtravel can be adjusted by bending the trigger’s pivot pin or by adjusting a screw or Allen wrench. This process may require trial and error, so it is essential to consult the manufacturer’s instructions and follow proper safety procedures when making adjustments.
