A trigger can be adjusted too light to be considered safe depending on the firearm configuration, shooter experience, and intended use. As trigger pull weight is reduced, spring tension within the trigger system is also reduced, which may affect the suitability of the trigger for certain applications.
Factors that can influence what is considered a safe pull weight include:
- The specific firearm configuration
- Shooter experience and familiarity
- Intended use case
- How the firearm is handled and operated
TriggerTech strongly recommends spending time with the trigger at the factory setting before making lighter adjustments. In general, a trigger set at 4.0 lbs provides a greater margin of safety than one set at 2.5 lbs.
Always perform a full safety function test after making any adjustments, and discontinue use immediately if the trigger behavior changes unexpectedly.
