Alamo15 vs. Other Performance Triggers
Comparison with Traditional Single-Stage Triggers
While excellent single-stage triggers exist, the Alamo 15’s PDR technology provides superior reset reliability and speed that conventional designs cannot match. The positive reset mechanism eliminates the possibility of reset failures that can occur with rapid firing.
Comparison with Two-Stage Triggers
The Alamo15 offers the speed advantage of a single-stage trigger with reset reliability that exceeds many two-stage designs. For applications where rapid, consistent shooting is prioritized over the precision advantages of two-stage triggers, the Alamo 15 excels.
Comparison with Other Enhanced Triggers
Where many enhanced triggers focus solely on pull quality, the Alamo 15 addresses the complete trigger cycle—pull, break, reset, and subsequent engagement. This comprehensive approach to trigger performance sets it apart from single-focus competitors.
Legal Status & Compliance Information
The Graves Alamo 15 trigger is designed and manufactured as a semi-automatic fire control system. The Positive Displacement Reset technology enhances reset reliability but does not alter the fundamental semi-automatic operation—each shot requires a distinct trigger pull.
