Trigger Pull Percentage Explained - MCARBO - Best Trigger Pull Gauge

This video provides an informational explanation of how trigger pull reduction percentages are calculated using a properly calibrated trigger pull gauge. The content focuses on measurement concepts only and does not include instructions on firearm modification, adjustment, or installation. To determine a trigger pull reduction percentage, many shooters compare the difference between a factory trigger pull value and a modified value, using a multi-pull average for accuracy. Understanding these measurements helps users evaluate consistency and performance characteristics when working with trigger systems. For the most accurate results, it is important to use a trigger pull gauge designed specifically for firearms. Precision tools in this category are engineered to provide repeatable, reliable measurements, unlike general-purpose scales that are not calibrated for this application. The video also discusses several commonly used types of trigger pull gauges—both digital and mechanical—and highlights features that can assist with achieving accurate readings. This video is strictly educational. It does not provide guidance on altering trigger systems, making adjustments, or performing any gunsmithing tasks.
