Trigger Pull
Home > Examination of Firearms > Examination > Trigger Pull
There are three commonly used methods to determine trigger pull:
- Trigger weights
- Spring scale
- Digital scale
Laboratory protocols may determine the method that should be used to measure trigger pull.
| Note: |
| When testing the trigger pull of a revolver, each chamber of the cylinder should be measured, noting any variations. |
