Sig Sauer P320 Action / Trigger Pull Reduction Tuning Kit
For ALL 320 Series Pistols (incl. M17/18, AXG, X5, Legion X5, XTen etc.)
The desired trigger pull weight can be achieved by installing anywhere from 1 to up to 5 springs. Depending on how many of the tuning springs are installed, the final trigger pull weight will be reduced by anywhere from 0.5 to 2lbs. The final pull weight will vary from one firearm to another and will depend on:
- which of the tuning springs are installed
- how many tuning springs are installed (1 to 5)
- the starting trigger pull weight before this kit is used
- other modifications already done to the pistol
- which type of the trigger is in the pistol
For example: the SIG P320 Legion / Flat Skeleton Trigger as well as the Armory Craft Dual Adjustable triggers have a different geometry than a standard P320 trigger (curved or non-skeletonized flat) and their trigger pull weight is already reduced by 30% compared to those basic P320 triggers. You can purchase Armory Craft P320 Dual Adjustable triggers HERE.
