1. Trigger Quality
SIG P320
The trigger pull on the SIG P320 is smooth and consistent, with a range of 5.5 to 7.5 pounds. In my tests, the trigger provided a crisp break and a short reset, which is ideal for rapid follow-up shots.

The smoothness and consistency in the P320’s trigger pull make it a more comfortable choice for both repeated and precise shots.
