Sig Guy P320 TACTILE TRIGGER RETURN SPRING
 
Click on the last picture in the gallery above to see the trigger scan data for both the factory spring and our spring. As you can see the trigger pull weight, initial take-up and overtravel readings are almost identical. What you  can physically notice is the increase in tactile as well as audible reset performance. Get rid of that squishy factory trigger feel. -SG
 
By using a heavier trigger return spring the squishy trigger feel can be reduced/eliminated
+10% increased strength vs. SIG factory trigger return spring
Although the trigger weight is increased slightly the overall feeling outweights the almost unmeasurable increased trigger weight. 
Improved tactile as well as the audible reset 
 
Manufactured out of chrome silicon alloy by a top spring manufacturer.
