  • Information

The Apex Sigma Spring Kit is designed as a drop in spring kit for the S&W Sigma Series pistol. This kit was developed to reduce trigger pull weight while maintaining reliability. By installing our reduced weight striker block spring, the Sigma trigger pull is smoother and the reset becomes more pronounced. The reduced weight trigger return and striker springs allows for less uptake pressure in order to provide an easier trigger pull every time.

Expected results: 

  • Smooth trigger pull
  • Improved reset
  • Reduced trigger pull weight (approx 5.5 lbs.) 

For use in the S&W Sigma line of pistols (i.e. SW9VE & SW40VE)

NOT for use in the SD Series pistols.  If your gun is a SD9VE or SD40VE, this kit will not work in your gun.  

This kit DOES NOT include a sear spring.  Apex designed this kit to work with the factory sear spring, so removal and/or replacement of the sear spring is not necessary.
