This a hardcore “competition”  music wire 8.5# hammer spring color-coded “white”.  Must be used with Cajun Gun Work's Reduced Power Firing Pin Spring.  CGW has built Shadows using this spring with trigger pulls as low as 4lbs 7oz.  NOTE:  For use with Federal primers only, never use this spring in any self-defense firearm.

TECH TIP:  Never change the hammer spring only or misfires are certain.  You must balance your springs for reliable ignition.  The CGW Reduced Power Firing Pin Spring is the perfect match for our 8.5# Hammer Spring.
