CGW 8.5 Pound CZ SP01 / Shadow 2 Reduced Power Hammer Spring by Cajun Gun Works
This a hardcore “competition” music wire 8.5# hammer spring color coded “white”. Must be used with our reduced power firing pin spring, part number RP-FPS. 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 mis-fires are certain. You must balance your springs for reliable ignition. The CGW reduced power firing pin spring is the perfect match for our HS-8500.

I installed it on my CZ SP01. Trigger is smooth and easy, double action went down to 5 !/2 pounds, single action a steady and consistent 4 pounds every single time. Not a single misfire using Remington 115gr FMJ. (100 rounds) but......then switch to PMC 115gr and had 5 misfire out of 50 rounds. So, not suitable (at all) for defense purposes.
