This is our light trigger spring made of stainless steel. With an uninstalled trigger group it reduces pull to about 8 oz or 4 oz if you use our custom triggers which reduce pull by about 4 oz. With an installed trigger group pull will vary by hammer spring tension and how smooth your hammer and sear function. With most pistol models you should be able to get a pull of 8 oz to 2 lbs depending on what other custom parts or tuning you incorporate. It's typical to get 5-6 oz with models like 2300S and 2300T that have a very light hammer springs. Heavier hammer spring tension increases trigger pull because added force on the striker holds the sear in place tighter. For the best accuracy, striker force should be reduced to the minimum needed to produce the power level you need. Our custom power adjusters are designed for this purpose, they can reduce or increase hammer spring tension.

 This spring will only work with a very smooth and easy-functioning group. If the trigger or sear are stiff, bind or have any significant drag this spring may not be strong enough to engage the sear fully. It needs to remain 1.25" long to function. If you compress the spring too far by hand or during installation it will become too short to function reliably. If this happens simply stretch it back to a full 1.25" and reinstall. The trigger group can't compress it far enough to cause this issue.

 The spring should be positioned as shown in the last photo with the spring-wire end lightly touching the side of the sear. This keeps it in place on the sear where it doesn't touch the trigger frame or cover and works perfectly smooth.
