THIS LISTING IS FOR ONE LIGHT TRIGGER SPRING AS SHOWN IN THE SECOND PHOTO, OTHER PARTS ARE SHOWN FOR REFERENCE ONLY

 It should be positioned as shown in the last photo with the end of the spring-wire lightly touching the side of the sear. If installed that way it stays in place on the sear, doesn't touch the trigger frame or cover and works very smooth.

This trigger spring is made of stainless steel. On an un-installed trigger group it has about 8 oz of pull, if used with one of our custom pistol triggers it only has about 4 ounces of pull. That's how much pull it generates on it's own, not including the extra pull caused by the amount of hammer-spring tension you are using once the trigger group is installed. The total trigger pull your specific airgun will have can vary from 5 ounces with light hammer-spring tension and one of our custom triggers to a few pounds with heavy hammer-spring tension and a factory trigger. This is the lightest trigger spring available that will work reliably, it requires a smooth, easy-functioning trigger group, if there's any binding of the trigger or sear it may not work well.
