The Pioneer Gun Works Coil Mainspring Assembly Kit

The only performance part that we have patented with the US Patent office! The PGW coil mainspring kit displays the most unique and innovative design available while offering the lightest and smoothest feel to your overall hammer spring tension. Fully replacing the curved leaf spring, the kit comes with a roller bearing strut-arm that rides along the inside radius of the hammer rear. Collapsing one of two set tension coil springs, once the the trigger is engaged the tension is released and the hammer it PUSHED forward! This entire action and design adds a smooth tension increase, while aiding in minimal energy loss which gives a more positive rate of primer ignition.

*You do NOT need to be a gunsmith to install this kit.

*Two springs (one red, one blue) come with the kit. The red spring is the lightest spring and the one best to be installed for the lightest tension regardless of the caliber! The blue spring is 10% heavier, for those that wish to increase lock-time or for personal preference.

*Spacer washers are also added with the kit that allow you to manually add tension to the springs, and re-establish spring tension if you decide to clip off a coil and felt it to be too light.
