The Brownells RSA-100 17 LB. Pro-Spring Kit is engineered for New Model Ruger Single Action revolvers. This kit features a redesigned trigger spring paired with a reduced power hammer spring to deliver a smoother, more controlled trigger pull, and includes an extra power base pin latch spring. The 17-pound hammer spring offers a significant reduction from the factory specification, making it ideal for shooters seeking improved trigger performance without extensive gunsmithing.
This upgrade provides an excellent foundation for building a beautiful, smooth and reliably functioning gun. The combination of components in this spring kit addresses the primary factory limitations in trigger quality, making it popular among competitors and recreational shooters alike. Installation requires only basic disassembly, allowing you to customize your revolver’s trigger characteristics for competitive shooting or everyday carry.
Compatible with most modern Ruger Single Action models, the RSA-100 delivers measurable improvements in trigger control and hammer function. The included springs are precision-manufactured for consistent performance and reliable fitting to your revolver.
