Grendel P-10 hammer spring conversion kit #684-24 (instructions included)
This is a kit we developed to eliminate the troublesome clock-spring style hammer spring, and replace it with a standard torsion spring. No permanent changes to the pistol are necessary. We have sold quite a few of these kits.
This part is manufactured of high quality spring steel and heat-treated to precise specifications in our Midwest facility, using an original factory part for duplication. Some parts may need additional fitting to accommodate wear in old firearms.
Sorry, we are unable to do any international sales of firearms parts due to excessive cost and regulations.
