The Brownells Colt SA Hand Slot Stoning Kit is perfect for cleaning up your Single Action Army frame. Deburring and stoning are especially important on third-generation Colts and clones with cast or roughly forged frames. This stone kit also works very well with first- and second-generation Colt frames. The MF-414 stone fits nicely in the hand slot and cuts quickly to get rid of casting roughness. Follow with the HF-823 to make a slick, polished path for the hand. Use the MF-14 to round the nose of the hammer notch. Thanks to Eddie Janis of Peacemaker Specialists for his help with this kit. The MF-14 and MF-414 Stones are available separately.
