You can't get a great action job with out cleaning up every bit of
roughness inside the Single Action Army's frame. You'll be amazed
at how much you can reduce the single action's cocking effort and
lighten perceived trigger pull without ever touching the critical
trigger/hammer notches. Well worth the effort on first and second
generation Colts, especially important on 3rd generation and
clones with cast or roughly forged 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.
