To paraphrase Bob Valdez: "when you lighten mainsprings on

Colt and Ruger Single Actions?" "Before I know better." So many folks seem obsessed with lightning mainsprings and they do give a nice smooth light action but only suited for Fast Draw blanks. John Linebaugh and Hamilton would never let a gun out of their shop with a light mainspring. Just this past week I had to change the mainspring on a brand-new sixgun. In this case it was an 1858 Remington .36 which was giving me misfires and hang fires. Percussion caps need an even heavier blow than primers for reliable ignition. The Remington is set up nicely with a strain screw as Smith & Wesson double action sixguns, however it was in all the way so I tried to shim it by flattening out an empty 22 case. The idea worked fine except when tightening the screw which put a little more bend in the hammer spring it would slip out from under the hammer. The new spring solved everything.
