Make your Ruger Single Action feel more like a Colt. This Trigger and Hammer Kit offers a 2-1/2 to 3 lb trigger pull for all New Model Large Frame Single Action Blackhawks, Super Blackhawks and Vaqueros. When on halfcock and the loading gate is opened the chambers line up for no fumble reloading. Spin the cylinder and hear the pawl sing, and when you pull the hammer back you can hear and feel 3 positive clicks. A Wolff Spring Kit is included in the kit with three different reduced power hammer springs (17 lb, 18 lb and 19 lb), a reduced power trigger spring and 1 extra power cylinder latch pin spring. Minor modifications are required to some factory parts. Includes detailed instructions. Hammers and triggers available separately.
