All trigger components are stoned/polished at their contact points to provide a smoother pull.  A Wolff reduced power spring set is installed.  The hammer, hammer dog, and trigger are shimmed to center as close as possible.  This reduces side to side play and aids in a more consistent trigger pull.  It also reduces hammer/trigger to frame drag marks commonly seen on revolvers.  This service provides a buttery smooth operating trigger/hammer group and a crisp 8 to 9 pound double action trigger pull.
