The simplest and easyst way to get a reduced trigger is to simply order the Reduced Spring Pack for Ruger Single Action Revolvers from Wolff Spring co. Cost a whopping $13.50 + shipping, and contains a reduced hammer spring, reduced trigger spring, and an extra strength base pin spring. Simple to put in, and dead reliable.
Got them in all my Single Actions, regardless of make. Even my Colts from the Colt Custom shop has them in now.
