I have been working on a load that used 158 grain bullets regulated to my sights and think I am pretty close. Both guns were close to the point of aim with both guns shooting slightly to the right. It thinking the pull to the right might be me. Here are some groups from 10 yards: I shot just a bit better with the 3" but have been shooting that one longer. I then moved out to about 20 yards and shot a group double action. with the 4" I aimed where the red dot is located. Overall I am pretty happy where I am at. I am going to replace the front sights on both guns with Brass Beads. I have a hard time with the fiber optic front sight, although it is much more visible than the black ramp. I do like the finger groveless Hogue grips. They shift the gun up in my hand but fit great. All in all it was a fun morning in the desert. I got some work done and still had time to play.
