This started as plain Jane stainless Colt, I added the ball, high power and front cocking serrations for the owner as well as new front and rear sight. 10-8's in the rear and an XS Big Dot up front. The GS is an EB without the speed bump and the TS is a EB wide. I Nitre blued the pins and hammer to set them off from the stainless. The grips are VZ's. The front strap is hi cut and checkered 20lpi for a good firm hold out of the holster.
