I just recently got interested in SA's myself. Here is my only SA. It's a Blackhawk .45 Colt with the following modifications: trigger return spring changed out to produce 2.5 lb pull, Belt Mountain base pin, free-wheeling cylinder, custom front sight, Bowen Rough Country rear sight, Bisley grip frame (including hammer and trigger), Buffalo Horn grips by Eagle, Cylinder throats reamed to .4525, and barrel firelapped. Handles and shoots like a dream. I don't even want to shoot my DA's anymore.
