Our Assessment: Thomas Haas was a famous gunsmith from Anderson, Indiana that went out of his way to completely customize high end firearms for his rapidly expanding customer base. He modified this early 1878 made Colt Single Action Army to fire .22 Long Rifle, he honed the action, timed the cylinder to tightly lock up, and he masterfully engraved the gun before applying a new blue finish. Haas served in World War Two and was very good friends with Elvis Presley, who was also a WWII veteran, those who had firearms customized by Haas would never forget his attention to detail and metal mastery. Early Colt SAA revolvers only appreciate down the road, this one should do so exponentially given its link to Mr. Haas, who died in the early 2000’s. This is a rare opportunity to own one of the world’s most famous firearms with a unique chambering and overall build. For a full read on Thomas Haas, visit
