Developed as a combination of the Mark V Trooper frame and the Python barrel, the Colt Boa was manufactured only in 1985 as a Lew Horton Distributing limited edition, with a total run of only 1,200, with only 600 in this configuration, making it among the rarest of the production model Colt "snake" double actions. Blade front and adjustable notch rear sights, with "BOA .357/357 MAGNUM CTG." on the left side of the barrel, and a pair of checkered wraparound hardwood grips with Colt medallions.

Excellent, with 95% plus original blue finish, showing some light spotting concentrated on top of the frame and in a few small spots on the cylinder, along with some light handling marks. The grips are also excellent, with some light dings and sharp checkering. Mechanically very good. A top notch example of a hard to find Colt "snake", worthy of the most advanced revolver collections.
