Colt Single Action Army, serial 356951, made in 1939 and chambered in .357 Magnum with the 7 1/2-inch barrel, a scarce chambering for the model. The gun retains about 70 percent of its original blue, the frame still shows case colors, and the ivory grips are excellent and fit the frame properly. It comes with a Colt factory letter confirming the caliber as shipped.

Condition is described as very fine, and the factory letter is the piece of paper a serious Colt collector wants with an uncommon caliber like this. In Massachusetts it buys and transfers like any other handgun: a License to Carry from your local police chief, shown to the dealer in person, followed by the federal check and the entry in the state gun portal. No separate permit and no state waiting period apply beyond that, and the .357 chambering means it remains a revolver that can be shot rather than only looked at.
