Overview

The Colt M1873 Artillery Model is the 5.5-inch-barrel variant of the Colt Single Action Army, created when the U.S. Army shortened and refurbished its 7.5-inch Cavalry Model revolvers around 1895-1903. Chambered in .45 Colt with a six-shot cylinder and single-action lockwork, the Artillery Model was issued during the Spanish-American War and the Philippine Insurrection.

Notes

Officially termed the 'Altered Model' by the War Department; nicknamed 'Artillery Model' because early reworked guns went to light artillery units. The only mechanical difference from the Cavalry Model is the 5.5-inch barrel (versus 7.5-inch). Refurbished guns characteristically have non-matching serial numbers across frame, barrel, and cylinder.

Background

Theodore Roosevelt's Rough Riders carried 5.5-inch Artillery Models into Cuba in 1898; the conversion was driven by complaints that the longer Cavalry revolvers were cumbersome and that the .38-caliber Colt M1892 lacked stopping power.
