About 1903, Colt removed the shoulders from the chambers and changed their advertising to say that .38 Special could be fired in those revolvers. They changed the military contract guns at the same time. In fact, the cylinder and frame are the nearly the same as the Colt Army Special, which picked up the New Army and Navy serial numbers. We don't know the serial number of the revolver in question, but if .38 Special will fit, it should be OK to fire it.
Of course, that is the so-called "standard" .38 Special, the factory round-nose lead bullet or equivalent, NOT +P, +P+ or some super hot hand loads.
