Analysis

The 45P CS was the Officer-size pistol in RIA's first 1911-A1 wave, sold with walnut grips and a choice of blued, stainless, or two-tone metal. GI Standard CS and TAC Ultra CS later occupied the same compact class with different sights and controls. It is a short single-stack carry 1911 from the early Armscor import mix, not the current compact TAC gun.
