Analysis

SIG offered the STX as a Custom Shop-oriented full-size model within the Revolution series, emphasizing a distinctive reverse two-tone finish and upgraded wood grips. The flat-top slide, polished serrations, adjustable night sights, and integrated magwell gave it a more refined presentation than the standard Nitron or stainless catalog guns of the period. Hand-fitted components and match-grade internals aligned it with the higher-end offerings of the early SIG 1911 line.
