The SIG SAUER 1911 STX FULL-SIZE is built on the century-old 1911 platform with modern upgrades: an all-stainless steel frame, Nitron-finished slide, polished cocking serrations and a flat top slide. It ships with burled maple grips and adjustable combat night sights, and includes a magwell for fast reloads.

Design and Tactical Features

The STX is hand-fitted from stainless components and finished with Nitron on the slide to resist wear. Practical details include a beavertail grip safety with speed bump, extended ambidextrous thumb safety, firing pin safety and hammer intercept notch for secure carry. The frame and slide are de-horned for comfortable handling, and the frame sports aggressive 25-line per inch front strap checkering while the mainspring housing has 20-line per inch checkering for a consistent grip under stress.

Performance Components

Internals are premium: match-grade barrel, hammer/sear set, and a crisp single-action trigger with roughly a 5 lb pull for repeatable accuracy. The 5.0-inch barrel and 6.5-inch sight radius support precise sight alignment, and the pistol’s weight of 41.6 oz (with magazine) aids recoil control for follow-up shots.

Calibers and Practical Use

The 1911 STX is offered in multiple chamberings—9mm, 10mm, .45 ACP and .357 SIG—allowing buyers to select the round that matches mission requirements. For tactical defense, .45 ACP delivers proven terminal performance with manageable recoil in this full-size package; with an 8-round magazine capacity in .45 configurations, the platform emphasizes deliberate, accurate shooting. The match-grade barrel and single-action trigger make the STX a strong choice for precision-oriented defensive drills.

Price for the SIG SAUER 1911 STX FULL-SIZE is $1148.99, reflecting the custom-shop fit and premium components. View product details and pricing
