Double Stack Handguns

Wilson Combat double stack 1911 handguns represent over four decades of engineering excellence and innovation in custom pistol manufacturing. Unlike competitors who simply widen existing frames, our approach involves ground-up engineering to create truly superior custom double stack handguns.

The Enhanced Reliability System (ERS) is tailored to the varying power levels of 9mm ammunition and maintains impressive reliability in all conditions, even when heavily fouled and low on lubrication. This system addresses the unique challenges of chambering 9mm cartridges in a 1911 platform, ensuring consistent performance across all ammunition weights and power levels.

Our solid frame construction process begins with precision-machined aluminum blocks, creating frames that are more robust than modular designs while remaining lightweight for extended carry. This manufacturing approach ensures dimensional stability and long-term durability that sets Wilson Combat apart from mass-produced alternatives.

Every Wilson Combat double stack pistol undergoes extensive hand-fitting by master pistolsmiths, ensuring optimal performance with a wide variety of ammunition types. Wilson Combat custom handguns have won more pistol competitions and have been carried in more duty holsters than any other custom pistol brand.

Wilson Combat's Enhanced Reliability System (ERS) is a proprietary system designed to optimize functioning with the varying power levels of 9mm ammunition. This system addresses the unique challenges of chambering 9mm cartridges in a 1911 platform, ensuring consistent performance across all ammunition weights and power levels.

The ERS incorporates several key innovations:

• External Extractor Design: Unlike traditional internal extractors that can be sensitive to timing, our external extractor provides more positive case extraction and ejection, particularly important in high-volume shooting scenarios.

• Optimized Chamber Geometry: Hand-fitted chambers ensure consistent headspace and optimal cartridge positioning for reliable ignition and extraction cycles.

• Reduced Frame Rails: Strategic rail reduction enhances magazine feeding while maintaining structural integrity, allowing smooth cartridge presentation to the chamber.

• Match-Grade Barrel Integration: Each barrel is individually fitted and timed for optimal lockup, contributing to both accuracy and reliability performance.

These pistols feed from a double-stacked magazine, and the real innovation is the grip frame design that incorporates a one-piece backstrap, further enhancing reliability by eliminating potential failure points. This comprehensive approach to reliability engineering has made Wilson Combat double stack 1911 handguns the choice of professionals who demand unfailing performance.

• What makes Wilson Combat double stack 1911s more reliable than standard 1911 pistols?

  The 1911 was designed for .45 ACP, which has different chamber pressure and size than 9mm. This can cause cycling, extraction, and feeding issues when simply chambering a traditional 1911 in 9mm.

  Wilson Combat's Enhanced Reliability System (ERS) solves this with external extractors, optimized chamber geometry, and hand-fitted barrels specifically engineered for 9mm functionality. Our solid frame construction and master gunsmith fitting ensure consistent performance with all ammunition types.

• How do Wilson Combat double stack pistols compare to single stack 1911s?

  Wilson Combat double stack 1911s offer 15-18 round capacity vs. 7-8 rounds in single stack models. The grip is wider but Wilson Combat engineering minimizes this difference while maintaining familiar 1911 controls and trigger feel.

  In competition, the larger magwell provides faster magazine changes. Shooters easily transition from single to double stack while gaining significant capacity for competition, duty, or defense use.

• What customization options are available for Wilson Combat double stack handguns?

  Extensive customization options include multiple finishes (Armor-Tuff, Combat-Tuff, stainless, bluing), sight configurations (fiber optic, tritium, adjustable, optics-ready), trigger options, and grip textures (X-Tac, checkering, smooth).

  Frame modifications like integrated magwells, accessory rails, and specialized cuts are available. Division 77 models showcase our most advanced customization capabilities in limited quantities.
