EAA® Witness 2311 Factory 17-Round 9mm Double-Stack Magazine – Premium Stainless Steel Tube – High-Tensile Spring – Polymer Baseplate – Made by Check-Mate – 111002
Product Description
The EAA® Witness 2311 Factory 17-Round 9mm Double-Stack Magazine (111002) represents an elite, high-performance mechanical benchmark in modern double-stack 1911 and 2011 handgun platforms, masterfully manufactured by Check-Mate Industries to optimize feeding logistics and ammunition delivery metrics. Engineered to serve as a zero-fail primary asset or a high-velocity backup staging component, this factory original equipment manufacturer (OEM) magazine guarantees unyielding structural endurance under high-tempo training and duty environments. While generic aftermarket double-stack magazines often use flimsy sheet metal that bows along the side walls—inducing catastrophic failure-to-feed (FTF) bugs, crushed feed lips, and erratic follower tilt—the EAA Witness 2311 magazine is built to rigorous defense tolerances. This heavy-duty steel asset (741566906145) provides an indispensable foundation for competitive shooters, tactical operators, and personal defense enthusiasts alike.
The core structural backbone of this 17-round high-capacity engine is precision-formed from a single premium piece of heavy-gauge stainless steel alloy. This robust metallic matrix handles immense internal compression forces without stretching or expanding, preventing friction points against the host handgun's internal magwell. To defeat the corrosive effects of sweat acidity, heavy downpours, and carbon blowback during suppressed operations, the exterior is completed with a smooth, low-friction protective coating. This advanced chemical surface layer guarantees lightning-fast, drop-free mechanical gravity transitions during intense tactical reloads. The interior movement track is powered by an overbuilt, high-tensile heat-treated steel wire compression spring paired with a low-drag, anti-tilt polymer follower, establishing uniform upward pressure to ensure clean, flat-line presentation into the chamber face across every single cycling loop.
The true operational triumph of this American-built adaptation lies in its exceptional cross-platform design symmetry and field-ready handling geometry. Tailored natively to fit the **EAA / Girsan Witness 2311 pistol lines**, this magazine features optimized feed lip vectors that cross-map beautifully to a wide array of standardized double-stack 2011 and 1911-derived competition frames chambered in 9x19mm Parabellum or .38 Super. The base is anchored by a high-impact, shock-absorbing polymer floorplate designed to take the brute force of drop impacts onto concrete or hard terrain. This removable baseplate allows tool-free disassembly for rapid maintenance routines. Holding a robust 17-round operational payload, this factory-original powerhouse grants you absolute structural and feeding authority over your defensive sidearm workspace.
Includes: (1) Authentic EAA Witness 2311 OEM 17-Round 9mm Double-Stack Stainless Steel Magazine Assembly (Low-Friction Coated Body, High-Tensile Internal Wire Spring, Anti-Tilt Follower, Impact-Resistant Polymer Baseplate), Packed in Original Factory Branded Sealed Protective Retail Packaging.
*Administrative Staging, Compatibility & Compliance Guidance: The EAA 111002 magazine is configured specifically for double-stack Witness 2311 models and standard-pattern 2011/1911 double-stack 9mm frames; it is completely incompatible with single-stack 1911 handguns or classic single-stack EAA Witness/Tanfoglio CZ-pattern frames. To maintain optimal cycling velocity across long deployment periods, periodically clear out accumulated carbon scale or trail dust from the inner casing using a dedicated nylon mag brush. **JURISDICTIONAL RESTRICTION WARNING:** This magazine features a high-capacity 17-round footprint and cannot be shipped to municipalities with strict 10-round or 15-round maximum capacity limits. Always visually and physically verify that your handgun frame is completely unloaded, cleared, and verified safe before executing magazine bench cleanings or parts swaps.
Key Features
- OEM Check-Mate Engineering: Fabricated by Check-Mate Industries to exact original manufacturer tolerances for seamless, drop-free integration with the Girsan Witness 2311.
- Premium Stainless Steel Casing: Heavy-gauge stainless steel tube prevents side-wall deformation, feed-lip spreading, and physical body bowing under full spring load.
- Low-Drag Anti-Tilt Follower: Injection-molded polymer follower guarantees perfectly concentric cartridge alignment, eliminating tilt-induced nose dives during feeding sequences.
- High-Tensile Steel Wire Spring: High-endurance tempered spring resists memory set over extended staging periods, delivering uniform tracking force to the very last round.
- Impact-Resistant Polymer Floorplate: Shock-buffering baseline cap handles aggressive tactical reloads and concrete drops while removing easily for tool-free field strips.
- Universal 2011 Cross-Compatibility: Precision dimensional profiling maps smoothly to multiple modern double-stack 1911 and 2011 modular grip systems chambered in 9mm.
