Check Mate Staccato 2011 Handgun Magazine Stainless Steel 9mm Luger 17 rd CM9 2011 126 S UPC 850020492671
Product Description
The Check-Mate Staccato 2011 17-Round 9mm Stainless Steel Magazine (MPN: CM9-2011-126-S) is a premium double-stack 126mm magazine purpose-built to deliver extreme feeding reliability, structural endurance, and flawless lockup in Staccato and 2011-pattern high-capacity handguns. Precision-engineered in the USA from ultra-durable, high-grade 300-series stainless steel, this magazine is through-hardened and polished to withstand the grueling demands of USPSA/IDPA competition, duty service, and tactical training.
Featuring a proprietary anti-tilt polymer follower, high-tensile music wire spring, and precision-formed feed lips, the CM9-2011-126-S eliminates nose-diving, double-feeding, and rim-bind when cycling high-velocity 9mm defensive hollow points or target FMJ loads. The 126mm tube length sits flush or slightly recessed depending on the specific 2011 magwell, providing a standard 17-round capacity in a compact, duty-ready form factor.
Equipped with an impact-resistant polymer base pad for drop-free speed reloads and dual side witness holes for quick visual round counts, Check-Mate’s 2011 magazine offers shooters an ultra-reliable, high-value alternative to standard factory double-stack magazines. Backed by Check-Mate's legendary USA manufacturing standards, it is built to run hard in modern double-stack 1911/2011 platforms.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits Staccato 2011 pistols (Staccato C2, P, XL, XC with appropriate magwell configurations) and standard double-stack 2011-pattern frames (Springfield Prodigy, Bul Armory SAS II, SPS, Atlas Gunworks, and custom 2011 builds chambered in 9mm). (Note: Standard 126mm length sits flush in Staccato C2/P full-size grip modules without extended magwells; magwell-equipped competition setups may require extended 140mm magazines for tool-free seating).
- Perform a complete firearm safety check: drop the installed magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- To load, press 9mm cartridges firmly down and rearward against the follower, ensuring each round seats completely against the rear stainless steel wall.
- Inspect the numbered side witness ports to visually verify cartridge count (up to 17 rounds).
- Insert the magazine firmly into the 2011 magwell until the frame magazine catch engages with a distinct, crisp tactile click.
- Depress the magazine release button during dry reload drills to verify smooth, drop-free ejection under its own weight.
