MG CG4510A MAG COLT GOV 45A 10RD AF - MGCG4510A - 765595112056
Product Description
Single-stack 1911 handguns chambered in .45 ACP are traditionally limited by low 7- or 8-round magazine capacities, requiring frequent reloads during high-volume competition, defensive training, or range drills. Furthermore, low-quality extended magazines often suffer from feed-lip spreading, nose-diving on the top round, or stiff insertion friction inside tight magwells. The Mec-Gar Colt 1911 Government .45 ACP 10-Round Extended Magazine (MGCG4510A) eliminates these capacity and feeding bottlenecks by pairing an extended 10-round tube profile with Mec-Gar's high-lubricity Anti-Friction (AF) coating.
Engineered by Mec-Gar—the world’s premier firearm magazine manufacturer—this full-size 1911 magazine is constructed from heat-treated carbon steel. The specialized Anti-Friction surface treatment reduces internal and external drag, shielding the body against rust and corrosion while ensuring rapid, slick drops during emergency mag changes. The single-stack body extends slightly beyond the grip frame and is fitted with an impact-resistant polymer sleeve and baseplate, providing smooth indexing and protecting against floor drop damage.
Driven by a high-tensile music wire spring and a smooth-sliding, anti-tilt steel follower, the Mec-Gar MGCG4510A provides 10 rounds of continuous .45 ACP firepower. Engineered for seamless lockup in standard 1911 Government and Commander receivers, it delivers competition-ready reliability and duty-grade cycling performance.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment & Compatibility Matrix: Fits single-stack 1911 Full-Size Government and Commander pattern frames chambered in .45 ACP (e.g., Colt, Springfield Armory, Kimber, SIG Sauer, Rock Island Armory, Ruger SR1911). Note: Will extend past the flush grip frame on Compact / Officer-size 1911s; not compatible with double-stack 2011 / 1911 A2 frames.
Operation & Staging Sequence:
- Safety check the firearm, depress the magazine catch, and visually and physically inspect the chamber to verify an empty weapon.
- Load up to ten (10) .45 ACP rounds straight down into the magazine, ensuring each case head rests flush against the rear spine.
- Insert the magazine firmly into the 1911 magwell until the magazine catch locks with a clear, positive click. The extended polymer sleeve provides a clean grip extension stop.
- For routine maintenance, press the floorplate retention pin and slide the baseplate off to clear debris—do NOT oil or grease internal tube walls.
