Heckler & Koch® Genuine Mark 23 / MK23 .45 ACP Factory Magazine – 12 Rounds – Steel Black – 215668S
The Heckler & Koch® Genuine Mark 23 / MK23 .45 ACP Factory Magazine (215668S) is a premium, military-spec feeding component engineered explicitly to deliver flawless operational reliability inside the legendary HK Mark 23 offensive handgun platform. While third-party options or unreinforced aftermarket alternatives frequently suffer from soft feed-lip distortion, inconsistent follower binding, and spring fatigue under prolonged compression, this authentic factory masterpiece completely eliminates those mechanical vulnerabilities. This high-capacity 12-round magazine (642230244030) is built to the exact deployment standards required for professional field work, providing an unyielding insurance policy for duty use, home defense setups, and collector firearms.
Precision-formed in Germany from high-tensile, heavy-gauge heat-treated structural steel, the body of the 215668S features a proprietary, friction-reducing matte black corrosion-resistant finish. This specialized coating preserves seamless surface tracking while shielding the underlying metal matrix against coastal salt spray, sweat acids, and harsh carbon fouling. The technical core of this authentic HK magazine utilizes a heavy-duty, high-tensile steel wire spring coupled with a smooth-glide, high-density polymer anti-tilt tracking follower, ensuring uniform upward force directly against the receiver's breech face. Completed with standard rear-facing witness tracking holes for immediate round verification and an impact-resistant polymer floor plate, this 12-round powerhouse matches the uncompromising, match-grade feeding dynamics that made the "SOCOM Pistol" globally famous.
Includes: (1) Heckler & Koch Mark 23 .45 ACP 12-Round Factory OEM Steel Replacement Magazine with High-Impact Polymer Basepad.
*Compatibility Note: This factory magazine is custom-dimensioned EXCLUSIVELY to fit the oversized grip frame of the official Heckler & Koch Mark 23 (.45 ACP) platform. It is NOT compatible with alternative HK .45 caliber handguns, including the USP45, USP45 Compact, HK45, or HK45 Compact, which utilize entirely different frame and latch geometry.
