Heckler & Koch Original Factory USP45 12-Round Magazine - .45 ACP Caliber, Heavy-Gauge Steel Body, Polymer Extended Finger Rest Baseplate, Heat-Treated Spring, High-Traction Follower, Blued Black Finish - 50248618 / 642230266810
Product Description
Equipping a classic full-size HK USP .45 ACP handgun, staging a tactical duty rig, or building out a reliable combat loadout requires factory original magazines manufactured to Oberndorf's stringent mechanical tolerances. Aftermarket or worn magazines often exhibit weak spring tension, feed lip deformation, or awkward grip engagement that compromises cycling and hand placement on your bench. The **Heckler & Koch® Factory Original USP45 12-Round Magazine with Extended Finger Rest (50248618 / 642230266810)** flatlines these feed and grip limitations, delivering a full **12-round .45 ACP capacity** paired with an ergonomic extended floorplate.
Proudly engineered and manufactured in Germany by Heckler & Koch, this genuine factory OEM magazine features a heavy-gauge, cold-formed **steel body** protected by a durable blued anti-friction coating. Internal feeding is driven by a precision heat-treated steel spring and a polymer anti-tilt follower designed to present cartridges smoothly into the chamber under rapid fire. The highlight feature is HK's factory **extended polymer finger rest floorplate**, which extends forward to support your pinky finger—significantly enhancing recoil control and grip stability without adding awkward bulk. Designed for seamless insertion into full-size HK USP45 and USP45 Tactical handguns, this turn-key magazine delivers ultimate feeding performance straight from your armorer bench.
Engineered to slide cleanly into standard HK USP45 full-size magwells, this factory-calibrated steel magazine guarantees absolute feed reliability directly from your workspace bench.
*Armorer Bench Notes & Real-World USP45 Staging Guidance: The HK 50248618 factory magazine arrives workspace ready as a pre-assembled 12-round steel feeding unit complete with the extended finger rest baseplate. HK USP .45 ACP HOST PLATFORM INTERFACE MATRIX: This magazine is engineered natively, strictly, and dimensionally to fit full-size **HK USP45 and USP45 Tactical handguns**. *Compact & Mark 23 Compatibility Checklist:* This magazine is designed specifically for standard full-size USP45 frames—it will *not* seat inside HK USP Compact .45 models (which use shorter magwells) or the HK Mark 23 / HK45 series without physical floorplate interference. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host USP45 handgun is completely clear of live ammunition, the magazine is removed, and the chamber is checked safe and empty. 2. Inspect the feed lips and rear witness holes (numbered 2 through 12) to ensure no transit oils or debris obstruct follower tracking. 3. Load up to 12 rounds of standard or heavy-grain .45 ACP ammunition into the double-stack body, ensuring each case rim rests flush against the rear spine. 4. Insert the loaded magazine firmly into the magwell until the ambidextrous paddle catch locks with a distinct metallic click. 5. Verify that your grip pinky finger rests comfortably on the front lip of the extended polymer floorplate. 6. Manually cycle the slide to verify smooth cartridge pickup from the feed lips before rolling downrange.*
