Fits: Heckler & Koch USP
This 20-round magazine is purpose-built for the Heckler & Koch USP Full Size pistol in .45 ACP, offering shooters extended capacity for training, competition, or defensive use.
ProMag engineers this magazine with the same attention to detail found in quality firearms. The magazine body is constructed from heat-treated blued steel that resists corrosion and wear. The follower uses a proprietary DuPont Zytel-based polymer designed for long service life and consistent feeding.
The magazine spring is precision-wound from heat-treated chrome-silicon wire—the same material used in quality firearm springs. Every component is inspected and double-checked during assembly to maintain consistent quality.
Backed by a lifetime guarantee against manufacturer defects. ProMag stands behind their products because they're built to last.
