The ProMag HECA2 is a 20-round magazine purpose-built for the H&K USP .45 ACP pistol. If you're running a USP and want reliable extra capacity for the range, competition, or duty use, this steel magazine delivers straightforward functionality backed by American manufacturing. ProMag magazines are made in the USA and come with a lifetime guarantee against manufacturer defects—a solid commitment to standing behind their product.
What sets ProMag apart is attention to the fundamentals. The magazine springs are precision-wound using heat-treated chrome silicon wire, the kind of material choice that resists fatigue and maintains consistent feeding pressure over thousands of cycles. Every step of assembly gets checked and double-checked, which matters when reliable feeding is non-negotiable. The included grip sleeve helps you manage the larger footprint of a 20-round magazine, keeping your grip comfortable and controllable even during extended range sessions.
Built from steel with a rugged blued finish, this magazine is designed to take hard use without complaint. At 20 rounds, you're doubling the standard capacity of most USP .45 magazines, which makes a real difference if you're working through drills or stocking up for an action-packed day at the range. The straightforward design loads easily, and the steel construction resists damage from drops and rough handling that would compromise lesser magazines.
