Heckler & Koch USP 9mm Luger 18rd Magazine Clear

The Heckler & Koch USP 9mm Luger 18-round clear magazine is a high-capacity factory original designed to feed your full-size USP 9mm handgun reliably. Whether you're running drills at the range, training for defensive carry, or stocking spares for your duty setup, this H&K magazine gives you the round count and visibility you need. The clear body lets you see remaining ammunition at a glance—no guessing when you're running low during practice or competition.

H&K engineered this 18-round magazine for USP 9mm full-size models, and it'll drop right in without modification. The magazine works with or without the optional Jet Funnel mag well installed. If you're running a standard USP without the funnel, be aware the magazine will extend below the magazine well—not a functional issue, just something to know about your setup. With the Jet Funnel kit in place, you get a flush fit.

Factory OEM magazines are the backbone of any reliable handgun system. This is the real deal from H&K, not an aftermarket clone. If you shoot a USP 9mm, having multiple factory mags on hand is non-negotiable. The clear polymer construction is durable and lets you quickly verify mag status in the field or on the range.
