Heckler & Koch Jet Funnel Kit USP 9mm Luger and 40 Smith & Wesson

The Heckler & Koch Jet Funnel Kit for USP 9mm and .40 S&W pistols is a straightforward upgrade for shooters who want to shave seconds off reload drills at the range or in competition. Built to fit full-size USP models in both calibers, this enlarged magazine well turns fumbling mag changes into smooth, confident reloads. Whether you're working on speed at an IPSC match, running drills on your own time, or just tired of hunting for your magazine in the magwell, the Jet Funnel removes friction from the process.

H&K engineered this funnel to complement the USP's already-solid ergonomics without overcomplicating things. It's a single-purpose tool that does one job well: open up the magazine well enough that you can load faster, even under pressure or low-light conditions. No springs, no levers, no unnecessary bells—just a wider funnel mouth that lets your muscle memory take over.

If you're running 9mm or .40 S&W in a full-size USP and you've ever lost half a second fishing for the magazine hole, this kit is worth the money. Reloading is one of the easiest fundamentals to improve, and a Jet Funnel makes the improvement immediate and reliable.
