Description

The H&K Jet Funnel Kit turns your USP into a faster-reloading platform. If you're running a full-size USP in 9mm or .40 S&W and serious about competition or practical shooting, this magwell assembly delivers measurable speed gains when it counts. The enlarged magazine well features a deep bevel that naturally funnels rounds into the grip, taking the guesswork out of reloads under pressure.

What makes the Jet Funnel different from other magwells

This isn't just a larger hole. The geometry is purpose-built by H&K engineers who understand that reload speed means nothing if the magazine doesn't seat fast and reliably. The funnel design guides magazine presentation without requiring extra hand movement, which adds up over hundreds of repetitions at the range or in competition. The kit ships as a complete assembly with all necessary hardware, so you're not hunting for parts that fit.

Installation and what you need to know

No gunsmithing required. The kit installs with basic tools and included hardware in minutes. One important detail: once installed, you must use Jet Funnel magazines (18-round 9mm or 16-round .40 S&W) because standard USP magazines won't fit flush in the enlarged well. The funnel can be removed just as easily if you need to swap back, taking about five seconds with the correct hex key. If flexibility between magazine types matters to you, factor this in before installing.

Build quality you expect from Heckler & Koch

Constructed from steel with a black finish that matches factory aesthetics. The magwell is manufactured in Germany and built to take years of use without wear or failure. This is German precision applied to a straightforward accessory, which means it works the way you expect and doesn't require babying.

Frequently Asked Questions

Can I still use my standard 15-round USP magazines with the Jet Funnel installed?

No. Once the Jet Funnel is installed, you must use Jet Funnel magazines (18-round for 9mm or 16-round for .40 S&W). Standard magazines won't fit properly in the enlarged well. You can remove the Jet Funnel in about 5 seconds with the included hex key if you need to swap back to standard magazines temporarily.

Is this Jet Funnel Kit compatible with my USP Compact or USP Tactical .45?

This kit is designed for USP full-size models in 9mm and .40 S&W only. It won't work with compact models, and no .45 caliber Jet Funnel magazines exist for the .45 USP platform. Check your pistol's chamber marking and frame size before ordering.

Will the Jet Funnel actually improve my reload speed?

Yes. The deep beveled funnel guides the magazine into the grip with minimal hand manipulation, which measurably reduces time between shots in timed drills and competition. Most users report faster, more consistent reloads, especially during high-pressure scenarios. Results depend on practice, but the design removes friction from the reload process.

How difficult is it to install the Jet Funnel Kit?

Installation requires no gunsmithing or modifications. The kit includes all hardware and comes with a hex key. Most shooters complete installation in minutes. If you prefer professional installation, any qualified gunsmith familiar with H&K pistols can handle it, though it's designed for straightforward DIY assembly.
