There is little doubt that weapon mounted tactical flashlights are an all important accessory for urban combat. GG&G manufactures twelve different tactical flashlight adapters and mounts for various weapon systems including the GG&G USP adapter. There is also little doubt that the HK USP handgun is one of the ten best handguns manufactured. Unfortunately, HK chose to manufacture the dust cover integral mounting rail to only accept the URL flashlight. Besides being very expensive, large and heavy, the URL lacks the flexibility to be mounted to other weapon systems. GG&G has engineered a HK compact flashlight mounting rail adapter for Streamlight TLR-1/2 AND ITI M3/M6 flashlights.

Our highly regarded design engineering staff developed an innovative and clever mount to interface the TLR-1 and 2 and M3/M6 with the USP standard and compact handguns in a small and lightweight package. As can be seen in the photographs, the GG&G Slim Line USP Flashlight Mount fits tightly to the USP trigger guard allowing the TLR and M series rear rocker switches to be activated by the fire control finger or the thumb of the off hand. The Slim Line USP Flashlight Mount rail adapter is available for the full-size and compact USP handguns in 9mm, .40 and .45 calibers.

The GG&G Slim Line USP HK Flashlight Mount consists of a three piece lightweight aluminum adapter that easily clamps over the existing USP light rails. The installation only requires a small wrench. The rail fits tight enough to retain zero of the TLR-2 and M6 laser. The GG&G Slim Line USP Flashlight Mount is machined from solid billet 6061 T6 aircraft-grade aluminum alloy using modern CNC machinery. It is then Type III hard-coat anodized matte black per mil-spec for combat durability.
