4 Best HK USP Light Options [New Products]

We have narrowed down 4 best HK USP light options.

All recommended lights were purchased and used for a very long extend time on the HK USP and other handguns before putting them on this guide.

Our recommendations are based on practical use, lumen output, activation switches, size and price. Knowing that the HK USP doesn't feature a standard pic rail to mount lights, please be sure to get the HK USP Rail Adapter to accept these lights recommended.

Check them out below:

Streamlight TLR 1 HL - Best Overall

Why Get The TLR 1 - The Streamlight TLR 1 is used on most law enforcement officer's duty pistol setup. It's by far the most popular duty grade pistol weapon light for HK USP besides the Surefire X300 or XH30.

Upgraded With More Lumen - Now up to 1000 lumens with the HL version with much brighter illumination & throw

Wide Illumination - Search & ID subjects in the dark with a wide beam coverage area without having to point the muzzle directly towards the target of interest

Easy Toggle Switch - Much easier to press the switch for activation around the large USP trigger guard. Easy two handed and one handed operation.

Serviceable Lens Bezel - Saves money replacing just the bezel instead of the whole light after  force on force simunition training damage.

Strobe Mode Added - Dobule tap to activate the strobe to blind threats and other tactical moves in low light

Features:

• 1000 Lumens
• 15000 Candela
• 2 CR123A Batteries
• 4.18 oz
• 3.39 in
• IPX7

Surefire X300U - 2nd Best Duty Light

Why pick this one - The Surefire X300U with the thumb screw mount is highly recommended to mount on the USP rail adapter. Surefire makes some of the world's best weapon light accessories, and the X300U goes very well with the old school USP EXPERT 9mm long slide.

Balanced Throw & Spill - TIR lens provides a hot spot and wide illumination like the TLR 1 to illuminate far away and also ID things in low light. 

Slide Always In Battery - Extra light bezel length over the muzzle prevents the slide from getting out of battery during point blank muzzle-to-surface contact engagement, or use as a striking device

Mounts Directly To The Rail - Adjustable tension 

Built To Last - Mil-spec grade aluminum housing protects electronic components inside from sharp recoil impulse, drop, and day to day field handling.

Highly recommended - SUREFIRE DG SWITCHES for shooters that can't easily reach the toggle switch 

Features:

• 1000 Lumens
• 11300 Candela
• 2 CR123A Batteries
• 4.8 oz
• 3.7 in
• IPX7

Streamlight TLR 7A Flex - Best Compact

Streamlight TLR 7A Flex fits flush with the muzzle of the HK USP non threaded barrel. It's a great compact pistol lights that works great and looks slick on the USP full size. 

See All Around You - Illuminate up to 40 yards in low light for night shoot, search & personal defense

Adds Only 2.4 Oz - Runs on only 1 CR123A battery (50,000 hours) that can produce up to 500 lumens & 5000 candela

Slim Profile - Doesn't stick out past below the USP trigger guard frame unlike other large size lights

Responsive Ambi Control - Works For Lefties & Righties (Better toggle switch reach wanted)
