Top 5 Best HK USP 45 Lights
1. Streamlight TLR-7A Flex – Best Option
A compact, high-performing light that sits flush with the HK USP 45’s muzzle and adds minimal weight.
Illumination Range: If you’ve ever been in a low-light scenario, you know how crucial visibility is. This light really impressed me by illuminating up to 40 yards ahead.
For night shooting, search missions, or personal defense, the Streamlight TLR-7A Flex ensures you can see what’s happening around you. It’s like having a mini-sun at the end of your barrel.
Light Weight: Adding only 2.4 ounces to your set-up is almost like adding nothing at all. Trust me, those extra ounces can make a difference in a long shooting session or in high-stress situations.
This lightweight design runs on just a single CR123A battery, another perk if you want to keep things simple and efficient.
Slim Profile: A lot of lights stick out like sore thumbs and can snag on holsters or clothing. The slim profile of this light fits beautifully below the trigger guard.
It’s streamlined, slick, and, well, just makes your HK USP 45 look cooler.
Ambi Controls: Are you a lefty? Or a righty? Doesn’t matter. The ambidextrous control features of this light work seamlessly for both.
If I could ask for one improvement, it’d be a slightly better toggle switch reach. But overall, flipping this light on and off is a cinch.
Battery Life and Output: The Streamlight TLR-7A Flex boasts 500 lumens and 5000 candelas while running on a single CR123A battery. It’s got a whopping 50,000-hour life. That’s a whole lot of brightness for a little guy.
Why I Love It: This light ticks all the boxes: it’s light, it’s bright, and it’s efficient. It doesn’t just meet expectations; it exceeds them. And for an experienced shooter, that’s what really counts.
I mounted this light and took it for a spin in various conditions. It never failed to provide crisp, clear lighting. The flush fit with the muzzle means no awkward protrusions, making handling and aiming feel natural.

2. Streamlight TLR-1 HL – Solid Battery Life
The go-to duty-grade light for law enforcement, boasting 1000 lumens and easy operational features.
Brighter Than Ever: Okay, this light is a powerhouse. The HL version brings a massive upgrade in the illumination department, with a staggering 1000 lumens.
During my field tests, it was almost like turning night into day. This light will give you an edge in any low-light situation, ensuring that you can clearly see and identify your target.
Wide Illumination: The Streamlight TLR-1 HL doesn’t force you to point your muzzle directly at whatever you’re trying to look at.
The wide beam pattern is great for scanning areas without making you feel restricted. So, when I was running search and ID drills, this feature made a significant difference.
User-Friendly Toggle Switch: Let’s talk ease of use. The toggle switch is perfectly designed to fit around the larger HK USP trigger guard.
This meant smooth sailing for both one-handed and two-handed operations during my field tests. These little details elevate a good experience to a great one.
Strobe Mode: The addition of a strobe mode is quite useful for disorienting threats in low-light situations. A simple double-tap activates this feature.
I experimented with it on the field, and let me tell you, it’s effective for gaining the upper hand.
Why I Love It: The Streamlight TLR-1 HL goes above and beyond when it comes to performance, usability, and tactical advantages. It’s a robust, dependable light that makes your HK USP 45 even more of a standout.

3. Surefire X300U – Premium Light
A rock-solid, high-performing light that beautifully complements the HK USP, especially the Expert 9mm long slide.
Balanced Throw & Spill: First, this gadget’s lighting is exceptional. The TIR lens offers a balanced throw and spill, almost akin to the TLR-1.
During my field tests, it illuminated far and wide, making target identification straightforward in low-light conditions. It’s not just about the light’s intensity but also the quality of illumination it provides.
Slide Always In Battery: One unique feature I came across is the extra bezel length over the muzzle. What does this do? It prevents the slide from getting out of battery during close-contact situations.
This feature can also serve as a striking device if needed, adding to the light’s versatility.
Built to Last: When we talk about durability, the X300U is up there. Made from mil-spec grade aluminum, this housing is tough as nails.
It safeguards the electronic components inside from sharp recoil impulse, drops, and daily wear and tear.

During my tests, the light could reach up to 225 meters; that’s way more than most typical engagement distances.
On the flip side, its low mode of 200 lumens also makes it versatile for indoor use, so you’re not blinded by the reflection off the walls.
Reliable and Sturdy: I’ve got to hand it to OLIGHT for making a light that’s sturdy as can be. The setscrew is such a simple yet impactful feature, adding to the light’s reliability and toughness.
Ambidextrous Switches: Nothing irks me more than a light that forgets about left-handed shooters.
This light contains a dual-mode setting switch and ambidextrous controls for momentary-on, constant-on, and strobe settings, all accessible by either hand. This inclusiveness won me over.
Why I Love It: What’s not to love? It’s like OLIGHT looked at every issue shooters usually have with weapon lights and decided to resolve them all in one go. The versatility and the attention to detail are just top-notch.
My HK USP 45 and this light are like a match made in heaven. I tested it out during some nighttime shooting and also in a controlled indoor environment.

That’s on par with some of the mid-sized weapon lights out there. In my field tests, this light outperformed its small size in all the right ways. It lit up the target and the surroundings but didn’t overdo it, a balanced act that’s hard to find in a compact light.
Convenient Magnetic Charging: What’s super cool here is the magnetic USB charging system. I didn’t have to remove batteries or fumble with any ports.
Slap on the magnetic connector, and you’re good to go. Believe me, it’s a refreshing change from the regular USB port drama.
Easy-to-Use Switches: I appreciate simplicity when it’s crunch time. The switches on the PL-MINI 2 are super straightforward; press down quickly for constant on/off or hold for momentary-on. No complicated sequences, and no fuss.
Lithium Polymer Battery: The built-in lithium polymer battery is a powerhouse.
It held up well throughout my tests and kept the light running without any hitches. And of course, charging it through the magnetic port was a breeze.
Why I Love It: The PL-MINI 2 is like that scrappy player on the team who doesn’t look like much but surprises you at every turn. From its luminosity to its ease of use, it’s a winner all around.
