Top 5 Best SIG M17 Lights

1. Streamlight TLR-1 HL – Best Overall Choice

It is a robust and versatile weapon light that takes your SIG M17 to the next level of performance and reliability.

That equates to a 283-meter beam, folks! In real-world terms, this means you get crystal-clear visibility in any condition. 

Durability and Construction: Now, onto the durability. Made with durable aluminum and sealed to perfection with an anodized finish, this light isn’t just another pretty piece; it’s built to last. 

With a high-temp, shock-mounted, impact-resistant Boro Float glass lens, the TLR-1 HL can endure rough handling and harsh environments. 

It’s also IPX7 waterproof up to 1 meter for 30 minutes. I put this through the wringer, and let me tell you, it held up like a champ.

User-Friendly Operation: The ambidextrous momentary/steady on/off switch ensures the light is easy to use, regardless of which hand you shoot with. 

This light is powered by two 3-volt CR123 lithium batteries and even comes with a tethered battery door and latch mechanism to prevent battery door loss. How’s that user-friendly?

Whether you’re in a tactical scenario or simply shooting at dusk, the brightness level is astonishing. This is crucial for identifying threats, obstacles, or targets with precision.

TIR Lens: Now, the TIR lens is something special. It creates a smooth and far-reaching light with a larger center spot beam. That means not only can you see what’s directly ahead, but your peripheral vision benefits, too. 

It’s a feature that takes your situational awareness up a notch.

Switching Options: The X300U also has integral ambidextrous momentary- and constant-on switching. 

Whether you’re left-handed, right-handed, or switch, depending on the scenario, this light’s got you covered. Versatility in the heat of the moment is crucial, and this feature delivers.

I’ve run this light on my SIG M17 during several night shooting sessions and a couple of tactical simulations. The LED output made a huge difference in target acquisition. Plus, the battery change was a cinch, even under stress. It lived up to its “premium” tag in every way.

It is a compact, budget-friendly powerhouse offering 600 lumens for a variety of shooting scenarios.

Light Output: Let’s dive into the light output. Boasting 600 lumens, the PL-Mini 2 offers enough brightness for most situations. I’ve tried many lights in this price range, and let me tell you, this one punches above its weight class. 

Whether you’re in your backyard or in a more challenging environment, 600 lumens is more than enough for identifying targets or hazards.

Durability: The next thing that caught my eye was its durability. It’s impact-tested to one meter. I’ve dropped this baby a couple of times while adjusting my settings, and it’s still ticking.

Compact Design: One of the strongest selling points is its compact design. The PL-Mini 2 is a low-profile light, perfect for carrying in tight spaces or adding minimal bulk to your gear. 

If you’re someone who values practicality, you’ll appreciate this feature. Easy to carry, but does the job.

Waterproof Rating: Waterproofing is key for anyone who finds themselves in diverse environments. 

This little guy comes with an IPX6 rating. It held up well during a rainy night session, so it’s reliable come rain or shine.

During my field tests, this was a game changer. If you’re in a space where you need to adjust the brightness based on distance or environment, this light delivers.

Durability: This light is built like a tank, which is especially useful if you’re hard on your gear. I tested the Baldr Pro’s durability by dropping it and banging it against surfaces, and it held up without a scratch. 

So, if you need something that’s going to withstand the rigors of the field, this light is up to the task.

Battery Organizer: A simple yet indispensable feature of the Baldr Pro is its single battery organizer. Believe me, in the heat of the moment, you don’t want to fumble with batteries. 

This feature keeps everything neat and handy. One slot, one battery, no fuss. It’s a small but significant detail that adds to its overall reliability.

Water Resistance: Here’s where it falls a bit short. While this light has a lot going for it, its water resistance isn’t its strongest suit. 

So, if you’re planning on using it in heavy rain or wet conditions, you might want to consider another option.

  • Extremely durable
  • Convenient battery organizer


  • Low water-resistance rating

After much field testing and hours at the range, it’s clear that one light stands head and shoulders above the rest for the SIG M17. That winner is the Streamlight TLR-1 HL. 

Sure, other lights performed admirably;each with its own strengths and areas of expertise. However, the Streamlight TLR-1 HL consistently performed at an elite level under all sorts of conditions, making it my go-to choice.

Your perfect light will, of course, depend on your individual needs and preferences. Some may require a budget-friendly option; others might need a light tailored for rigorous training.
