Easy and Tactile Toggle Switches: Switching this sight on is easy. You don’t have to apply a ton of pressure to activate the light. This comes in handy in freezing conditions where your fingers might not be at their best. 

Whether you’re wearing gloves or not, the toggle switches are responsive and easy to manipulate.

Replaceable Lens Bezel: Accidents happen, especially during intense force-on-force simulation training. The lens can take a beating, but here’s the kicker: you can replace just the lens bezel instead of buying a whole new light. 

Strobe Mode Added: This feature isn’t just a gimmick; it’s a tactical asset. The fast strobe can disorient threats, giving you a split-second advantage. It can make all the difference when the situation gets dicey.

Why I love it: What’s not to love? It’s affordable, it’s dependable, and it offers features usually found in pricier models. The Streamlight TLR-1 HL ticks all the boxes for what I need in a reliable firearm light.

My Experience 

This light fits the Glock 45 like a glove. Mounting and demounting were hassle-free. The high lumen and candela output were exceptional during my nighttime drills. 

The tactile switches came in clutch during cold weather tests. Overall, this light didn’t just meet my expectations; it surpassed them.


  • Very affordable
  • Duty-grade light
  • High lumen & candela output
  • Easy to mount and demount
  • Easy-to-toggle switches for one-handed use


  • Still relies on 2 CR123A batteries

The ideal compact and lightweight light for your Glock 45, perfect for quick holster action.

Super Lightweight: One of the first things you’ll notice about the TLR-7A is how incredibly light it is. We’re talking just a touch over 2 ounces! Whether you’re carrying concealed or on duty, this will make a noticeable difference in comfort and maneuverability.

Bright Light Beam: Don’t let its size fool you; this compact unit can light up a room. A single CR123A battery blasts out 500 lumens and 5000 candela. It’s more than enough illumination for close-quarters situations.

See All Around You: Visibility is critical, and the TLR-7A delivers. In dimly lit environments, you’ll have a clear line of sight for about 30-40 yards. Its wide beam allows you to catch details in your peripheral vision between the 9 and 3 o’clock positions.

Great for CCW: The compact size and length perfectly match the Glock 45’s barrel. It won’t protrude awkwardly or snag when you’re drawing it from a holster.

Responsive Ambi Control: Left-handed? Right-handed? No problem. The TLR-7A has ambidextrous controls that are responsive and intuitive, making it super easy to operate with either hand.

Why I love it: It’s compact, it’s bright, and it’s versatile. This light has found the sweet spot between size and performance, and it’s just what my Glock 45 needed.

My Experience 

I’ve put this light through its paces, and it’s come out shining—literally. The beam is bright, the controls are easy, and the weight is negligible. It fits seamlessly with my Glock 45 and makes for a sleek and effective setup.


  • Same performance as TLR-7A but in a smaller package
  • Non-snag profile perfect for concealed carry


  • Strobe activation can be a bit tricky to figure out

3. Surefire X300U – Good Throw

A robust and versatile upgrade to the classic X300U, designed to handle the most demanding situations with your Glock 45.

Slide Always In Battery: The XH30 has a fascinating design feature where the light passes beyond the Glock 45’s barrel. 

This acts as a support structure and prevents the slide from jamming or getting out of battery during point-blank engagements. 

Strobe Mode Added: The XH30 comes with a built-in strobe mode that can disorient threats effectively. If you need to gain a tactical advantage quickly, flipping on the strobe can make a world of difference.

Balanced Throw & Spill: This light offers a balanced approach to illumination. You get a focused “hot spot” for targeted lighting and a wide beam for overall visibility. Make sure you opt for the XH30 model for this feature; it’s not in the XH35.

Mounts Directly to The Rail: Let’s talk about ease of use. The XH30 comes with a Glock rail key included, ensuring it fits perfectly with your Glock 45. Mounting and demounting are as simple as it gets.

Built to Last: The XH30 is constructed with the same attention to durability as the original X300U. This light is made to endure and function reliably when you need it the most.

Why I love it: It’s the details for me—the slide support, the balanced throw, and spill, the built-in strobe. All of these features come together to make an outstanding product.

My Experience 

I’ve rigorously tested the XH30, and it has exceeded my expectations. The slide support works flawlessly, keeping everything in battery even during close engagements. The illumination options are versatile, making them adaptable for any scenario.


  • Duty-grade, robust build
  • Versatile illumination options
  • Quick and easy to mount
  • Features a strobe mode


  • The control switches could be more responsive
  • Doesn’t fit the existing X300U holsters
  • Pricier compared to the TLR-1

An eco-friendly, high-lumen light ideal for extensive low-light training with your Glock 45.

High Lumen: The Olight PL Pro packs a punch in the illumination department. With a lumen range from 300 to 1500, this light is on par with some of the most powerful tactical lights out there. Whether you’re training at home or at the range, you’ll get the visibility you need.

QD Lever Mount: Mounting this light is a breeze. The quick-detach lever mount comes with a GL rail key included, so no tools are required for installation or removal. It’s a nice touch that streamlines the entire process, saving you time and hassle.

Positive Control: The activation control switch on the PL Pro is incredibly responsive, even when you’re wearing gloves. No fumbling around to get the light on; it’s a smooth operation through and through.

Unlimited Battery: What really sets this light apart is its USB rechargeable batteries. There is no need to constantly buy new batteries. Just plug it in, charge it up, and you’re good to go. This feature makes the PL Pro cost-effective and great for high-volume use.

Why I love it: The USB rechargeable batteries are a game-changer for me. It’s cost-effective and incredibly convenient, especially for someone who uses their light often during training.

My Experience 

I’ve given the Olight PL Pro a good run during multiple training sessions. The light holds up well, providing consistent, bright illumination. The QD lever mount and positive control features worked seamlessly, even in stressful, rapid-move scenarios.


  • USB rechargeable, saving you money in the long run
  • Simple and quick to mount and demount
  • Exceptional brightness suitable for training scenarios


  • Compatible holsters are hard to come by
  • Requires a two-button press for strobe activation
  • Not recommended for duty use

Affordable, compact, and incredibly bright, this light is a stellar budget option for Glock 45 owners.

Adjustable Rail: The OLIGHT PL-Mini 2 Valkyrie has a patented adjustable rail that lets you slide it along to find the most comfortable and functional position on your Glock 45. Trust me, once you find that sweet spot, your accuracy and comfort will thank you.

Huge Performance: Don’t let its affordable price tag fool you; this light is a powerhouse. With 600 lumens and a throw of 100 meters, you’re getting a lot of bang for your buck. 

This makes it great for identifying targets in less-than-ideal lighting conditions.

Convenient Magnetic Charging: The charging system is magnetic, so there is no fumbling with tiny ports. Just attach the magnetic end to the light, and you’re good to go. It’s so easy, and it also extends the life of the light by reducing wear and tear on the charging port.

Quick Install and Removal: Installation and removal are almost instantaneous. You don’t need any special tools or additional parts. Time is of the essence, whether you’re in a tactical situation or just at the range, and this feature is a lifesaver.

Why I love it: It’s the affordability for me. You’re getting an insane amount of value here, from the adjustable rail to the strong 600-lumen output, all without breaking the bank.

My Experience 

I’ve been running this light through various shooting scenarios, from range practice to low-light situations. It consistently performs above my expectations, especially considering its price point. The magnetic charging and quick install features also proved super useful.


  • High lumen output despite being budget-friendly
  • The magnetic charging system is convenient and easy to use
  • Quick install and removal, no tools required
  • Durable and reliable in various conditions


  • Short battery life on the highest setting, clocking in at around 1 hour 20 minutes

Final Verdict 

So there you have it, folks. After countless hours on the range and many drills in low-light conditions, my top pick has to be the Streamlight TLR-1 HL. 

While each light on this list brings something to the table, Streamlight TLR-1 HL manages to provide an impeccable balance of brightness, durability, and cost-efficiency. Keep in mind, what works best for me might not be your first choice. 

It all boils down to your personal needs and preferences. But if you’re on the fence, you can’t go wrong with this one.
