Wide Field of View: The Trijicon SRO is like looking through a picture window rather than a peephole. Seriously, the field of view is expansive. This generous viewing space grants you the luxury of full situational awareness. 

You can keep tabs on moving targets, be aware of peripheral action, and still maintain pinpoint focus on your primary aim. For those times when long-range accuracy is essential, a larger field of view becomes not just a nicety but a necessity. 

I had the chance to test this and let me tell you, it’s transformative to the shooting experience. I could engage multiple targets much more efficiently, and the sweeping field of view offered me a clear advantage.

Adjustable Brightness Settings: Flexibility is the name of the game with the SRO’s brightness settings. This sight doesn’t tie you down to one level of intensity; it allows real-time adjustments. 

The result? An aiming dot that’s visible, whether you’re under the glaring sun or the dimming light of dusk. During my tests, I found myself easily rotating through different brightness levels to match the ambient conditions, ensuring the dot was neither too glaring nor too dim for optimal aiming.

Lock-In Mode: Now, here’s a feature you’re going to adore. How many times have you had to readjust the dot in the middle of a shot? It’s distracting, right? With the SRO’s lock-in mode, that’s a thing of the past. 

Click it on, and the dot stays put, allowing you to take aim without the worry of the sight losing its zero. This feature feels like a lifeline when you’re shooting at extended ranges. 

During testing, this eliminated all the last-second scrambling, giving me the peace of mind to focus entirely on my shooting technique.

Be it torrential downpours or the unfortunate accidental drop, this sight’s build quality keeps the worries at bay. 

Through various trials, I exposed it to mud, rain, and even a couple of accidental bumps; it remained unscathed and performed without a hitch.

Why I Love It: Among its many standout features, its versatility is the one that steals the show for me. It delivers across multiple shooting environments, making it the perfect match for my Glock 45 MOS.

Large Field of View: You’ve got to love the generous field of view on this sight. In fast-paced situations where split-second decisions are needed, that wider viewing area comes in really handy. 

Tracking targets over long distances becomes significantly easier, allowing for quicker and more accurate shots. Whether you’re a hunter or a competitive shooter, the large field of view will make a noticeable difference in your shooting experience.

Adjustable Brightness Settings: The RMR Type 2 doesn’t skimp on customization. The adjustable brightness settings allow you to adapt to your lighting conditions. 

This sight has got you covered from the glaring midday sun to the dim light of dusk. Simply toggle through the settings to find the one that suits your needs, and you’re good to go.

Sturdy Aluminum Housing: Here’s where design meets function. The lightweight aluminum housing not only adds to its ruggedness but also ensures that it doesn’t add unnecessary weight to your Glock 45 MOS. 

This makes it easier to aim without affecting the balance of your firearm.

Why I Love It: In two words: Rugged Reliability. This sight has withstood all kinds of abuse and still performs like a champ. What’s not to love?

Performance and Battery Life: I’ve got to say the Holosun HS507C X2 doesn’t compromise on performance. It features a 2 MOA red dot reticle, which is excellent for quick target acquisition. 

But wait, there’s more! It offers multiple reticle options, including a 2 MOA dot plus a 32 MOA circle. This gives you some flexibility in how you want to take your shots, making it a versatile choice for various shooting activities.

Why I Love It: The main draw for me? Value for money. It delivers most of what you’d get with more expensive sights but at a fraction of the cost.

My Experience

After going head-to-head, comparing the Holosun and the Trijicon SRO, I can confidently say the HS507C X2 makes for an excellent budget alternative. 

Performance-wise, it stood its ground. The 2 MOA red dot was crisp, and the additional reticle options were a pleasant surprise. 

Mounted on my Glock 45 MOS, it felt like a natural fit, and I found no significant drop-off in accuracy or reliability.


  • More budget-friendly than the Trijicon SRO

A lightweight, durable red dot sight that combines cutting-edge Motion Sensor Technology with top-tier durability.

Motion Sensor Technology: Alright, folks, let’s talk tech for a moment. The Motion Sensor Technology on this sight is not just a gimmick. 

When you’re aiming down the sights and even slightly move, MST kicks in to ensure your red dot is as accurate as can be. This isn’t just some random feature thrown in to look good on paper; it genuinely impacts your shooting performance. 

It knows when you’re in motion and adjusts, making sure your shot lands where you want it to.

Auto-Dimming Function: Coupled with MST, the sight has an auto-dimming function. Imagine you’re going from a sunny outdoor range straight into a dimly lit indoor one. 

Your sight adjusts the brightness on the fly. No fiddling with settings or squinting at an overly bright dot. This function takes environmental changes into account so you can focus more on the shot itself.

Durability and Construction: Now, let’s talk about build quality. Made from aircraft-grade aluminum, this sight has been tested to withstand up to 10,000 rounds. 

Ten thousand! Whether it’s daily use or extreme conditions, the DeltaPoint Pro holds up. It’s rugged but doesn’t feel like a brick, which is pretty much what everyone wants in a sight.

Waterproofing: Waterproof up to 33 feet. Yes, you read that right. Whether you’re caught in a downpour or accidentally drop it in a stream, this sight’s got your back. You won’t have to hold your breath worrying about water damage while you fish it out.

Why I Love It: The tech features, especially the MST and the auto-dimming function, are where the DeltaPoint Pro shines brightest for me.

It’s a sight that takes variables into account and adapts, providing a personalized shooting experience.

My Experience

  • The Venom Red Dot will fit well on your rifle or...

A sophisticated, compact red dot sight that offers unparalleled durability, crystal-clear vision, and user-friendly customizability.

Durability and Reliability: Talk about bulletproof! Constructed from 6061-T6 Aluminum, which is also featured in a number of Holosun optics, the Vortex Venom’s chassis promises an enviable shelf-life. This isn’t your run-of-the-mill aluminum. 

It’s highly resistant to rust, thereby increasing the sight’s overall longevity. Furthermore, the Vortex Venom is engineered to be both shockproof and water-resistant. So, whether you’re caught in a torrential downpour or accidentally drop it, this sight’s performance remains uncompromised. 

Size and Weight: Here’s something you’ll love. The compact size and feathery weight make it exceptionally portable and incredibly straightforward to mount. 

It’s as if the Vortex Venom was designed with the ease of the shooter in mind. The compact nature doesn’t just make it easy to carry; it also offers flexibility in terms of mounting options.

Glass Clarity: Glass clarity is where the Vortex Venom really shines. The sight features a wide field of vision, giving you a full view of the area surrounding your target. 

This isn’t just any glass; it’s fully coated with multi-layered anti-reflective material to enhance light transmittance and clarity. 

Vortex Optics even throws in an “Armor Tek” lens wrap that protects the glass from potential scratches, dust, and all sorts of environmental hazards.

Reticle: The Vortex Venom comes in two flavors: a 3 MOA and a 6 MOA reticle. While the 3 MOA reticle is specifically designed for pinpoint accuracy, the 6 MOA variant excels in both quick target acquisition and reasonable accuracy. 

The 6 MOA dot naturally appears larger to the eye, making it faster to spot, especially in fast-paced scenarios. Depending on your needs and the type of weapon you have, this customization is a massive win.

Eye Relief: The unlimited eye relief on this sight is an absolute game-changer. In my numerous field tests, target acquisition was a breeze. 

I could easily lock onto targets without the strain or discomfort one might experience with less forgiving optics. It just makes shooting that much more enjoyable.

Brightness Adjustment: Offering ten different brightness settings, the Vortex Venom is nothing if not adaptable. It provides two adjustment modes: automatic and manual. 

While automatic mode self-adjusts according to the ambient light conditions, manual mode lets you fine-tune the brightness to your specific needs. 

Why I Love It: The Vortex Venom is the embodiment of precision, durability, and flexibility. Its crystal-clear glass, durable construction, and user-friendly adjustments make it a top pick in my book.

My Experience 

From the first mount to the hundredth shot, the Vortex Venom has performed beyond my expectations. It has seamlessly integrated itself into my shooting setup, enhancing both my accuracy and overall shooting experience.


  • High-grade 6061-T6 Aluminum construction
  • Exceptionally lightweight yet robust
  • Crystal-clear glass with anti-reflective coatings
  • Choice of reticle for varying shooting styles
  • Incredible battery life with flexible brightness adjustments
  • Reliable windage and elevation adjustments


  • The battery compartment is somewhat restrictive.

6. Burris Fastfire – Most Affordable Option

  • Picatinny mount included
  • Windage and elevation adjustments that don't require a...
  • Three levels of brightness
  • 3 MOA Dot Reticle
  • Tool-less wind age and elevation adjustments

An affordable, efficient, and compact red dot sight optimized for rapid target acquisition on Glock 45 MOS.

Durability: You know how critical durability is, especially when we’re talking about red dot sights. Well, the Burris FastFire has you covered. 

Made from high-grade aluminum, it brings to the table a robust build that’ll withstand not just your average wear and tear but also the tough challenges of outdoor shooting and hunting. This isn’t just your regular aluminum, folks. 

Weather Resistance: The waterproof coating on this sight isn’t just a bonus; it’s practically a necessity for anyone who wants to take their shooting outdoors in all conditions. You’ll find this sight maintaining its performance, even if you’re stuck in a downpour. 

The coating ensures that neither fog nor rainwater seeps into the device, affecting your visibility or the electronics. In my testing, I put it through its paces in all sorts of conditions. Trust me, it didn’t falter.

Reticle Quality: The 8 MOA red dot reticle is your ticket to quick and efficient target acquisition. The red dot is sufficiently large for easy spotting but not too overpowering to cover your target. 

I found it especially useful during rapid-fire situations where milliseconds count. Larger dots naturally catch the eye quicker, which is what you get with an 8 MOA.

Battery Life: Battery life is often an overlooked feature, but not here. The Burris FastFire offers an impressive battery lifespan that can stretch up to 5 years, depending on your usage. 

The extended life comes from efficient electronics and a low-consumption LED for the red dot. That means you can head to the range or the great outdoors without the nagging worry of your sight dying on you. I’ve gone through several extended shooting sessions, and the battery indicator barely moved.

Why I Love It: What’s not to love? It’s durable, efficient, and doesn’t break the bank. The Burris FastFire is a well-rounded package, delivering performance usually reserved for pricier models.

My Experience

After months of use, the Burris FastFire has become a staple in my shooting gear. It’s reliable in all sorts of conditions, from rainy days to dusty trails. 


  • Aerospace-grade aluminum for optimal durability
  • Efficient waterproof coating
  • Quick target acquisition with 8 MOA red dot

A high-performance, low-mount red dot sight optimized for quick target acquisition and co-witnessing on Glock 45 MOS.

Low Mounting: Okay, let’s dive into the low mounting. This feature on the Viper aligns the red dot almost flawlessly with the firearm’s barrel.

You can also co-witness with your iron sights, thanks to this low-mounting setup. During my field testing, this really stood out. The low profile helped me maintain a consistent cheek weld, and the sight picture didn’t even blink when switching to iron sights for those farther-off targets.

6 MOA Bright and Sharp Red Dot: We’re talking about a 6 MOA red dot that’s incredibly bright and crisp. This size is particularly beneficial for rapid target acquisition, especially in close-quarters scenarios. 

My time with it validated the spec sheet. Whether I was in a dim indoor range or under the blazing sun, the dot remained bright and clear. 

Multi-Coated Lens and Armortek Coating: This sight isn’t just about its red dot. The lens on the Viper is fully multi-coated, providing a vivid, unobstructed field of view. 

Add the Armortek coating into the mix, and you get a lens that resists everything from dirt to oils and even minor abrasions. 

Why I Love It: What’s not to adore? The Viper offers top-notch performance with thoughtful features that genuinely enhance the shooting experience. The low mounting, in particular, is a game-changer for me.

My Experience

The Viper has been a steadfast companion on my Glock 45 MOS. From its low mounting profile to its excellent optical features and durable build, it’s proven its worth in each and every session. It’s easy to set up, easier to use, and easiest to fall in love with.


  • Low mounting allows for accurate shooting and co-witnessing
  • Bright 6 MOA red dot adaptable to various lighting conditions
  • A multi-coated lens with Armortek coating for durable, clear-sight picture
  • Robust, hard-anodized finish
  • Waterproof and shockproof


  • Battery life might not impress everyone

Final Verdict

Whether you’re looking for rugged reliability, affordability, or user-friendly customizability, there’s something here for every Glock 45 MOS owner.
