The Trijicon RMR Type 2 Adjustable LED sight offers a robust, long-lasting, and highly customizable red dot experience for your Ruger 57.

Easy-to-Use Buttons: One of the first things you’ll notice are the buttons on the sides of the optic. They’re a game-changer! You can adjust the brightness, toggle between manual and automatic modes, and even power it down when you’re not using it.

So, if you’re on a mission or at the range, you can quickly adapt to your environment. If you prefer manual control, you’ve got it for 16.5 hours after your last button press. Then, it reverts back to automatic mode to be ready for your next outing. It’s like the sight has its own internal clock!

Night Vision Compatibility: Yep, it’s night vision compatible. All of the RMR Type 2 Adjustable LED sights work seamlessly with night vision devices. 

Especially if you go with the 3.25 MOA dot size, you’re looking at optimal visibility. It’s excellent for those of us who like shooting at different times of day or in varied lighting conditions. 

Durability: Talk about rugged! The lens frame is duty-grade and designed to handle recoil like a champ. It can endure pressing against hard surfaces, and let’s not forget about its drop durability. 

The forged 7075 T6 aluminum frame is built to divert point impact stress away from the glass. Simply put, this sight is a tank.

Battery Life: Battery life? Oh, it’s insane! It rivals that of other sights like the SRO and Holosun 507C. You’re looking at a 3 to 4-year lifespan on the battery, which is super convenient. 

Lockout Feature: Sometimes, we accidentally press buttons; it happens to the best of us. The RMR offers a lockout feature, which disables the buttons and keeps the sight in automatic mode. 

This is excellent because it means no unintentional disruptions to your aiming solution. It’s like having a safeguard for your aim.

Dot Size: The 3.25 MOA dot size is by far the most popular, and for good reason. It’s small enough for precise aiming but also big enough to catch quickly. 

The dot size is like the Goldilocks of red dot sights, not too big and not too small, just right for most shooters.

Why I Love It: What’s not to love? The sight is versatile, durable, and dependable.

My Experience 

The sight integrates flawlessly with my Ruger 57, enhancing my accuracy and overall shooting experience. I’ve used it in multiple settings, from the range to tactical scenarios, and it’s never let me down.

The Vortex Venom Red Dot with a 3 MOA Dot offers rapid target acquisition and a lightweight build that is perfect for your Ruger 57.

3 MOA Dot Reticle: Let’s kick things off with that 3 MOA dot. It’s just the right size for quick target acquisition but still precise enough for those tighter shots. 

The daylight-bright red dot is a boon in any lighting condition. Whether you’re at an indoor range or outdoors under the blazing sun, this dot won’t let you down. 

Windage and Elevation Adjustment: Elevation and windage adjustments are super sleek on the Vortex Venom. Each click moves the point of impact by 1 MOA, and it’s as straightforward as following the arrows on the dials. 

There is no need for any tools or fumbling around. In terms of application, you’ll find the adjustments quite handy whether you’re dialing in at a range or adjusting for wind during an outdoor session. It’s all a piece of cake!

Battery Life and Power Controls: Powering this bad boy is a CR 1632 battery. While the battery life may not be its strongest suit, the convenience is next-level. 

Battery swaps? Right from the top, so there is no need to remove or re-zero the sight. And the controls for dot intensity and power are right on the side.

Wide Field of View: The field of view is broad, giving you an expansive look at your target area. The lens is fully multi-coated, offering a clean and bright visual experience. 

Top-Loading Battery Access: Remember what I said about battery swaps? The top-loading design is a game-changer. There is no need to remove the sight or mess up your zero. 

Just pop the top, switch the battery, and you’re good to go. In terms of application, this means less downtime and more shooting time.

Build and Durability: Machined aluminum housing ensures this sight can take a beating. While it might not be duty-grade, it’s still rugged enough for range use. Whether you’re in a tactical training session or a day at the range, this sight holds its own.

Why I Love It: It’s all about that fast target acquisition and user-friendly design for me. It’s as if the sight is asking, “How can I make your shooting experience better?” And boy, does it deliver!

My Experience 

I’ve put this sight through the wringer on my Ruger 57, and it’s been a blast. From quick target acquisition to the ease of adjustments, it adds a layer of efficiency and fun to my shooting sessions.


  • Rapid target acquisition
  • Wide field of view
  • Top-loading battery access
  • Lightweight and small profile
  • Affordable

  • Not duty grade

3. Holosun 507C X2 – Best Budget Alternative of the RMR

The 507C sight delivers rapid dot recentering, is built like a tank, and is designed for optimal performance on a Ruger 57.

Reticle: The reticle is something to write home about. This sight features an outer 250 MOA ring designed to help you quickly recenter the reticle after each follow-up shot. This is extremely useful for fast-paced shooting scenarios. 

The ring essentially guides your eye back to the center, ensuring faster target reacquisition. For those who might find the ring distracting, don’t worry; you can easily turn it on and off as you see fit.

Easier Slide Racking: Now, let’s talk about slide racking. We all know that the Ruger 57’s slide can be a bit small, especially for shooters with larger hands. 

The 507C’s design offers an added advantage here. Its larger surface area makes gripping the slide to rack it way more comfortable and efficient. It’s a simple but impactful feature that noticeably improves the overall shooting experience.

Easier Battery Access: Battery replacement is often a cumbersome task, but not with the 507C. You can swap out the battery from a side tray without having to remove the sight or re-zero it. 

This feature ensures that you spend more time shooting and less time fiddling around with equipment. It’s a well-thought-out feature that adds to the sight’s overall usability.

Super Lightweight: The weight, or lack thereof, is remarkable. When mounted, the sight’s weight is so minimal that you hardly notice it’s there.

Plus, it doesn’t interfere with the slide cycling performance, which is great. For those who are concerned about adding extra weight to their firearm, this sight is a dream come true.

Built Like a Tank: Made with 7075 T6 aluminum, this sight is designed to endure. It can withstand rough use in the field and matches the durability of mil-spec Trijicon RMR models. If you’re the type who isn’t gentle with your equipment, rest assured, this sight can take it.

Optical Clarity: While generally clear, the sight can occasionally deliver blurry vision. This is something to be mindful of, especially in high-stress situations where optical clarity is crucial. It’s not a deal-breaker, but could use some improvement.

Why I Love It: The  Reticle and the ease of battery replacement are game-changers for me. These features make the sight incredibly user-friendly and efficient.

My Experience 

I’ve field-tested this sight extensively on my Ruger 57. It excels in rapid target reacquisition, thanks to the  Reticle. Battery replacement and slide racking are a cinch, making it an excellent addition to my shooting toolkit.

  • Tool-less wind age and elevation adjustments
  • Low Battery warning indicator
  • 8 MOA Dot Reticle
  • Tool-less wind age and elevation adjustments

The Burris FastFire 3 is a lightweight, durable, and versatile micro red dot sight with multiple dot size options.

Auto Brightness Control: Now, let’s dive into the auto brightness control, shall we? When you’re out on the field, the last thing you want to do is fumble around with settings. 

With the Burris FastFire 3, you get a sight that automatically adjusts its brightness to the surrounding light conditions. This ensures that your reticle is always bright enough to see but not so bright that it’s blinding.

The automatic adjustment is seamless, helping you maintain focus on your target rather than messing around with buttons.

Durability and Affordability: In terms of durability and affordability, the FastFire 3 really shines. With a battery life extending up to 5 years, you can rely on this sight for the long haul. 

Constructed from high-quality materials, the sight can withstand the usual wear and tear, all without burning a hole in your pocket. In an industry where quality often comes at a steep price, it’s refreshing to find an optic that offers both durability and affordability.

Ultra-Lightweight Design: Have you ever added a new accessory to your firearm only to find that it throws off your aim? The Burris FastFire 3 avoids that problem entirely. Its ultra-lightweight design ensures that you can easily guide your muzzle to your target. 

It’s so light that you almost forget it’s even there. This is a huge plus for those long days in the field when even a small amount of extra weight can start to feel like a burden.

Dot Size Selection: Variety is the spice of life, and that’s certainly true when it comes to dot sizes. Whether you have perfect vision or deal with astigmatism, there’s a dot size that will suit your needs. 

From 3 MOA to 8 MOA and beyond, the options available allow you to customize your shooting experience. The freedom to choose your dot size enhances your accuracy, particularly when you need to take shots at varying distances.

Top-of-Sight Battery Access: Nobody wants to disassemble their entire setup just to replace a battery. With top-of-sight battery access, swapping out batteries becomes a straightforward task. This design decision keeps you in the field longer, saving you both time and frustration.

Why I Love It: What’s not to love? The Burris FastFire 3 provides a fantastic combination of affordability, durability, and customization. It’s an all-around winner in my book.

My Experience 

Mounted on my Ruger 57, the FastFire 3 performed exceptionally well. From target acquisition to maintaining a consistent aim, it excelled in all aspects. I was particularly impressed by the auto-brightness control, which adapted flawlessly to various lighting conditions.

The Trijicon SRO is a high-quality optic that offers a large field of view and easy top battery access, making it a dream for any Ruger 57 owner.

Very Large Field of View (FOV): Okay, where do I even start with this feature? The large field of view is honestly a game-changer. When I first mounted the Trijicon SRO onto my Ruger 57, I was blown away by the sheer amount of visibility I had. 

The circle-shaped window is exceptionally large, allowing for quicker and more effective target acquisition. This is especially useful when you’re in a dynamic shooting environment where time and precision are of the essence. 

Top Battery Access: Now, let’s talk battery access. Much like the Holosun 507C, the Trijicon SRO offers top battery access. This is crucial for me because the last thing I want is to remove my sight just to change a battery. 

With top battery access, you can simply swap out the battery while keeping your sight perfectly zeroed. For someone who values their time on the range, this feature is an absolute must-have.

Brightness Lock Mode: Trijicon didn’t skimp on features here. The brightness lock mode is a little thing that makes a big difference. 

You can lock in your desired brightness setting so it doesn’t accidentally get toggled while you’re shooting. In a high-stakes situation or even during an intense practice session, you don’t want to be distracted by an overly bright or dim reticle.

Clear and Crisp Dot: The 2.5 MOA Red Dot is as clear as day. Coupled with an exceptionally transparent front lens, your sight picture couldn’t be better. 

This clarity makes a noticeable difference when you’re shooting at various distances or under different lighting conditions.

Easy and Adjustable Windage & Elevation: Zeroing can often be a real pain, but with the SRO, it’s a walk in the park. 

The tool-less design allows for hassle-free adjustments to both windage and elevation. No more fiddling around with tiny screws or needing special tools. This keeps you shooting, not tinkering.

Why I Love It: The large FOV, easy battery access, and superior clarity make the SRO an unparalleled joy to use.

My Experience

Shooting with the SRO mounted on my Ruger 57 felt like a whole new experience. The target acquisition was fast, and the sight adjustments were effortless. I particularly enjoyed the large field of view, which made tracking and hitting targets a breeze.


  • Massive field of view
  • Easy top battery access
  • Same footprint as RMR for easy installation
  • Brightness lock mode
  • Crystal-clear 2.5 MOA Red Dot


  • Lens frame not built to duty grade

The DPP is a rugged, waterproof sight with a large window for an expansive field of view, perfect for dynamic shooting with your Ruger 57.

Huge Sight Window: So, first off, let’s talk about the sight window. Like the Trijicon SRO, the Delta Point Pro also offers a massive sight window, which is fantastic for fast target acquisition. 

The larger your field of view, the easier it is to keep your eyes on the target. Especially when you’re switching between multiple targets, this feature can make or break your shooting experience. 

That’s why I’m totally digging the sight window on the Delta Point Pro; it elevates the shooting game to the next level.

Waterproofing: Another feature that caught my eye, literally, was the waterproofing. The Delta Point Pro is waterproof up to 33 feet, which gives you a layer of assurance if you’re shooting in different weather conditions. 

Let’s be real; the weather doesn’t always cooperate, and the last thing you want is a sight that fogs up or gives out when you’re mid-action.

Battery Life and Easy Changes: The battery life on the Delta Point Pro clocks in at 300 hours. While this isn’t as impressive as some of the other sights out there, what it lacks in battery life, it makes up for in convenience. The spring-actuated battery compartment is located on top, meaning you don’t have to remove the sight for battery changes. Trust me; it saves a lot of hassle.

Why I Love It: I have to say, the Delta Point Pro scores high with its field of view and waterproofing. These features alone make it a contender in my books.

My Experience 

When I mounted the Delta Point Pro on my Ruger 57, the first thing I noticed was the sight window. It really is something else. 

Target acquisition became faster and felt more natural. The waterproof feature came in handy during an unexpected downpour, and the sight didn’t let me down. However, I did notice the added weight after a while, but it wasn’t a major issue for me.


  • Large sight window enhances target acquisition
  • Waterproof up to 33 feet
  • Convenient spring-actuated battery compartment
  • Easy top battery access


  • Slightly on the heavier side

7. SIG Romeo 3XL – Best for Tactical Hunting

The ROMEO3XL offers a classic 3-MOA red-dot reticle, MOTAC technology, and weather-resistant construction, all wrapped up in lightweight aluminum housing.

Durable, Lightweight Construction: First things first, the construction of this sight is quite impressive. It’s made of aircraft-grade CNC Aluminum. 

This means it’s not just durable but also lightweight. When you’re out in the field, every ounce counts. You want something reliable that won’t weigh down your gun, and the ROMEO3XL nails this balance beautifully.

3 MOA Red-Dot with 12 Illumination Settings: The ROMEO3XL sports a classic 3-MOA red-dot reticle that most shooters will find familiar and easy to use. What makes it even better are the 12 illumination settings: 10 for daylight and 2 for night vision. 

This is incredibly handy because, let’s be honest, not all shooting happens under perfect lighting conditions. Whether you’re at the range during high noon or out in the field at dusk, this sight has got you covered.

Weather Resistant: Let’s talk about its weather resistance. With IPX-7 waterproof and fogproof construction, the ROMEO3XL isn’t afraid of a little bad weather. 

The last thing anyone wants is for their sight to fog up or malfunction in the rain, and thankfully, this sight takes those worries off the table.

Why I Love It: For me, the winning feature is the MOTAC technology. The ability for the sight to sense movement and conserve battery life is a game-changer.

My Experience

Mounting the ROMEO3XL on my Ruger 57 was easy. The 3-MOA red dot made target acquisition straightforward, and the MOTAC tech was super convenient. 


  • Lightweight but durable construction
  • Classic 3-MOA red-dot with multiple illumination settings
  • MOTAC technology for extended battery life
  • IPX-7 weather-resistant features


  • Not as durable as some competitors

Final Verdict

After putting each of these red dot sights through their paces on my Ruger 57, the verdict is in. While each sight has its own unique benefits and drawbacks, my top choice has to be the Trijicon RMR Type 2 Adjustable LED sight. 

But remember, the best sight for you will ultimately depend on your individual needs and preferences. Whether you prioritize durability, battery life, or versatility, there’s a sight on this list that’s perfect for you.
