The Trijicon RMR Type 2 is a robust and highly reliable red dot sight, designed to perfectly complement your SIG P226.

Multi MOA Dot Size Options: Let’s talk about the options for MOA (Minutes of Angle) dot sizes that this sight offers. When I was using it, the 6.5 MOA dot seemed like a match made in heaven for the P226. 

Here’s why it’s a real benefit. If you have astigmatism, the multiple MOA options can be a lifesaver. You can easily switch between dot sizes to find one that minimizes distortion, allowing for quicker and more accurate target acquisition. 

Improved G Force Handling Performance: Okay, so if you’ve been using red dot sights, you know how jarring it can be when the dot just vanishes because of high G forces, especially during rapid movements or recoil. 

That’s where this feature comes in. The RMR Type 2 has been engineered to ensure that the CR2032 battery is gripped securely. 

Slide Racking Assist: This might sound trivial, but hear me out. The sturdy build of this sight assists with slide racking. 

How does this work? The sight’s design allows you to rack the slide against hard surfaces without damaging the sight or, more importantly, its functionality.

Battery Conservation Mode: This sight has a battery conservation mode that automatically adjusts the aiming dot’s brightness based on ambient lighting conditions. 

The point here is efficiency and long-lasting use. When it’s bright out, the dot brightens up, but when you’re in dimmer conditions, it dials down. You won’t find yourself caught with a dead battery when you least expect it.

Why I Love It: Honestly, what’s not to love? The Trijicon RMR Type 2 packs a whole lot of features into a small package. It’s durable, versatile with its MOA dot size options, and incredibly reliable. 

My Experience

I’ve had an absolutely stellar experience using the Trijicon RMR Type 2 on my SIG P226. It’s been a reliable companion, whether I was at the shooting range or navigating through uneven terrains for a more dynamic shooting experience.


  • Durable and robust design
  • Multiple MOA dot size options
  • Excellent battery management
  • Sturdy housing enhances durability
  • Slide racking assist is functional and practical


  • Higher price may not fit all budgets

The Trijicon SRO is a top-tier red dot sight designed for speed and accuracy, offering an expansive field of view on your SIG P226.

Rugged Construction: Now, let’s kick things off with its durability. We’re talking 7075 T6 Aluminum here. This isn’t your everyday aluminum; it’s a type commonly used in aerospace. The housing on this baby is virtually indestructible.

I mean, this thing resists damage like a champ. It even comes with scratch-resistant lens frames, which is a nice bonus.

Large Field of View: Okay, the field of view on this thing is a game-changer. Unlike most red dot sights, the SRO gives you an incredibly large, unobstructed field of view. 

This feature is super handy when you’re trying to keep an eye on a moving target as well as its surroundings. I’ve found this incredibly useful in various scenarios, from shooting ranges to tactical drills. 

Clear, Crisp Red Dot: No red dot sight is worth its salt without, well, a clear red dot. The SRO offers three reticle variations: 1 MOA, 2.5 MOA, and 5 MOA.

I’ve mostly stuck to the 2.5 MOA option for my SIG P226. Each reticle provides a bright, sharp, and accurate dot that enables you to hit your target with greater precision. 

Top-Loading Battery: Nobody wants to fumble with battery replacements, especially when you have to remove your sight to do so. The SRO smartly sidesteps this issue by incorporating a top-loading battery compartment. 

This means a faster, hassle-free battery change that keeps the sight on your firearm. You’re back in action in no time without having to re-zero your sight. Convenient, right?

Adjustable Illumination Controls: Lighting can be tricky, and the SRO gets that. That’s why it comes with up to eight levels of adjustable illumination. 

Whether it’s blazing sunlight or low-light conditions, this sight has got you covered. The controls are super easy to use, allowing you to quickly toggle through brightness settings until you find the one that’s just right for your environment.

Why I Love It: The Trijicon SRO brings a host of features that have noticeably improved my shooting game. The expansive field of view keeps me aware of my surroundings, while the crisp red dot ensures pinpoint accuracy. 

The top-loading battery feature is a time-saver, and the adjustable brightness settings adapt to any light condition. Overall, it’s a fully loaded package of durability and functionality that has elevated my SIG P226 experience.

My Experience

I can say, without a doubt, that my experience with the Trijicon SRO has been fantastic. Its features, from the robust build to the wide field of view, have significantly upped my accuracy and reaction time, even under less-than-ideal conditions.


  • Unbeatable durability with 7075 T6 Aluminum housing
  • Expansive field of view
  • Multiple reticle options for tailored shooting
  • Convenient top-loading battery design
  • Versatile brightness settings


  • A bit on the pricey side, making it a stretch for some budgets

The HOLOSUN HS507C X2 is a feature-rich, durable open reflex pistol sight with near-infinite battery life, perfect for the SIG P226.

Battery Life: Okay, now let’s talk about battery life. Promising a whopping 50,000 hours, the HS507C X2 is basically the Energizer Bunny of red dot sights. Long shooting sessions? Weekend trips? This sight has got you covered. 

But here’s the kicker: it also has an integrated solar panel that serves as a fail-safe power backup. The longevity and power efficiency are unrivaled.

Side-Loading Battery: Here’s a feature I didn’t know I needed until I had it: the side-loading battery compartment. It’s not just a tiny detail; it’s a game-changer. 

Gone are the days when you had to remove the sight just to change the battery, messing up your zero in the process. 

Solar Power Backup: Another thing to love about this sight is the solar fail-safe backup feature. Should your battery ever run out, this feature jumps in to save the day. 

The sight stays powered and ready for action, keeping you worry-free. It’s like having a safety net; you know you’re always covered, and that adds a layer of reliability that you can’t put a price on.

Durability: Crafted from 7075 aluminum housing, this sight screams durability. It’s built like a tank but without the weight. It’s shock-resistant, which is critical if you’re using it for tactical purposes or rugged outdoor activities. 

The glass lens comes multi-coated and the sight is waterproof up to 1 meter. Put simply, the holosun 507c can take a beating and keep on ticking.

Why I Love It: The HOLOSUN HS507C X2 has won me over with its incredible features and durability. The near-infinite battery life, along with the solar backup, gives me peace of mind during extended use.

My Experience

I’ve been using the HS507C X2 and it’s been an absolute workhorse. Whether it’s been rain or shine, this sight has never let me down. I’ve put it through its paces, and it’s passed with flying colors.


  • Exceptional battery life with solar backup

  • Robust and durable 7075 aluminum construction
  • Clear, multi-coated glass lens

  • The Venom Red Dot will fit well on multiple...

The Vortex Venom offers top-tier performance in a compact, lightweight design, without draining your wallet.

Durability and Reliability: What sets this sight apart right from the get-go is its construction. Manufactured with 6061-T6 Aluminum, the Venom is shockproof and water-resistant. No need to worry about a little rain or even a tumble; it’s got your back.

When you’re out in the field, whether it’s a dusty day at the range or a drizzly afternoon in the woods, this sight holds up well. 

Glass Clarity: The quality of the glass on the Venom is just fantastic. It features a multi-layered anti-reflective sealant that improves light transmission and offers clear, bright images. 

Added to this is the Armor Tek wrap, which does a bang-up job protecting against scratches and grime. 

Reticle Options: This sight provides two reticle options: 3 MOA and 6 MOA. That kind of flexibility is awesome because it allows you to adapt based on what you’re shooting. If you need quicker target acquisition, the 6 MOA works like a charm. 

On the flip side, for precision shots, especially at a distance, the 3 MOA gives you that finer point of focus. So, based on your shooting needs, you can toggle between these options for the best possible results.

Why I Love It: What’s not to love about the Vortex Optics Venom? It strikes the perfect balance between performance and affordability. 

The sight’s robust build ensures longevity, while its clear glass and versatile reticle options offer top-notch accuracy. Its lightweight design and long battery life make it convenient and reliable. Simply put, it has upgraded my shooting experience in every way possible.

My Experience 

I’ve been nothing short of impressed with the Venom. Its durability has proven itself in various weather conditions. The sight’s compact design blends seamlessly with my SIG P226, and the glass quality offers vivid clarity in any light. 

The 3 MOA and 6 MOA reticle options have allowed me to be more versatile in my shooting.


  • Robust, weather-resistant design
  • Extremely lightweight and compact
  • Crystal-clear glass quality
  • Two reticle options for adaptability
  • Long-lasting battery life

  • Motac (Motion Activated Illumination System)...

The Sig Romeo 1 Pro is a high-end 1X30mm pistol red dot sight, designed to provide rapid and precise target acquisition on your Sig P226.

TruHold Design: When you talk about reliability in a red dot sight, the TruHold Lockless Zeroing System comes to mind immediately. Sig Sauer really knocked it out of the park with this feature. It uses dual adjustment springs that make sure the sight can handle the 9mm recoil from your SIG P226 and still hold its zero.

Motion Sensor: The Romeo 1 Pro comes equipped with a smart motion sensor, which I consider an absolute win for battery conservation. The sight turns off when idle for an extended period and powers back up the moment it senses motion. 

With this feature, you’re looking at an impressive battery life of about 20,000 hours. The motion sensor is a thoughtful addition that effectively maximizes battery life without requiring any manual adjustments or turning it off and on continually. 

Material and Durability: Crafted from aircraft-grade CNC aluminum, this sight is built to last. It can withstand not just the daily wear and tear but also more severe conditions in the field. 

With an IPX 7 rating, it’s also waterproof. When you pair this durability with your SIG P226, you’ve got a combination that’s ready to face just about anything you throw at it. Whether it’s rain, dirt, or rough handling, this sight remains steadfast.

Brightness and Versatility: The brightness settings on the Romeo 1 Pro are versatile, featuring 12 settings (10 Daytime/2 NV). This range allows for rapid target engagement under various lighting conditions. 

The sight is also equipped with a point-source emitter for exceptional brightness. 

Why I Love It: What’s not to like about the Sig Romeo 1 Pro? It comes packed with features that are both practical and innovative. The TruHold system ensures that the sight holds its zero impeccably.

My Experience

Ever since mounting the Romeo 1 Pro on my SIG P226, it’s been nothing short of a revelation. Its top-notch features like the motion sensor for battery conservation and the TruHold system for zeroing, have made it incredibly reliable. Also, its lightweight design has made target acquisition swift and natural.


  • Exceptional zeroing capabilities with TruHold
  • Smart motion sensor for extended battery life
  • Sturdy, aircraft-grade CNC aluminum build
  • Lens offers high clarity and brightness
  • Remarkably lightweight and easy to use

The generous field of view lets you get on target swiftly while maintaining a keen awareness of your surroundings. It’s the kind of feature you won’t want to live without once you’ve experienced it.

Durable Construction: Constructed from 7075 T6 Aluminum, this red dot sight is like a little tank. Believe me, this thing can take a beating! It’s water-resistant, fog-resistant, and shock-resistant. 

You’re getting industrial-grade toughness built to withstand real-world conditions. It’s not just an accessory; it’s a piece of equipment you can rely on when the going gets tough.

Why I Love It: What’s not to love about the Leupold DeltaPoint Pro? It brings together ruggedness, crystal-clear visuals, and tech-savvy features. 

The expansive field of view, combined with the diverse reticle options, means that target acquisition has never been easier.

My Experience

I’ve tested this sight extensively on my SIG P226, and boy, it delivers! The motion sensor tech 

works like a charm, the reticle stays clear and bright, and the sight holds zero perfectly, even after battery swaps.


  • Incredibly durable and weather-resistant
  • Battery compartment design makes for quick changes
  • Motion Sensor Technology keeps the sight always ready
  • Maintains zero perfectly


  • It is a bit on the heavier side compared to other micro-red dots

Final Verdict

So, here we are at the finish line. I’ve been hands-on with these red dots, putting them through their paces on the SIG P226. Each sight brings something different to the table, be it a wide viewing window, user-friendliness, or durability. 

But when the dust settles, my top pick has got to be the Trijicon RMR Type 2. Now, your perfect fit might differ based on your unique needs and preferences, and that’s okay! This article aims to equip you with the details you need to make that choice for yourself.


What red dots fit on a SIG P226?

The red dots, Trijicon RMR, SRO, Holosun 507C X2, Vortex Venom, SIG Romeo 1 Pro, and Leupold Deltapoint Pro, are all compatible with SIG P226.

Can you put an optic on a SIG P226?

Yes, you can mount an optic on a SIG P226, either via a mounting plate or an adapter for the existing rail.

What is the effective range of a Sig Sauer P226?

The effective range of the Sig Sauer P226 is approximately 50 meters.

Why did the SEALs drop the Sig P226?

The SEALs transitioned to the Glock G19 because it’s 7 ounces lighter than the Sig P226, offering easier maneuverability and less weight in gear.

Which is better, Glock 19 or Sig P226?

The Glock 19 is more versatile for concealed carry, while the Sig P226 excels in other aspects but is heavier. Your choice depends on your specific needs.

Is the P226 better than the P320?

The P226 and P320 are both reliable; the P226 is “better” if you prefer a DA/SA system, while the P320 is better if you don’t. The P226 is also more expensive.
