Best RMR Sight for Handguns

Whether you're a veteran shooter or a newcomer to the world of handguns, the concept of a pistol sight probably isn't foreign to you. More than just a fad, RMR sights have been steadily climbing the ranks of must-have pistol accessories.

Over the years, these compact but capable sights have proved their mettle time and again, offering quick target acquisition and improved accuracy. But with an ocean of options out there, finding the right fit for your firearm can feel overwhelming.

That's where we come in. In this guide, we'll take you through the ins and outs of the best RMR sights for handguns. Let’s get you ready to make an informed decision and amp up your shooting game.

What is an RMR Sight?

An RMR sight, you ask? These optics go by a few names. Trijicon's RMR stands for Rugged Miniature Reflex. You'll often hear these terms in general as well: Red Dot Optics (RDOs), Micro Red Dots (MROs), or simply Red Dot Sights (RDS).

It might seem a bit overwhelming but don't fret — these names all boil down to essentially the same thing. For consistency, we'll stick to calling them RMRs throughout this article.

An RMR is a compact optic, composed of a sturdy metal or plastic frame that houses a piece of glass. The magic happens when a red dot is projected onto that glass.

The process for the shooter becomes refreshingly simple: Look at your target. Place the dot where you want your shot to land. Pull the trigger.

Pros & Cons of RMR Optics

In case you're wondering what the difference of a Trijicon SRO vs RMR... all you need to really know is that SRO's are typically used by competition shooters and that they can be quite fragile. Whereas the RMR is well known to essentially be an indestructible tank. We go into the details below:

Pros

• Simplified Targeting: Increases target acquisition speed.
• Improved Accuracy: RMR sights greatly enhance accuracy at distances beyond 15 yards. The red dot provides a more precise aiming point than the top of an iron sight.
• Quick Shooting: In trained hands, RMR pistol sights can help increase your shooting speed.
• Buttons: If you opt for an adjustable model, you'll find that the +- buttons on the sides of the optic are quite tough and not that easy to actuate which is good because it means the brightness won't change without you intentionally doing so.

Cons

• Battery Location: RMRs have to be completely removed from the slide in order to replace the battery which means every time you install a new one you also have to rezero your optic which is a pain.
• Prone to Fogging: The optics could potentially fog when transitioning from cool indoor climates to hot, humid outdoor environments - but this is the same for any open emitter.
• Dust Accumulation: Dust or lint can easily gather on the lens (especially if you carry IWB) potentially reducing the light transmitted through it - or just requiring frequent cleaning.
• Learning Curve (Not really a con): Those transitioning from iron sights often struggle to locate the dot in the window initially. However, this is an obstacle that can be overcome with training and practice.

Factors to Consider When Choosing RMR Sights

When it comes to choosing the perfect RMR sight, several factors can impact your decision:

-Durability

-Reticle size

-Battery life

-Mounting compatibility

-Price tag

All these factors play significant roles. But one aspect that often confuses new buyers is the MOA dot size.

MOA Dot Size

MOA, or Minutes of Angle, is a unit of measurement that sight manufacturers use to define the size of the red dot. A common misconception is that a larger MOA dot means a less accurate sight. That's not exactly the case.

The size of the dot can significantly impact how you use your sight. Larger dots (like a 6.5 MOA) are quicker to acquire, making them ideal for close-quarter situations or competition where speed is of the essence. They're often favored by law enforcement or home defense users who value a fast response.

Smaller dots (like 1 MOA or 3.25 MOA) offer high precision at longer distances. They cover less of the target at range, allowing for more precise shots. A popular choice for target shooters or those who require precision over speed.

Keep in mind that neither side is inherently superior—it all comes down to your specific needs and shooting style or what you train to be good with.

Durability and Reliability

RMRs are extremely rugged and reliable (hence the name). They’re capable of withstanding the recoil and the inevitable knocks and bumps they'll encounter. Shooters can expect their RMR to have a consistent performance, holding zero and providing a clear sight picture in all conditions.

Reticle Type

While the term "red dot sight" is widely used, it doesn't fully cover the variety of reticle options available in RMR sights. Yes, the classic red dot is the most common and popular choice, but there's more out there to explore.

• Dot: This is the most common type of reticle and is what RMR's offer. The dot, typically red, serves as the aiming point. Sizes vary, but popular options include 1 MOA, 3.25 MOA, and 6.5 MOA. Each size has its strengths, as we've previously discussed.
• Crosshair: RMR's do not have this. Some pistol red dot sights offer a crosshair reticle, which might be preferred by those who transition from traditional rifle scopes. This is weird, we do not recommend.
• Circle Dot: RMR's do not have this. This reticle combines a center dot with a larger surrounding circle. This setup can be beneficial as the larger circle allows for faster target acquisition in close-range shooting, while the center dot facilitates precision at longer distances.
• Chevron: RMR's do not have this. A less common but unique reticle type, the chevron uses an inverted 'V' as the aiming point. The tip of the chevron offers a precise aiming point, while the wide base can help with quick target acquisition.

The color of the reticle also plays a role. Red is the most common, but other colors like green or amber are also available. Some people find these colors to be more visible against certain backgrounds or lighting conditions.

Choosing the right reticle type is largely a matter of personal preference and depends on your shooting style and requirements. Try out different options, if possible, before settling on your choice.

Battery Life

Optics manufacturers have been innovative in designing features to ensure your sight stays powered up for longer and minimizing the chances of your sight going dark when you need it most. Trijicon is no exception to that.

• Auto Shut-off and Wake-up: Some RMR sights come with an automatic shut-off feature that turns the sight off after a certain period of inactivity which significantly saves battery life. When it senses movement again the sight 'wakes up' and turns back on. This feature is known as "Shake Awake," and is a useful way to extend battery life without sacrificing readiness.
• Adjustable Brightness Settings: Many RMR sights allow the user to adjust the brightness of the red dot. This allows you to balance visibility with battery consumption. Using a lower brightness setting in low light conditions can help prolong the battery life.
• Solar Backup: Some models of RMR sights even incorporate solar cells to supplement battery power, further enhancing battery longevity. While not a replacement for battery power, this feature can give you that extra peace of mind.

Mounting Capability

Attaching an RMR-compatible sight to a pistol is not as simple as adding a Picatinny rail. The process is more complex compared to attaching a rifle red dot sight. Your pistol's slide needs to be specially cut to accommodate an RMR-type optic.

Several factory-made guns already have this feature such as the Glock MOS series, which has a portion of the slide milled out to accept the optic.

If you're aiming to mount a standard-format red dot, you'll need a mounting plate. This component attaches to your firearm and includes the correct screw patterns for your specific sight.

When mounting your RMR optic, you should thoroughly clean the mounting surface, be it a plate or directly on the slide. It's also crucial to use a thread locker, which keeps the screws from loosening over time and throwing off your zero.

It's equally important to tighten screws to their recommended torque spec. If the screws are too loose, they may allow the optic to shift, making a consistent zero quite challenging to maintain. Remember, correct mounting is essential for the best performance and reliability of your RMR sight.

Price Range

The cost of RMR sights varies significantly, with prices falling anywhere between $400 and $600. At the lower end, you'll find basic models that are great for beginners or those on a tight budget. These are typically less durable and may lack some advanced features but can provide good value for the money.

In the mid-range you'll find RMR sights that balance affordability with improved durability and features. They might not offer the longest battery life or absolute precision, but they will be reliable companions for most shooting activities.

At the high end you'll encounter sights like the Trijicon RMR Type 2. These RMR sights are the cream of the crop, delivering top-notch durability, superior performance, and premium features. They command a higher price, but their quality can be well worth the investment for dedicated and professional shooters.

The key is to choose an RMR sight that suits your specific needs and budget. Regardless of the price range, it's essential that the sight is compatible with your firearm and meets your shooting requirements. After all, an RMR sight is an investment in enhancing your accuracy and shooting experience.
