I’ll start by briefly describing the Holosun 507C and the Trijicon RMR and the companies behind them. 

The Holosun 507C, usually known as the Holosun HS 507C X2, is a popular open reflex micro red dot sight. This pistol optic is manufactured by Holosun Technologies Inc. a Chinese company that was founded in 2013. The company has gained recognition in the firearms industry for producing a range of affordable and high-quality optics.

Holosun is known for its red dot sights and reflex sights, which are designed for various applications, including handguns, rifles, shotguns, and other firearms. Their products often feature innovative technologies such as solar panels for extended battery life and Multi-Reticle System (MRS) options.

The Trijicon RMR, or Ruggedized Miniature Reflex, is another popular series of red dot sights manufactured by Trijicon, an American manufacturer of high-quality optics and aiming solutions. The Trijicon RMR is designed for rapid target acquisition and enhanced accuracy in various shooting applications including handguns, rifles, and shotguns. 

For this analysis, let’s start with the basics: the technical specifications of each model.  To test both red dot sights, I used my favorite firearm—my Smith & Wesson M&P semi-automatic.

Should you get a Holosun 507C? Or do you prefer a Trijicon RMR? I’ll help you decide by presenting several elements of both red dot sights. Let’s examine the optics’ performance, battery life span, robustness, trustworthiness, brightness adjustments, as well as the size and weight of these widely chosen red dot sights.

Optical Performance

The Holosun 507C stands out with its extraordinary lens clarity, devoid of the typical blue or green tint seen in many of its counterparts. The lens’s multi-coated glass also eliminated glare and unwanted reflection. 

The Trijicon RMR, on the contrary, has a faint blue tint due to its dichroic coating to emphasize the reticle. However, it’s so slight it’s hardly noticeable and doesn’t hinder performance.

Both are parallax-free, so the reticle stays on target even if my eye position shifts. Because both are open-reflex sights, I can keep my eyes open while keeping track of my target. This enables me to enjoy improved situational awareness.

Both have similar window sizes although the slightly more spherical shape of the Holosun 507C seemingly provides a more encompassing view.

Battery Life

The Holosun 507C has an incredibly impressive battery life, clocking in at a whopping 50,000 hours—that’s roughly five years of continuous use from just a single CR2032 battery. This is, in part, thanks to its Solar Fail-safe system that automatically adjusts the intensity of the reticle based on the ambient lighting conditions; the reticle doesn’t have to stay at full power. 

In addition, solar cells also provide power to the Holosun 507C, further conserving battery power. If I run out of batteries and I don’t have any spares, I’m assured that the red dot will still light up as long as there’s daylight. 

The Trijicon RMR holds its own with a commendable four years of continuous use from the same type of battery. Although this might seem less in comparison, it’s still a hefty amount of time in practical use.

It also incorporates a similar battery conservation technology as the Holosun 507C which automatically adjusts the aiming dot’s brightness to ambient lighting conditions. 


Both of these sights are designed to endure tough circumstances. The Holosun 507C is built from sturdy 7075 aluminum and can be submerged under 1 meter of water. It can easily resist most impacts, vibrations, and recoil shocks.

The Trijicon RMR, conversely, is made from military-grade forged aluminum and can resist water up to 20 meters. In addition, the patented shape of the housing deflects blows to prevent impacts from damaging the device. This is why the RMR is widely recognized for its durability in the industry and is often the preferred choice of law enforcement and military professionals.

The Trijicon RMR has ruggedized battery contacts and electronics that ensure optimal performance and survivability in harsh environments. In this aspect, the RMR is the clear winner.

Brightness Settings

Both the Holosun 507C and the Trijicon RMR excel in their ways.

 The Holosun 507C boasts 10 adjustable brightness settings, including two specifically tailored for night vision gear. This flexibility makes it a suitable companion for a diverse range of shooting environments.

The Trijicon RMR has fewer settings—8 to be exact, including one night vision-optimized setting. But for all intents and purposes, it doesn’t fall short in terms of its effectiveness. The precision in adjustments and the brightness of the RMR’s reticle are favorites among users.

Size and Weight

The Trijicon RMR tips the scale at 1.2 ounces and has dimensions of 1.8 x 1.2 x 1.0 inches, making it marginally smaller and lighter than the Holosun 507C, which weighs 1.5 ounces and measures 1.8 x 1.15 x 1.15 inches.

The RMR’s concise size and lessened weight could be more suitable for compact pistols or for those who prefer a less hefty firearm. However, the difference is so slight that it won’t usually be a factor. Both are compact red dot sights that are ideal for any handgun.

Reticle Options

The Holosun 507C’s reticle is a wonder in flexibility. Incorporating a Multiple Reticle System (MRS), the reticle is in the form of a 2 MOA dot and 32 MOA circle. This allows me to determine the type of aiming point that I need to use in a particular situation. The circle acts as a hold-over reference, aiding me in getting a sight picture faster, guiding my eye to the dot, while the dot is superimposed on the target itself. The circle can be deactivated, leaving only the dot for an uncluttered sight picture.  

As mentioned earlier, the reticle automatically switches off after a prolonged period to conserve battery. However, the dot can be revived by the slightest movement thanks to Holosun’s Shake Awake technology.

A green dot Holosun 507C is also available if you don’t prefer the red one. 

On the other hand, the Trijicon RMR offers a bright and sharp 3.25 MOA dot for accurate and rapid target acquisition. The reticle is generated by a tritium-phosphor LED lamp.

When it comes to reticle options, the Holosun 507C is the clear winner as it has multiple options.

Field of View

The Holosun 507C, with its slightly larger window size and slightly more spherical shape, delivers a broad field of view. This is ideal for fast-paced shooting scenarios in both obstacle shooting and actual law-enforcement duties where speed is essential. 

The slightly narrower field of view provided by the Trijicon RMR is advantageous for accuracy-focused shooting. It facilitates a concentrated focus on the reticle and target, reducing potential distractions.

Both devices perform admirably when it comes to visual clarity. Both lenses are resistant to smudges and don’t cloud even in cold, wet conditions.

Mounting Footprint

Both of these sights employ the same RMR footprint, a design widely recognized and accepted by the majority of firearms. Due to this, you’ll find it straightforward to attach either of these sights to your weapon.

The RMR footprint has gained popularity over time, resulting in an extensive range of aftermarket mounts. This is good news if you’re interested in customizing your setup—both options should serve you well. Both the Holosun 507C and the Trijicon RMR provide a versatile and user-friendly mounting footprint, marking them as exceptional selections.

Solar Panel Technology

This is another win for the Holosun 507C. This sight is equipped with a small solar panel on top of the lens arc. It serves a dual purpose; it extends battery life and powers the sight when there’s sufficient light. This is the core technology that enables the 507C to have a whooping battery life of up to 50,000 hours.

Note that just like any solar powered device, the solar panel ceases to function in poorly lit conditions, causing the sight to rely on battery power. 

The RMR lacks this solar feature; there’s no secondary power source should the batteries run out. Its power-saving feature somewhat counteracts this drawback, but the Holosun 507C has both this innovation and solar panels.

Price Comparison

Despite its superlative features, the Holosun 507C often emerges as the less expensive alternative when pitted against the Trijicon RMR. The price range for the Holosun 507C usually hovers around $280 to $330 whereas a new Trijicon RMR could cost anywhere from $450 to $700.

Note that these prices aren’t set in stone and may vary depending on where you make the purchase. Yet, it’s evident that for those who are mindful of their spending, the Holosun 507C proves to be a more budget-friendly pick.

The Trijicon RMR’s higher cost is justified by its military-grade robustness, its wide adoption among law enforcement agencies, and its solid track record for dependability.

Putting the Holosun 507C and the Trijicon RMR side by side, it’s clear that the 507C has an edge in the red dot sight market. This is mainly due to its many features—the Shake Awake technology, Solar Failsafe, multiple-reticle options, and extremely long battery life. For many shooters, these features are already winners.

The RMR does have an advantage in terms of weight, size, and durability. This makes the RMR the preferred choice of law enforcers and military operatives. 

Taking into account the cost factor, the Holosun 507C offers excellent value for money, making it a more appealing choice over the Trijicon RMR in my perspective when it comes to causal or competitive shooting, hunting, sports, home defense, and other recreational applications.

But for those who are into more dynamic and tactical shooting, the RMR takes precedence.
