Intro

This is a review of the Holosun 507c open reflex optical sight. The HS507c is a red dot sight designed for pistols and features the Holosun Multi-Reticle System (MRS).

Compared to the iron sights on your handgun, red dot sights offer faster target acquisition and allow you to keep both eyes on your target. Red dot sights are also relatively costly, increasing the importance of reviewing your options.

The 507c is one of several options from Holosun, along with the 407c and 510c models. All three options are open reflex sights, which means that they have a single lens. A red dot is reflected on the lens for increased accuracy and tracking.

After comparing similar products, the Holosun 507c stands out as a top choice due to its simplicity. It includes a light sensor to automatically adjust the brightness to better suit different environments. The rugged design also ensures reliable operation.

So, should you get the Holosun 507c? That depends on several factors, including your typical shooting environment, budget, and preferences. Use this Holosun 507c review to determine whether the optical sight is the right choice for your pistol.

Keep reading to explore the pros, cons, and features of the Holosun 507c.

Overview of the Holosun 507c Optical Sight

HOLOSUN HS507C X2 Circle Dot Solar Failsafe

The 507 series of optics from Holosun are open reflex micro red dot sights with a rugged design. While these optics are referred to as “red dot sights”, you can also buy models with a green light.

After mounting the sight, you can turn it on to view a red or green dot in the center of the lens. As the sights include an open reflex design, you can keep both eyes open. The parallax-free view and unlimited eye relief ensure that you can quickly acquire and track your target without bringing your gun up to your face.

Why Choose the Holosun 507c?

The Holosun 507c is one of the top red dot sights due to its compact, easy-to-use design. The latest version features a lock mode to keep you from accidentally changing the settings. The newer 507c also has the buttons conveniently placed lower on the sight and out of the way.

The Holosun 507c is also reliable. It has durable components, including aircraft-grade aluminum housing and a multi-coated lens. The design is protected against damage from dropping and accidental scratches while minimizing glare.

Main Features of the Holosun 507c

Multiple Reticle System

The Holosun 507c includes a multiple reticle system (MRS). You can easily switch between different reticle options, including:

  • 2 MOA red/green dot
  • 32 MOA circle
  • 2 MOA dot/32 MOA circle

Red dot sights are primarily used for short-range applications. The 507c has 1x magnification, which means that objects are not closer than they appear. However, the illuminated dot in the reticle allows you to easily line up your target.

2 MOA refers to the size of the dot in the reticle, which is the ideal size for close range. The smaller dot helps with the precision and accuracy of your shots. It is more visible compared to a 1 MOA dot and obstructs less of your view compared to a larger dot.

12 Different Brightness Settings

The brightness of the red/green dot is adjustable. You can choose from 12 brightness levels, including 10 daytime settings and 2 nighttime settings.

The illuminated dot becomes more difficult to see during the daytime, especially under a bright sky. However, bright light can create a glare or starburst effect when used in low-light settings. The variety of brightness options on the 507c ensures that you can find the ideal setting for any environment.

You can also allow the Holosun 507c to automatically adjust the brightness. It is equipped with a light sensor to alter the brightness for different situations.

Battery and Solar Power

Red dot sights require a battery to power the illuminated reticle. The 507c uses a single CR1632 battery with supplemental power from a solar panel on the top of the sight.

When using the medium brightness setting you can get up to 50,000 hours of use before needing to replace the battery. Depending on how often you use the sight, you may never need to replace the battery.

Yet, leaving a battery unused for long periods can cause corrosion. Luckily, the Holosun 507c includes side battery access. You can replace the battery without unmounting and remounting the sight.

The device also features an auto-awake function. Raising your gun to eye level should be enough movement to wake the sight and turn on the illuminated reticle.

Aluminum Housing and Shockproof Design

The Holosun 507c is a durable sight. It is made with aluminum components. It also features a shockproof and waterproof design. It is rated to withstand vibrations up to 5,000g and has an IP67 waterproof rating.

The IP67 rating is one of the highest levels of protection against water and moisture. Most waterproof speakers and electronics have the same rating.

The 507c is unlikely to break if dropped or temporarily submerged in water. Multi-coatings on the lens also help protect against scratches.

Unlimited Eye Relief with an Open HUD

The Holosun 507c includes the heads-up display (HUD) that most people associate with red dot sights. The open reflex design includes a rectangular window that reflects the dot, circle, or circle-dot reticle.

The hood extends in front of the lens for added protection against scratches and breakage. The window measures 0.63 x 0.91 inches, which may seem small when you first look at it. However, as you bring the gun to eye level, you can clearly see through the HUD.

The open reflex design with a parallax-free view allows you to aim with both eyes open. Keeping both eyes open allows you to retain more of your peripheral vision. You can remain aware of your surroundings without taking your eyes off your target.

The design also offers unlimited eye relief. You do not need to bring the sight closer to your face to see the dot on your target. You can still easily see the illuminated dot through the HUD with your arms extended.

Alternatives to the Holosun 507c

Before choosing the Holosun 507c, you may want to compare a few alternative options:

Holosun 510c

HOLOSUN - HE510C-GR

The Holosun 510c offers a wider view compared to the 507c model and fits rifles and carbines instead of handguns. It includes several of the same features found in the 507c sight, including multiple reticles and long battery life. It also features a more durable design, as it uses titanium in place of aluminum in several areas. However, it does not have a solar-powered backup.

Leupold DeltaPoint Pro Reflex Sight

Leupold DeltaPoint Pro Reflex Sight

The DeltaPoint Pro Reflex Sight from Leupold includes a 2.5 MOA dot with adjustable brightness. It also has a side-access battery compartment and long battery life. However, the window is slightly larger compared to the Holosun 507c. If you are worried about the size of the HUD in your red dot sight, you may prefer the larger DeltaPoint. Yet, the DeltaPoint also costs a little more and uses dials instead of buttons, which can make adjusting the settings a little more cumbersome.

Trijicon RM06-C-700672 RMR Red Dot Sight

trijicon rm06-c-700672

The Trijicon RMR red dot sight costs a little more compared to the previous recommendations. However, it is suitable for use on almost any type of firearm. Mounting adapters are available for Picatinny rails, Weaver rails, pistols, and double-barrel rifles. It also offers up to four years of continuous use with a single battery, along with auto-awake and auto-shutoff features.

Conclusion

The Holosun 507c is a quality open reflex red dot sight from one of the most popular manufacturers of open reflex sights. Holosun has a long list of comparable sights but the 507c stands out for its variety of brightness settings and solar power panel for longer battery life.

While the 507c is a durable red dot sight, the 510c from Holosun is a little more rugged. It has titanium components, including a titanium-alloy hood, but is made for rifles and carbines.

If you want a red dot sight with an unlimited field of view for your pistol, the Holosun 507c is a top recommendation. You can easily switch between the three reticle options and adjust the brightness. The locking mode and the placement of the buttons keep you from accidentally changing the settings.

The bottom line is that if you want to improve your accuracy with a pistol, consider ordering the Holosun 507c today.
