Why Trust Holosun for Concealed Carry?
Holosun has earned a strong reputation among concealed carriers, law enforcement professionals, and competitive shooters by producing reliable, feature-rich red dot sights at competitive prices.
The brand is known for innovations such as Shake Awake™ technology, Solar Failsafe™, long battery life, and durable 7075-T6 aluminum or Grade 5 titanium housings.
Many Holosun optics also feature enclosed emitters that protect against lint, dust, and moisture—ideal for everyday carry.
Combined with clear glass, dependable zero retention, and compatibility with many popular concealed carry pistols, Holosun red dots deliver the performance, durability, and value that defensive shooters can trust.
Open Emitter vs. Enclosed Emitter: Which Is Better for Concealed Carry?
One of the most important choices to make when selecting a Holosun red dot for concealed carry is whether to purchase an ‘open-emitter’ or ‘enclosed-emitter’ optic.
Open-emitter models (e.g., the Holosun 407K X2, Holosun 507K X2, and Holosun 507C X2/X3 are examples) feature an exposed LED that illuminates the reticle onto the lens. They tend to be lighter, less expensive, and have a great “sight picture,” so they’re popular for the daily carrier.
Enclosed-emitter optics, such as the Holosun EPS Carry, SCS Carry, and 509T X2, completely cover the emitter within the housing. The design keeps lint, dust, mud, rain, and moisture from obstructing the reticle, for increased reliability in adverse conditions.
Which Holosun Footprint Does Your Pistol Use?
When purchasing a Holosun red dot, you should make sure that the optic’s mounting footprint is compatible with your pistol’s optics cut. Selecting the right footprint makes it easy to install the sight, since no changes are needed and no incompatible adapter plates will be used.
Holosun’s K footprint is the most common for micro-compact pistols such as the Glock 43X MOS, Glock 48 MOS, SIG Sauer P365 series, Springfield Hellcat and Smith & Wesson Shield Plus.
This footprint is used by optics like the EPS Carry, 407K X2, 507K X2, and 407K SCS Carry, but others may need an adapter plate or minor adjustments.
Often, larger handguns such as the Glock 19 MOS, Glock 17 MOS, Shadow Systems MR920, and Walther PDP employ the Trijicon RMR footprint. Holosun’s popular 507C X2/X3 and 508T X2 are directly attached to these slides or compatible plates.
509T X2 mounts to many optics-ready pistols with an included RMR-to-509T adapter plate, and features Holosun’s exclusive 509T footprint. Check the handgun optics fit before buying, as it is crucial for a proper fit and performance

1) Holosun EPS Carry
Price on Amazon & Price on Opticsplanet
Featuring a fully enclosed emitter design and a compact size for easier concealed carry, the Holosun EPS Carry is considered one of the top red dot sights for concealed carry.
The EPS Carry is unlike conventional open-emitter pistol optics because it keeps the LED inside the housing; that way, lint, dust, sweat, rain, and other debris will not block the emitter.
This makes it particularly ideal for everyday carry, as the optic is continually exposed to fibers from clothes and the elements.
Designed to fit slim and subcompact pistols, with a Holosun K footprint and an RMSc-to-K adapter plate for greater compatibility.
Ultra-low deck height is ideal to co-witness with numerous factory iron sights, and the aspherical glass lens delivers a crisp, distortion-free sight picture.
Shooters can select from a 2 MOA dot, a 6 MOA dot, or a Holosun Multi-Reticle System (MRS), a combination of a 2 MOA dot with a 32 MOA circle, which allows shooters to acquire targets more quickly.
A side-loading CR1620 battery can deliver up to 50,000 hours of operation without having to remove the optic to change the battery, keeping zero in check. The EPS Carry’s 7075-T6 aluminum construction, along with its IPX8 waterproof rating, guarantees reliability for personal defense and concealed carry.

Factors to Consider When Choosing The Best Holosun Red Dot for Concealed Carry.
Although all Holosun optics are known for their reliability and innovative features, there are several things that can help you choose the model that is best suited for your everyday carry (EDC) needs.
- Open vs. Enclosed Emitter
The selection of either an enclosed-emitter or an open-emitter optic is one of the most crucial choices. Generally lighter and slightly less costly, open-emitter models such as the 507K X2, 507C X2/X3, and 508T X2 provide excellent performance.
They can, however, trap lint, dust, rain, or debris on the exposed emitter. Enclosed-emitter models like the EPS Carry, SCS Carry, and 509T X2 offer better protection from the elements and are perfect for everyday concealed carry where you’re always in contact with the fibers in your clothes and the weather.
- Footprint Compatibility
Not all Holosun optics will fit all handguns. Micro-compacts may have a “Holosun K footprint”; larger pistols may have a “RMR footprint”. Mounting is via a proprietary system in the 509T; adapter plates are available. When buying, always check that your pistol’s optics cut.
- Reticle Options
Holosun has several reticle options. A 2 MOA dot is very accurate for distance shots, and a 6 MOA dot is for close-range defensive situations. The Multi-Reticle System (MRS) is a feature found on models that allows you to choose between a 2 MOA dot, 32 MOA circle, or a mix of both.
- Size and Weight
If you are opting for concealed carry, smaller and lighter optics will likely be less cumbersome and won’t print as easily under clothing. Compact models, like the EPS Carry, 507K X2 and SCS Carry, are great for slim pistols, while larger optics, like the 507C, 508T and 509T, are better suited for compact and full-size handguns.
- Durability
Durability is important if you’re going to use your handgun for a lot of training, rough conditions, or professional shooting.
- The battery system and runtime.
The majority of Holosun optics feature a side-loading coin-cell battery for up to **50,000 hours** of battery life. Special features such as Shake Awake™ can help save power by automatically turning on the reticle when the camera begins to move.
- Budget
Holosun’s products come in different quality ranges. The 407K X2 is a great budget option and the 507K X2 offers great value with its Multi-Reticle System.
Premium options like the EPS Carry, SCS Carry, 508T X2 and 509T X2 cost more but offer more features like enclosed emitters, titanium construction, or solar charging that make them worth the upgrade for many concealed carriers.
FAQs
- Which Holosun red dot is best for concealed carry?
The Holosun EPS Carry is widely considered the best overall Holosun red dot for concealed carry. Its fully enclosed emitter protects the LED from lint, dust, sweat, and moisture, while its compact size, long battery life, and durable construction make it ideal for everyday carry.

- What’s the difference between the Holosun 407K and 507K?
The primary difference is the reticle. The 407K X2 features a single 6 MOA dot, while the 507K X2 includes Holosun’s Multi-Reticle System, allowing you to switch between a 2 MOA dot, a 32 MOA circle, or a circle-dot combination.
