Hey there, shooters!
Joshua Stevens here, bringing you another Tech Tip Tuesday. Today, we’re diving into the world of pistol-mounted optics and dissecting the differences between closed and open emitter designs. With more shooters opting for red dot sights on their handguns, understanding the pros and cons of each type can help you make the best decision for your needs. Let’s get into it.
Closed Emitter Optics: Rugged and Reliable
First up, let’s talk about closed emitter optics. These are designed with an enclosed housing that protects the emitter from the elements. The Holosun EPS Carry and EPS are prime examples of this type of optic. I’ve mounted these on both my pistols and rifles, and they’ve consistently proven their worth in various conditions and are currently my favorite enclosed optics to run.
The Advantages
- Rugged Design: The enclosed nature of these optics means they’re less susceptible to dirt, dust, rain, and snow. This makes them incredibly rugged and reliable, especially in harsh environments. If you’re like me and often find yourself in unpredictable conditions, this is a significant advantage.
- Ease of Maintenance: With closed emitters, cleaning is straightforward since the emitter is protected inside the housing. You don’t have to worry about debris affecting the dot, which means less downtime and more shooting time.
- Durability: The enclosed design generally means that these optics are built to withstand more abuse. Whether you’re dropping your gun or it’s getting banged around in a holster, the closed emitter optic is more likely to keep functioning without a hitch.
A swipe of your thumb or a cleaning cloth is all you need to remove even the worst debris from the glass of your enclosed emitter. Even dried on mud comes right off easily.
The Trade-offs
Of course, no piece of equipment is perfect. Closed emitter optics tend to be bulkier and heavier due to the additional materials used to protect the emitter. This added weight can affect the balance of your pistol, and the bulkier design may not be as sleek or low-profile as some shooters prefer. However, for me, the trade-off is worth it for the increased ruggedness and reliability.
Open Emitter Optics: Field of View and Speed
On the flip side, we have open emitter optics. These designs leave the emitter exposed, which can offer some distinct advantages. I personally use the Holosun 507 Comp on my competitive shooting pistol, a CZ Shadow 2, and it’s been a game-changer for my performance.
The Advantages
- Wider Field of View: Open emitter optics typically provide a larger window, giving you a broader field of view. This is particularly beneficial in competitive shooting where speed and accuracy are paramount. The Holosun 507 Comp, for instance, offers a wide, clear view that helps me acquire targets quickly and transition between them smoothly.
- Lighter Weight: Without the extra housing materials, open emitter optics are generally lighter. This can help maintain the balance of your pistol and reduce fatigue during extended shooting sessions. It’s also important for meeting IDPA weight requirements.
The cup like design on an open emitter means it’s much harder to clean in the field requiring tools and frustration. It’s also a cup that like to hold dirt and debris.
The Trade-offs
However, the open design also means the emitter is exposed to the elements. Dirt, dust, and water can interfere with the dot, potentially causing issues during use. This makes maintenance a bit more involved as you’ll need to clean the emitter regularly to ensure it remains clear and functional. Additionally, open emitters are generally less durable than their enclosed counterparts, so they may not be the best choice for rough or unpredictable environments.
Making the Choice: Closed vs. Open Emitter

When deciding between closed and open emitter optics, it ultimately comes down to your specific needs and preferences. Here’s a quick breakdown to help guide your decision:
- Choose Closed Emitter Optics if:
- You need a rugged, reliable optic that can withstand harsh conditions.
- Ease of maintenance is a priority.
- You don’t mind a bit of extra weight and bulk for increased durability.
- Choose Open Emitter Optics if:
- You prioritize a wider field of view for quick target acquisition.
- You prefer a lighter, more streamlined optic.
- You shoot primarily in controlled environments where debris and weather are less of a concern.
Personal Preferences and Recommendations
Personally, I lean towards closed emitter optics like the Holosun EPS Carry and EPS for most of my firearms. The added protection and reliability give me peace of mind, knowing my optic will perform regardless of the conditions. Whether I’m out in the field or on the range, these optics have never let me down.
However, for competitive shooting, the Holosun 507 Comp on my CZ Shadow 2 is my go-to. The wide field of view and lighter weight help me stay quick and accurate during matches. The choice really comes down to the application and what you value most in your optic.
