- Proven track record in harsh environments.
Cons:
- Bottom-loading battery requires re-zeroing after changes.
- Smaller window compared to competition.
My hands-on notes:When testing the RMR Type 2, the first thing I noticed was the absolute rigidity of the housing. On a Charter Arms Double Dog, which can be snappy, the RMR holds its zero without a hint of shift. The parallax is negligible within standard defensive distances, and the glass tint, while slightly blue, helps enhance dot contrast in bright sunlight. The buttons are tactile enough for use with light gloves, though they are recessed to prevent accidental changes.
What people say online:Users across various forums praise the RMR for being "bomb-proof." The consensus is that while the battery placement is annoying, the peace of mind you get from its reliability is unmatched. It’s frequently cited as the top choice for any firearm intended for self-defense or duty use.
Mounting clarity:This optic uses the RMR footprint. For the Charter Arms Double Dog, you will likely need a specific Picatinny rail adapter or a custom-milled plate depending on your specific rail setup.

Holosun 507K ACSS
The Holosun 507K ACSS stands out because of its specialized Vulcan reticle system. Unlike standard dots, the ACSS reticle features a large outer circle that guides your eye to the center dot if you are misaligned—a massive benefit when drawing a revolver from a holster.
Specs:
- Reticle: ACSS Vulcan (Dot and large circle)
- Battery: CR1632
- Housing: 7075 T6 Aluminum
- Shake Awake: Yes
- Brightness Settings: 12 (including 2 NV)
Pros:
- Incredible target acquisition for beginners.
- Side-loading battery tray.
- Compact footprint fits smaller frames well.
Cons:
- The large circle reticle can feel cluttered for some.
- Not as "over-built" as an Aimpoint or Trijicon.
My hands-on notes:The ACSS reticle is a game-changer for high-stress scenarios. In my testing, even when I intentionally held the gun at an awkward angle, the outer ring immediately showed me where I needed to adjust. The deck height is impressively low, which may allow for a partial co-witness with certain iron sight setups. The glass is remarkably clear with very little distortion at the edges.
What people say online:Reddit discussions often highlight the "cheat code" nature of the ACSS reticle. New shooters find it significantly easier to use than a standard 2 MOA dot. Some long-term users have noted that Holosun’s "Shake Awake" feature is extremely reliable, saving battery life without sacrificing readiness.
Mounting clarity:Uses the Shield RMS/RMSc footprint. Check your mounting rail; an adapter plate is standard for most multi-fit applications.

Leupold Deltapoint Pro
The Leupold Deltapoint Pro is famous for its massive, crystal-clear window. If you struggle with "tunnel vision" when using small red dots, the DPP offers a much more expansive view of your target, which is essential for a defensive revolver like the Charter Arms.
Specs:
- Reticle: 2.5 MOA Dot
- Battery: Top-loading CR2032
- Housing: Aluminum with Steel Shroud
- Sensor: Motion Sensor Technology (MST)
- Adjustment: 1 MOA clicks
Pros:
- Best-in-class glass clarity and window size.
- Top-loading battery is very convenient.
- Excellent for shooters with astigmatism.
Cons:
- Higher deck height can make co-witnessing difficult.
- Brightness adjustment is a single-button cycle.
My hands-on notes:The window on the DPP is simply gorgeous. It feels less like looking through a tube and more like a heads-up display. On the Charter Arms Double Dog, the taller deck height is noticeable, so you'll need to practice your "bore-to-sight" offset at close ranges. The MST (Motion Sensor Technology) is flawless, shutting the unit down to save battery and waking it up at the slightest movement.
What people say online:Common feedback centers on the glass quality, with many claiming it's the only dot they can use comfortably with an astigmatism. Some critics point out that the single-button interface for brightness can be tedious if you need to change settings rapidly.
Mounting clarity:Uses the DeltaPoint Pro footprint. This is a very common standard, and finding a rail adapter for a revolver is generally straightforward.

My hands-on notes:Shooting with the ACRO P-2 feels like using a miniature rifle optic. The enclosed design means you never have to worry about a flake of lint or a drop of rain blocking the emitter. The dot is incredibly crisp, and the digital intensity buttons are the best in the business—easy to find and very tactile. On a Charter Arms, it adds a bit of weight, which actually helps slightly with recoil management.
What people say online:The P-2 is widely regarded as the most durable handgun optic on the market. "Set it and forget it" is the common mantra among owners. While people joke about the boxy look, they stop laughing when they see how well it performs in mud, snow, and rain.
Mounting clarity:Uses a proprietary ACRO rail system. You will definitely need an adapter plate to mount this to a standard Picatinny or Weaver rail.

Vortex Defender CCW
The Vortex Defender CCW was built from the ground up for concealed carry and everyday reliability. It features a unique "ShockShield" polymer insert to soak up impacts and a textured front face (FastRack) that allows you to rack a slide—or in this case, handle the gun—without slipping.
Specs:
- Reticle: 3 MOA or 6 MOA Red Dot
- Battery: Top-loading CR1632
- Auto-Shutoff: Yes (Motion activated)
- Lens: Aspherical for distortion-free viewing
- Footprint: Shield RMS/RMSc

How I Tested / Evaluation Criteria
- Parallax: I tested each optic by securing it in a vice and moving my eye across the window at various distances. A high-quality red dot should show minimal dot movement relative to the target, ensuring that even with an imperfect cheek weld, your shot remains true.
- Co-witness / Deck Height: I measured the distance from the base of the optic to the center of the window. For the Charter Arms Double Dog, a lower deck height is generally preferred to keep the line of sight as close to the factory iron sights as possible.
- Durability: While I didn't perform "torture tests," I evaluated the housing material (7075-T6 aluminum vs. standard alloys) and the presence of protective shrouds. I also considered the recoil rating to ensure the electronics can withstand the sharp snap of a revolver.
- Battery: I looked for side-loading or top-loading compartments to avoid the hassle of re-zeroing. I also verified the manufacturer’s battery life claims against known user experiences and tested the responsiveness of "Shake Awake" or motion-sensing features.
- Brightness Range: Each optic was tested in low-light conditions to check for "bloom" and in direct midday sun to ensure the dot remained visible. The number of night vision (NV) settings was also recorded for those using tactical gear.
- Glass Quality: I checked for lens tint, edge-to-edge clarity, and the presence of aspherical elements. Good glass should not have a heavy blue or green tint that obscures the target in dim light.
- Controls Ergonomics: I manipulated the brightness buttons with bare hands and heavy gloves. Tactile feedback is crucial so the shooter knows a change has been made without needing to look at the buttons.
- Mounting Ecosystem: I researched the availability of plates and the commonality of the footprint. An optic is only as good as its connection to the firearm, so a secure mounting system is paramount.
How to Choose the Right Red Dot for This Gun
Choosing the Best Red Dot for Charter Arms Double Dog involves balancing the firearm's compact nature with the need for a robust sighting system. The first decision you must make is between an open-emitter and an enclosed-emitter optic. Open emitters, like the Trijicon RMR or Leupold DPP, offer a larger field of view and a lower profile, which is excellent for concealed carry. However, if you plan to use your Double Dog for hiking or hunting in inclement weather, an enclosed emitter like the Aimpoint ACRO P-2 or the Sig Romeo2 (in its enclosed configuration) is superior because it prevents debris or water from blocking the laser that projects the dot.
Secondly, consider the reticle size. A smaller 2.5 or 3 MOA dot is better for precision at longer distances, but a 6 MOA dot or a circle-dot reticle (like Holosun’s ACSS) is much faster for close-quarters defensive situations. Because the Double Dog is often used as a defensive tool, the faster acquisition of a larger reticle or a guidance system is usually the wiser choice.
Finally, do not overlook the mounting footprint. The Charter Arms Double Dog doesn't always come with a standard optics cut, meaning you will likely be using a rail adapter. Ensure that the optic you choose has a widely supported footprint (like RMR or Shield RMS) so that finding a high-quality, low-profile rail mount is easy. A mount that sits too high will ruin the balance of the gun and make it difficult to find the dot quickly. Always prioritize a setup that keeps the optic as low to the frame as possible to maintain a natural point of aim.
FAQs
1. Does the Charter Arms Double Dog have a specific footprint?Most Double Dog models require a Picatinny or Weaver rail adapter to be installed on the top strap. From there, you use a mount that matches your specific red dot's footprint (RMR, Shield, etc.).
2. Will a red dot handle the recoil of a .357 Magnum or .44 Special?Yes, but you must choose a high-quality optic. Budget-tier dots often have internal components that can shake loose under heavy revolver recoil. Stick to the brands listed in this guide.
3. What is "deck height" and why does it matter?Deck height is the thickness of the optic's base. A lower deck height allows the red dot to sit closer to the bore, making it easier to transition from iron sights to the electronic dot.
4. Can I still use my iron sights with a red dot?This depends on your mount and the optic's deck height. "Co-witnessing" is often difficult on revolvers unless you use a very low-profile micro-dot and a specialized mount.
5. How often should I change the battery?Even if an optic claims 50,000 hours of battery life, it is a best practice to change the battery once a year on your birthday or another memorable date to ensure it never fails when you need it.
Conclusion
The Best Red Dot for Charter Arms Double Dog is ultimately the one that fits your specific mission, whether that’s home defense, trail protection, or range fun. The Trijicon RMR Type 2 remains the king of durability, while the Holosun 507K ACSS offers the best assistance for rapid acquisition. If glass clarity is your top priority, the Leupold DeltaPoint Pro is hard to beat. Regardless of your choice, adding a red dot to your Double Dog will significantly increase your accuracy and confidence, turning a classic-style firearm into a modern precision tool. Consistent training with your chosen optic is the final step in mastering this rugged platform.
