Holosun 507COMP Overview

The Holosun 507COMP is the better choice if you want maximum reticle flexibility. Its PRS reticle system gives you a 2 MOA dot with selectable 8 MOA, 20 MOA, and 32 MOA circle options.

That makes it a strong competition optic for shooters who want to tune their sight picture based on stage layout, target distance, and personal preference. The large window also helps with dot tracking during recoil and fast target transitions.

Choose the 507COMP if you want:

A large competition window
Selectable PRS reticle options
A 2 MOA dot with multiple circle choices
More flexibility for competition and range use
Red, green, or gold reticle variants

Holosun 407COMP Overview

The Holosun 407COMP is the better choice if you want a simpler competition optic. Instead of multiple reticle options, it gives you a clean 6 MOA dot.

That larger dot is easy to pick up quickly and keeps the sight picture simple. For shooters who do not want to cycle through reticle settings or think about circle sizes, the 407COMP makes a lot of sense.

Choose the 407COMP if you want:

A simple 6 MOA dot
A large competition window
No selectable reticle system
A clean sight picture for fast shooting
Red, green, or gold dot variants

PRS Reticle vs 6 MOA Dot

The reticle is the main reason to choose one optic over the other.

Reticle feature	Holosun 507COMP	Holosun 407COMP
Dot size	2 MOA dot	6 MOA dot
Circle options	8 MOA, 20 MOA, and 32 MOA circle options	None
Circle-dot option	Yes	No
Best advantage	Flexible sight picture	Simple, fast dot pickup
Best buyer	Shooter who likes tuning reticles	Shooter who wants one simple dot

The 507COMP is better if you like experimenting with reticles. A smaller dot can be useful for more precise aiming, while the circle options can help with speed and visual tracking.

The 407COMP is better if you already know you want a bold dot-only setup. The 6 MOA dot is easy to see and easy to run fast, especially in a competition environment.

Footprint and Fitment

Both optics use the RMR footprint. That makes them compatible with many optics-ready pistol slides, competition slides, and adapter plates built around the RMR mounting pattern.

Before ordering either optic, confirm your slide cut, adapter plate, screw length, and optic mounting system. “RMR footprint” is a strong starting point, but the exact pistol and plate setup still matters.

Battery Life and Controls

Both optics use a CR1632 battery with a side-loading battery tray. That means the battery can be replaced without removing the optic from the pistol.

The 507COMP is rated up to 50,000 hours of battery life. The 407COMP is rated up to 100,000 hours. Real-world runtime depends on reticle color, brightness setting, and use.

Both optics also include Shake Awake, manual brightness controls, memory, and lockout mode. Those features are useful on a competition optic because they help keep the optic ready while reducing accidental setting changes.

Holosun 507COMP and 407COMP Differences

The real difference is the reticle system. The 507COMP gives you more reticle choices. The 407COMP gives you a simpler 6 MOA dot.

Difference	Holosun 507COMP	Holosun 407COMP
Reticle system	PRS selectable reticle	Single dot reticle

Red, Green, and Gold Reticle Options

Both the 507COMP and 407COMP are available in red, green, and gold reticle variants depending on model and inventory.

Red is the traditional choice and works well for most shooters. A green dot variant can appear brighter or easier to pick up for some eyes. Gold gives shooters another contrast option if red or green does not stand out the way they want.

If you have astigmatism, reticle color is personal. Some shooters see less starburst or distortion with green or gold, while others prefer red. Dot size, brightness setting, reticle shape, and your individual eyesight all affect how the reticle appears.

Is the Holosun 507COMP Worth It Over the 407COMP?

The 507COMP is worth it if you want the PRS reticle system. If you plan to use the circle options, want a smaller 2 MOA dot, or like tuning your reticle for different stages, the 507COMP makes sense.

The 407COMP makes more sense if you already know you want a 6 MOA dot. If you do not care about selectable reticles, the 407COMP gives you the same large competition window in a simpler package.

Which One Should You Choose?

Choose the Holosun 507COMP if you want a competition pistol optic with multiple reticle options, a 2 MOA dot, and selectable 8, 20, or 32 MOA circle choices.

Choose the Holosun 407COMP if you want a simpler competition pistol optic with a bold 6 MOA dot and no selectable reticle system.

Both are strong competition red dots. The right choice depends on whether you want reticle flexibility or dot-only simplicity.
