Holosun 407C Green Dot vs Red Dot
Many users ask whether they should get the Holosun-407C green or red dot.
Let’s compare:
| Feature | Green Dot | Red Dot |
|---|---|---|
| Brightness in daylight | Better in bright light | Good but not as bright |
| Eye comfort | Easier on eyes | More common/traditional |
| Battery Life | Slightly lower | Slightly higher |
If you shoot mostly outdoors, the Holosun-407C green dot might be better. For general use, red dot is fine and more affordable.
Holosun 407C Footprint and Mounting
The Holosun-407C uses the Trijicon RMR footprint. This is important because many pistols and mounts are already compatible with RMR. You won’t need a special adapter. It’s easy to mount on slides cut for RMR or plates supporting RMR-style optics.
Holosun 407C X2 Version Explained
The Holosun-407C X2 is the updated version of the original 407C. What’s new?
-
Improved buttons with better tactile feedback
-
Lock mode to prevent accidental setting changes
-
Slight tweaks in brightness controls
In short, the X2 is just a more refined version. If you’re buying new, go for the 407C X2.
Holosun 407C vs 507C: Key Differences
A big question is: What is the difference between Holosun-407C and 507C?
| Feature | Holosun 407C | Holosun 507C |
|---|---|---|
| Reticle | 2 MOA Dot | 2 MOA Dot + 32 MOA Ring |
| Price | Lower | Higher |
| Use Case | Simpler, straightforward | More flexible (multiple reticles) |
The 507C offers multi-reticle options, which some users love. But if you want a basic and clear dot, the 407C is cheaper and just as tough.
Holosun 407C vs 407K: Which One Is Better?
The Holosun-407C vs 407K debate usually comes down to gun size.
| Feature | Holosun 407C | Holosun 407K |
|---|---|---|
| Mount Footprint | RMR | RMSc |
| Size | Larger | Compact |
| Use | Full-size pistols | Subcompacts |
Choose the 407C for full-size handguns or rifles. Pick the 407K for small carry guns.

Holosun 407C Torque Specs for Mounting
If you’re mounting the 407C on your slide or a mount, use 15 in-lbs of torque on the screws.
Use Loctite (blue threadlocker) to secure them.
Over-tightening can damage the optic or strip the threads, so follow the torque specs carefully.

Always check the fit before live fire.
