Holosun 507C X2
Holosun disrupted the pistol optic market by offering premium features at mid-range prices. The 507C X2 has become the go-to choice for concealed carriers and competition shooters who want the most features per dollar.
Pros
- Multi-reticle system (dot, circle, or both)
- Solar failsafe—works even if battery dies
- Shake awake preserves battery life
- Side-loading battery—no re-zero needed
- Larger window than RMR
- Excellent value (~$310)
Cons

- Made in China
- 3-year warranty (vs lifetime)
- Some agencies don't approve non-US optics
Durability Testing
Both optics are built on 7075 aluminum housings and pass standard drop tests. However, the RMR has decades of documented combat use, while the Holosun is relatively newer. Independent torture tests show both survive extreme abuse, but the RMR's track record is longer.
For duty use where your life depends on the optic, the RMR's proven history matters. For concealed carry and range use, the Holosun is more than durable enough.
Battery Considerations
The Holosun's side-loading battery tray is a significant advantage. You can swap batteries without removing the optic or losing zero. The RMR's bottom-loading battery requires removing the optic, which means re-zeroing.
The Holosun's shake awake feature extends battery life dramatically—the optic sleeps when motionless and instantly wakes when moved. The RMR is always-on, which some users prefer for duty reliability.
Reticle Options
The Holosun 507C offers three reticle modes:
- 2 MOA dot only — Precision aiming
- 32 MOA circle only — Fast acquisition
- Circle + dot — Best of both
The RMR is available in fixed reticle sizes (1, 3.25, or 6.5 MOA). Most users choose 3.25 MOA as a balance between speed and precision. You must decide at purchase—no switching.
Which Should You Buy?
Choose the Trijicon RMR if:
- You're law enforcement or military
- Your agency requires US-made optics
- Absolute reliability is non-negotiable
- You want the proven industry standard
- Budget isn't your primary concern
Choose the Holosun 507C if:
- You want the most features for your money
- Side-loading battery matters to you
- You prefer the circle-dot reticle option
- You're a concealed carrier or competitor
- You want solar backup and shake awake
Conclusion
Both are excellent pistol optics. The Trijicon RMR remains the gold standard for duty use—proven, durable, and trusted worldwide. The Holosun 507C offers more features at 60% of the price, making it the better value for most civilian shooters.
