Red dot sights have exploded for pistols the past few years, and Holosun keeps leading the pack without charging ridiculous Trijicon prices. The HS507C X2 is their flagship enclosed emitter pistol optic, and in 2026 it’s one of the most popular choices for everyday carry. I have mounted dozens of red dots on handguns over twenty years, from budget trash to high end units. Being completely straight with y’all, this thing is tough. It’s reliable & feature packed and gives you premium performance for around $300 to $350. If you’re carrying a Glock, a Sig or something similar and want a RDS that survives real everyday carry, this is it.
Holosun built the HS507C X2 with a 7075 aluminum housing and enclosed emitter for protection against debris, weather and impacts. It uses the popular RMR footprint, so mounting is easy on most slide cuts.
Key features:
- 2 MOA dot with 32 MOA circle reticle options
- Shake Awake auto on/off
- Solar failsafe for backup power
- Up to 50,000 hours battery life (CR1632)
- 12 brightness settings, including night vision compatible
- Side loading battery tray, so you do not have to re-zero when swapping cells.
OpticsPlanet pricing stays $300 to $350 depending on color (black titanium gray) and promos (they also carry exclusive colors, often for lower prices). They offer bundles with mounts or extra batteries that drop the price even lower. At time of writing this article, OpticsPlanet has it listed for just $255! So grab one now here now before the prices goes back up.
I tested one on my EDC pistol a few and ran it hard through about 800 rounds at an outdoor range. I mixed in some standard self-defense hollow points with some +P loads. My torture test included some nasty humid wet conditions. I had no issues with recoil or battery drain. The shake awake feature consistently worked as expected. Groups tightened up noticeably at 10 to 25 yards compared not using a red dot. I drilled draws and transitions and it held zero just fine. The solar charger is a nice boon, but I didn’t get to test how well it kept the unit charged.
Pros and Cons of the Holosun HS507C X2 in 2026
| Pros | Cons |
|---|---|
| Enclosed emitter protects against dirt rain and impacts | Slightly bulkier than open emitter dots |
| Insane battery life up to 50k hours with solar backup | Footprint requires milling or adapter on some slides |
| Multiple reticle options dot circle or both | Not as bombproof as military spec Trijicon RMR |
| Shake Awake and side load battery no re-zero needed | Brightness steps can feel finicky in transition light |
| Tough 7075 aluminum holds zero through heavy use | Price higher than basic open dots like Romeo5 |
Compared to the Trijicon RMR Type 2 (around $500+), the HS507C gives similar durability and features for way less cash, although the Trijicon is superior with its mil/leo track record. Against the Vortex Venom or Burris FastFire 3 (open emitters cheaper), the Holosun wins on the enclosure and battery life. Versus Sig Romeo, it offers more reticle choices, and the solar takes the win. People don’t generally complain about this optic beyond the usual footprint compatibility.
The honest takeaway, this is the winner for concealed carry pistol optics. It handles recoil from 9mm +P and .45 without drifting zero, and that makes it a great choice for home defense and everyday carry. The solar backup means you’ll always be ready, even if you forget to change batteries for years. Basically, the X2 is still the gold standard for value. If you want enclosed emitter without breaking the bank this is it.
Final Thoughts for 2026
The HS507C X2 proves that you get can high end pistol RDS performance without high end prices. It holds zero great and survives the abuse of everyday carry. This one is my go-to recommendation for anyone adding a red dot to their carry gun.
