Description
Holosun HS507C-X3 Red Dot Sight is the version of this sight most people end up buying, and the reason is the Multi-Reticle System: a 2 MOA dot for precision, a 32 MOA circle for speed, or the circle-dot when you want both, all on one button. The X3 generation sharpens the glass over the X2 behind the same 0.91 × 0.67 in window.
How It Compares
Only ever use one reticle? The single-dot HS407C-X3 is the simpler buy. Green and gold emitters are the HE507C-X3 Green and Gold. Our pistol red dot picks put it in context.
Ideal For
- Optics-ready pistols cut for the RMR
- One optic covering carry, range and competition
- Shooters who want the current generation

Help & guidance
Product FAQs
Should I buy the HS507C-X2 or the HS507C-X3?
The HS507C-X3 is the newer generation with refined optics, sharpening the glass over the X2 behind the same 0.91 x 0.67 in window. Both share the Multi-Reticle System and Solar Failsafe.
Which reticle should I zero the HS507C-X3 with?
Use the 2 MOA dot on the Holosun HS507C-X3 for zeroing, as it is the finest of the three reticles and gives the clearest reference on a zeroing target. You can switch back to the circle or circle-dot afterwards.
How long does the battery last in the Holosun HS507C-X3?
The HS507C-X3 is rated up to 50,000 hours on a CR1632. Solar Failsafe supplements the battery and Shake Awake stands the sight down when it is not moving.
Will the HS507C-X3 fit my pistol slide?
The Holosun HS507C-X3 uses the Trijicon RMR footprint, so it fits optics-ready slides cut for the RMR. Check your slide cut against that pattern before ordering.
What reticles does the HS507C-X3 Red offer?
The Holosun HS507C-X3 Red gives a 2 MOA dot for precision, a 32 MOA circle for speed, or the circle-dot when you want both. All three are selected with one button.
What emitter does the Holosun HS507C-X3 Red use?
The HS507C-X3 Red uses a 650 nm red Super LED of the X3 generation. It is a 1x sight, parallax-free with unlimited eye relief.
How big is the HS507C-X3 window?
The viewing window on the Holosun HS507C-X3 measures 0.91 x 0.67 in, which is 23 x 17 mm. The X3 generation sharpens the glass behind that same window size.
Where does the battery go in the HS507C-X3?
The CR1632 in the Holosun HS507C-X3 loads from the side of the housing. That means the battery can be swapped without disturbing the sight on the slide.
What are the adjustment clicks on the HS507C-X3?
Windage and elevation move in 1 MOA clicks on the Holosun HS507C-X3. Total travel is plus or minus 50 MOA in both directions.
How tough is the Holosun HS507C-X3?
The HS507C-X3 uses a 7075-T6 aluminium housing rated IP67. It is intended to cover carry, range and competition in one optic.
What is in the box with the HS507C-X3?
The box holds the Holosun HS507C-X3 red dot sight, mounting hardware with a fitting tool, and a CR1632 battery.
What are the alternatives to the HS507C-X3 Red?
If you only ever use one reticle, the single-dot HS407C-X3 is the simpler buy, and the green and gold emitter versions are the HE507C-X3 Green and the HS507C-X3 Gold. The HS507C-X3 Red itself is the multi-reticle model in red.
How soon will my Holosun HS507C-X3 arrive?
