Holosun 407C vs 507C: which red dot should you buy?
Our verdict: these are the same optic with one line changed. Buy the HS407C-X2 (around $190 ) if you want a plain 2 MOA dot and would rather keep the $47. Buy the HS507C-X2 (around $230 ) only if you will genuinely use its selectable 32 MOA circle, which is faster to catch at close range. Everything else, the open emitter, the RMR footprint, the 50,000-hour CR1632 with solar failsafe and shake-awake, the 1.5 oz IP67 7075-T6 housing, is identical on both spec sheets.
Between them they carry 605 verified owner reviews on OpticsPlanet, both averaging 4.8/5. Prices verified August 18, 2026; confirm the current price on the retailer page. The 507C is our best overall pick in the best red dot sight guide.

One row is different. That is the whole comparison.
Run down the table and the pattern is hard to miss: every line matches until you hit the reticle. Same open emitter, same RMR footprint, same CR1632 running about 50,000 hours behind the same Solar Failsafe and Shake Awake, same 1.5 oz of IP67-sealed 7075-T6 aluminum, same 1 MOA clicks and 50 MOA of travel. Holosun did not build the 407C as a cheaper, weaker optic. It built the same optic with a simpler reticle.
So the honest question is not "which is better." It is will you use the circle? The 507C lets you select a 2 MOA dot, a 32 MOA circle, or the circle and dot together. The 407C gives you the 2 MOA dot, full stop.
When the 32 MOA circle earns its $47
- Close-range speed. A large ring is easier to catch on the draw than a small dot, so the circle-dot is popular for defensive and competition shooting where the first sight picture decides the shot.
- You want options. Some shooters run the circle-dot up close and switch to the bare dot for precision. If you like tuning your setup, the 507C gives you something to tune.
- Astigmatism. Some shooters whose astigmatism smears a bare dot find a large ring easier to use. It is worth knowing this is reported rather than guaranteed, and it varies by eye. Our best red dot for astigmatism guide covers what actually helps.
When the 407C is the smarter buy
- You just want a dot. If you would set a 2 MOA dot and never open the reticle menu again, you would be paying $47 for a feature you do not use.
- You are buying more than one. Outfitting two or three pistols multiplies that gap two or three times over, which buys a mounting plate or a case of ammo.
- Simplicity under stress. Fewer reticle options means nothing to accidentally change. One owner who runs both sights says the 2 MOA dot is "a nice size" and that he picks it up quickly.
"I have this and also the 507c. I don't think I can go back to a red dot that you have to turn on and off. The shake awake has never failed and it's great not having to think about turning the red dot on and off. The red dot itself is a nice size at 2 moa and I can pick it up quickly."
Most helpful positive review of the HS407C-X2, an owner of both sights, via OpticsPlanet
What owners flag on the 407C
It is not flawless, and the same complaints follow the platform. The most helpful negative review reports that the brightness buttons sit too close together, which makes adjusting the dot while looking through the window awkward, and that the battery compartment screw worked loose and was lost. That second point echoes what owners say about the 507C, where the battery-tray screw is small and easy to strip if overtightened. Neither sight ships with a mount or plate, so budget for one matched to your pistol's cut.
Carrying a sub-compact pistol? Then the reticle is the second question and the body is the first, because these C-body sights use an RMR footprint that a P365 or Glock 43X slide is not cut for. The K-body versions are, and they are a different purchase: our Holosun 407K vs 507K decoder puts all four optics side by side and shows the part that surprises most buyers, which is that the smaller K optic costs more than the full-size 407C on this page.
FAQ
What is the difference between the Holosun 407C and the 507C?
The reticle, and almost nothing else. The HS407C-X2 gives you a single 2 MOA dot. The HS507C-X2 gives you a selectable 2 MOA dot, a 32 MOA circle, or the two combined as a circle-dot. Everything else on the two spec sheets matches: both are open-emitter 1x sights on the RMR footprint, both run a CR1632 for about 50,000 hours with solar failsafe and shake-awake, both weigh 1.5 oz in an IP67-sealed 7075-T6 housing, and both adjust in 1 MOA clicks. The 507C sells for under $50 more, and that difference buys you nothing but the extra reticle options.
Is the 507C worth the extra money over the 407C?
Only if you will actually use the circle. The 32 MOA ring is faster to catch on the draw at close range, which is why many defensive and competition shooters like it, and it gives you a second aiming option if you want one. If you shoot with a plain dot and never touch the reticle menu, the 407C is the same optic for about $47 less. Buying two or three optics for multiple pistols makes that difference add up quickly.
Do the 407C and 507C fit the same pistols and mounts?
Yes. Both use the RMR footprint, so they drop onto the same RMR-cut slides and the same standard offset or absolute co-witness AR mounts, with no difference in the plate you need. Note that neither one includes a mount or plate: OpticsPlanet lists "Mount Not Included" for the 407C, and a plate matched to your specific pistol cut is a separate purchase for either sight.
Is the 407C an enclosed emitter sight?
No. This is a common mix-up. OpticsPlanet lists the HS407C-X2 as an open emitter and describes it as an open-reflex sight, the same construction as the 507C. Both have an exposed emitter that can theoretically be blocked by heavy mud, snow or lint. If you specifically want a sealed, enclosed-emitter Holosun, the 407C is not it; that is a different product line.
Do both have solar and shake-awake?
Yes, both. Each carries Holosun's Solar Failsafe, which runs the dot off the solar panel if the battery dies, and Shake Awake, which wakes the sight on the slightest motion and sleeps it when still. Both quote about 50,000 hours from a single CR1632. One owner who runs both says the shake-awake has never failed him and that he cannot go back to a dot he has to switch on and off.

The HS507COMP gives you about 67 percent more window and 8/20/32 MOA rings, but drops the solar panel to do it.
