About the Holosun HE407C-GR X2
The 407C-GR X2 is Holosun's compact green-dot pistol red dot, built around the proven RMR-footprint mounting standard. A crisp 2 MOA green reticle gives you a faster eye-pickup than red in bright outdoor sunlight — green sits at the peak of human eye sensitivity, which is why it appears noticeably brighter at the same power output. Solar failsafe panel keeps the reticle lit even if your battery ever dies, and the shake-awake circuit lets you holster confident the optic will be on when you draw.
Built on Holosun's 7075 aluminum housing with sealed lens elements, the 407C-GR X2 takes pistol slide cycles in stride and runs up to 50,000 hours on a single CR1632 battery — that's over 5 years of always-on use. The X2 generation upgrades the original 407C with a clearer lens coating, more refined brightness controls (12 settings: 10 day + 2 night), and a quick-change side-mounted battery tray that means you never have to re-zero when swapping cells.
Why Pistol Shooters Choose Holosun 407C
-
Green dot at the eye's peak sensitivity. Picks up faster than red in bright sunlight — particularly noticeable on outdoor ranges.
-
Solar failsafe. Even if your battery dies in the middle of a fight, the integrated solar cell keeps the reticle lit.
-
50,000-hour battery + shake awake. Leave it on for 5+ years; the optic auto-sleeps when stationary and wakes the instant you grip the gun.
-
RMR footprint. Drop-in for Glock MOS, SIG P320 X-series, S&W M&P CORE, FN 509 Tactical — works with the holsters and slides you already own.
-
Side-tray battery. Change the CR1632 without removing the optic — your zero stays put.

Frequently Asked Questions
Red dot or green dot — does it matter?
Green sits at the peak of the human eye's color sensitivity, so it appears noticeably brighter than red at the same actual output. In bright sunlight you'll find the green dot pops faster. Indoors and in dim light the difference disappears. Personal preference — but many shooters who've tried both stay with green.
Will this fit my Glock 19 MOS?
Yes — the Glock MOS plate system includes an RMR-compatible plate. The 407C-GR X2 mounts directly using Glock's #04 mounting plate (or some shooters direct-mill the slide). Confirm your MOS plate is RMR-pattern; standard Glock MOS kits include one.
Do I really need backup iron sights?
Strongly recommended. Even with solar failsafe and 50K-hour battery, optics can fog up, get knocked out of zero, or take a slide-rack hit. Suppressor-height tritium sights (like AmeriGlo 7XL) give you a backup sighting system that co-witnesses through the RDS window.
How do I know which mounting plate to order?
For Glock MOS pistols, the 407C uses the #04 plate that ships with new Glock MOS pistols. For SIG P320 X-series, S&W M&P CORE, and others, the RMR-cut plate from the factory will work. If you're unsure, search "[your pistol] RMR plate" — that's the one you need.
What's the warranty?
Holosun backs the HE407C-GR X2 with their limited lifetime warranty against defects in materials and workmanship. Battery, lens cleaning consumables, and damage from drops or modifications excluded.
