Holosun 407C X3 Red Dot – 2 MOA
The 407C X3 is the 2026 update to one of the most-mounted pistol optics on the market. Where the 507C gives you a switchable circle, the 407C keeps it to a single clean dot. Nothing to toggle, nothing to accidentally change under stress.
The red reticle is the traditional choice and the easiest on battery life. It sits cleanly against most backgrounds without the extra brightness that green demands. A 2 MOA dot is the precision choice. It covers two inches at 100 yards, so it doesn't hide a small target, and it's fine enough to shoot groups with rather than just point with.
The X3 generation brings a modernized 7075-T6 housing and a forward-facing light sensor that reads the light on your target. Solar Failsafe keeps the reticle alive off ambient light if the battery dies, and the side tray means a battery change doesn't cost you your zero. The RMR footprint fits the widest range of slides and adapter plates available.
