Holosun EPS-CORE-RD-3 is an enclosed pistol red dot with a single, clean 3 MOA dot on the full-size EPS lens and a compact Shield RMSc footprint. It is the simplest member of the EPS Core range: one reticle, one job, done fast.

A 3 MOA dot you pick up instantly

The 3 MOA dot is the middle ground most carry shooters end up choosing. It is large enough to find quickly on the draw and under recoil, yet still fine enough to hold a defensive-distance group.

Full-size EPS window on a slim-slide footprint

The EPS Core uses the large EPS lens, which gives a noticeably wider sight picture than a typical micro optic, while the Shield RMSc footprint still lets it mount directly on many slim and subcompact slides without an adapter plate.

Enclosed emitter, sealed against the weather

The sealed emitter housing keeps dust, debris and moisture off the LED. That is the practical reason enclosed optics stay usable in rain, snow and daily concealed carry, where an open emitter can get blocked.

Automatic brightness that keeps up with the light

A forward-facing light sensor matches the reticle to ambient light as you move between indoors and bright sun. Manual brightness with memory recall and Lockout Mode are there when you would rather set it yourself.

Always ready, always efficient

Shake Awake powers the optic up the moment it senses movement and shuts it down when idle. With up to 50,000 hours on a CR1620, it stays ready without routine maintenance.

Battery change without losing zero

The side-loading battery tray lets you swap the CR1620 without taking the optic off the slide, so your zero stays where you left it.
