Holosun · Enclosed Pistol Sight
The EPS Core (EPS-CORE-RD-3) puts a full-size EPS window on the slim K / RMSc footprint. You get the wide 0.9" × 0.63" viewport of the full-size EPS behind a crisp 3 MOA red dot, on the very same cut that takes an EPS Carry — with the solar panel and multi-reticle system left off to bring the price down.
Mounts on the same Holosun K / RMSc-pattern cut as the EPS and EPS Carry. If your slide already wears one of those, the Core drops straight on.
A 0.9" × 0.63" viewport — the same glass area as the full-size EPS — on a footprint slim pistols already accept.
The emitter and lens are sealed against lint, sweat, rain, and holster debris, so the dot does not wash out or disappear when the weather turns.
Fine enough to hold precision at distance, bold enough to find fast up close, with 8 daylight and 4 night-vision brightness settings.
The optic sleeps to save battery and wakes instantly on movement — up to 50,000 hours on a single side-loading CR1620.
Locks the brightness buttons so a holster draw or a pocket cannot change your setting.
Hard-anodized 6061 housing, IPX8 waterproof and rated to 5000G vibration, at 1.4 oz.
The EPS Core uses the Holosun K / RMSc pattern, so any of these in-house optic cut services will take it — and each one lets you add the optic to the order and have it mounted and sighted in before the slide ships back:
Any slide with a Holosun K / RMSc-pattern optic cut — the same cut that takes an EPS or EPS Carry. That includes the SIG P365, S&W Shield and Hellcat, Glock 43X/48, and CZ 75 / P-01 / SP-01 slides we cut in house.
The Core keeps the fully enclosed housing and the full-size EPS window, and drops the solar panel and the multi-reticle system. You get a single 3 MOA dot and a lower price, on the same footprint.
3 MOA is the middle ground — fine enough to hold precision at distance, still fast to find up close. The 6 MOA dots in the EPS line favor speed over precision.
The sealed emitter keeps sweat, lint, rain, and holster debris off the LED and lens, so the dot stays clear — a real reliability edge on a carry or duty gun.
A side-loading CR1620, up to 50,000 hours on setting 6, with Shake Awake so the optic sleeps between uses and wakes on movement.
Yes. Order it with one of our Holosun K / RMSc optic cut services and we mill the slide, mount the optic and sight it in before it ships back.
