The Holosun EPS CORE Gold Dot Sight (SKU EPS-CORE-GD-3) is a 1× enclosed emitter pistol gold dot sight running a fixed 3 MOA gold dot at 590nm on a direct RMSc footprint, in a Hard Anodized 6061 aluminium housing measuring 1.61 × 1.18 × 0.97 in (40.9 × 30.0 × 24.6 mm) and weighing 1.4 oz (40 g).
EPS CORE is the essentials-only version of the enclosed EPS: it drops Solar Failsafe and the premium housing alloy but keeps the sealed emitter that is the whole reason to buy one. The direct RMSc footprint mounts to slim-slide pistols with no adapter plate at all, and the side-loading CR1620 runs up to 50,000 hours with Shake Awake and brightness memory recall.
How it compares
Want switchable reticles instead of a fixed dot? The EPS CORE gold dot sight with Multi-Reticle System adds a 32 MOA circle. The same 3 MOA dot in red is the EPS CORE 3 MOA red dot sight, and in green the EPS CORE 3 MOA green dot sight. Stepping up, the EPS Carry 2 MOA gold dot sight adds a 7075-T6 housing and a K adapter plate. Browse all gold dot sights and every RMSc footprint optic we stock, or read the RMR versus RMSc footprint guide.
Ideal for
- Shooters with astigmatism who resolve a gold reticle more cleanly than red
- Airsoft gas blowback pistols where a sealed emitter beats an open one outdoors
- Section 1 long-barrelled pistols and licensed revolvers cut for RMSc, with no adapter needed
- Target and gallery rifle work wanting an all-round 3 MOA aiming point

Is the Holosun EPS CORE an RMSc or an RMR footprint optic?
The Holosun EPS CORE uses a direct RMSc footprint, so it mounts straight onto RMSc-cut slim-slide pistols with no adapter plate, and it is not an RMR-pattern optic. Our RMR versus RMSc footprint guide explains how to tell which cut your pistol has.
Will the EPS-CORE-GD-3 fit a Glock 43X, SIG P365 or Springfield Hellcat?
The EPS CORE uses the RMSc footprint, which is the pattern cut into slim-slide optics-ready pistols including the Glock 43X/48 MOS, the SIG Sauer P365 series and the Springfield Hellcat OSP. Slide cuts vary between production runs, so confirm your pistol's cut before ordering.
Why choose a 3 MOA dot on the Holosun EPS CORE?
A 3 MOA dot sits between the precise 2 MOA and the fast 6 MOA options, covering about 3 inches (roughly 87 mm) at 100 yards, which makes it a versatile all-round aiming point rather than a specialist one.
What battery does the Holosun EPS CORE use and how is it changed?
The EPS CORE takes a single CR1620 coin cell in a side-loading tray, so the battery can be replaced without removing the sight or losing your zero, and one cell gives up to 50,000 hours.
What is the difference between the EPS CORE and the EPS Carry?
The EPS CORE is the essentials-only model with a Hard Anodized 6061 aluminium housing and a direct RMSc footprint, while the EPS Carry uses a 7075-T6 housing and includes an RMSc-to-K adapter plate.
Does the Holosun EPS CORE have Solar Failsafe?
No — the EPS CORE runs on its CR1620 battery with Shake Awake motion activation. Solar Failsafe is fitted to the Multi-Reticle System versions of the EPS and EPS Carry instead.
