Holosun has labeled the EPS Core line new for 2026, pairing an enclosed emitter and RMSc mounting footprint with what the company calls a full-size EPS viewing window. The current official pages cover red and green 3 MOA dot models plus red, green, and gold multi-reticle models. All five share a 0.9 by 0.63-inch window, 1.61 by 1.18 by 0.97-inch body, 1.4-ounce listed weight, and direct RMSc fitment. Holosun positions the series for slim and subcompact pistol slides, but compatibility still depends on the individual slide cut and hardware.

Two reticle packages

The 3 MOA models offer a single dot. Holosun lists the red EPS-CORE-RD-3 at $270.58 and the green EPS-CORE-GR-3 at $282.34. Both use a forward-facing light sensor, Shake Awake, automatic shutoff, memory, manual controls, and lockout mode. Their pages list eight daylight settings and four night-vision settings. They do not include Solar Failsafe or selectable reticles, making them the simpler and less expensive options among the five published configurations.

The MRS versions allow selection among a 2 MOA dot, a 32 MOA circle, and a combined circle-dot. Holosun lists red and gold MRS models at $329.40 and the green version at $352.93. Those three add Solar Failsafe while retaining a forward sensor, Shake Awake, automatic shutoff, memory, manual brightness, and lockout. The pages describe supplemental solar power and changing-light support, although their detailed function tables separately mark automatic brightness as “No.” Buyers should treat that inconsistency as unresolved until Holosun clarifies exactly how the sensor and control modes operate.
