By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

Two enclosed-emitter pistol dots from the same Holosun series. The full-size EPS is sold for a duty-style handgun footprint; the EPS Carry is the smaller body for subcompact and slimline pistols. Both list a K footprint. We compare the 2 MOA red-dot SKU of each: EPS-RD-2 and EPS-CARRY-RD-2. Every figure is from Holosun’s product pages, checked November 5, 2026.

Same footprint name, different adapter: Holosun lists the K footprint as the direct mount on both, then ships an RMR-to-K plate with the EPS and an RMSc-to-K plate with the EPS Carry. Check your slide’s cut against Holosun’s fitment list before you buy. We list no price: Holosun prints one on each page, but street prices move.

Which to pick (on paper)

If window size is the deciding number: the EPS. Holosun lists 0.90″ × 0.63″ against 0.77″ × 0.58″ on the EPS Carry.
If weight and body size matter on a slim carry gun: the EPS Carry. Holosun lists 1.23 oz and a 1.07″ by 0.95″ body width and height, against 1.4 oz and 1.19″ by 0.99″ for the EPS.
If your slide is cut for RMSc: the EPS Carry is the one Holosun ships with an RMSc-to-K plate. The EPS ships with an RMR-to-K plate.
If you want a battery you can swap without dismounting: both list a CR1620 in a side tray.

We have not range-tested these; facts above are from Holosun’s pages.
