Steiner MPS 2.0 vs Holosun EPS-RD-2

Two enclosed-emitter pistol red dots on different footprints: the Steiner MPS 2.0 mounts on the Aimpoint ACRO pattern, the Holosun EPS-RD-2 on Holosun’s K footprint. A pistol cut for one will not take the other without an adapter or a different slide. Figures come from each maker’s own product page, read on November 5, 2026. We use the current MPS 2.0, not the original MPS Micro.

  Holosun EPS-RD-2

Steiner’s page spells the sixth brightness line as “6 day/night modes; 2x NV compatible modes”; we quote it as printed. No prices are in this table.

What differs on paper

• Footprint: ACRO versus K. This is the deciding fact for most buyers, because it follows the slide cut on your pistol.
• Weight: 2.32 oz for the MPS 2.0 against 1.4 oz for the EPS-RD-2, as printed.
• Battery: CR2032 against CR1620. Steiner prints up to 90,000 hours (at level 4); Holosun prints 50,000 hours (at setting 6). The settings differ, so the two runtimes are not exactly like-for-like.
• Dot size: Steiner sells 2 MOA and 3.3 MOA versions; Holosun lists a 2 MOA dot.
• Adjustment: 1 MOA per click on the Steiner; 1.5 MOA per click on the Holosun.

Which to pick (on paper)

• A pistol already cut for ACRO, or a longer printed runtime: the MPS 2.0.
• A pistol cut for the K footprint, or the lighter body: the EPS-RD-2.

We have not range-tested either; every figure is quoted from the maker’s page.
