Holosun lists a green option for each (HE407C-X2-GR with a 2 MOA green dot; HE507C-X2-GR with a green MRS). Holosun’s page prices are not our MSRP data and can change; we have not tracked either.

The one real difference: the reticle

Holosun’s 407C X2 page lists a single “2 MOA Dot” and “Selectable Reticle: No.” The 507C X2 page lists “2 MOA Dot & 32 MOA Circle” and “Selectable Reticle: Yes,” and its feature list describes a selectable 2 MOA dot, 32 MOA circle, or circle-dot combination. On the printed tables the price gap on those two pages was $76.47.

What matches on paper

Window, body size, weight, battery, runtime, brightness steps, travel, water and vibration ratings are identical in Holosun’s tables, and both mount directly to the RMR footprint. So a holster or slide cut for one should take the other; confirm with your holster or slide maker.

Holosun prints “Automatic Brightness: No” for both X2 models and 50,000 hours at setting 6. Our X3 comparison covers the newer pair and what Holosun lists there.

Which to pick (on paper)

One dot and the lower printed price: the HS407C-X2.
A circle option on the same body: the HS507C-X2, which can also be set to the dot alone according to Holosun’s reticle list.

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