What pistols fit the Holosun SCS MOS?

Page last updated October 1, 2026. Data compiled September 2026 by Andrew Terrebonne.

It uses the Holosun SCS (MOS) footprint and mounts to 16 of the 178 slides tracked here, 16 of them with no adapter plate. An enclosed-emitter optic: 1.3 oz, a Solar + internal cell battery, with a 2 MOA + 32 MOA circle reticle.

About this opticBolts to the MOS pocket with no plate. GLOCK MOS only.

Sight co-witness, where no sight maker publishes heightsDepends on your front sight height, which can vary by SKU and production run within one model. Standard-height irons: no co-witness. Suppressor-height irons: low in the window at best, since enclosed emitters sit tall. Mounted directly, the optic sits as low as the cut allows, but an enclosed housing gives most of that height back. That's the typical case for this kind of optic, not a guarantee: pistols don't standardize sight and optic heights the way rifles do. Where one does, its figures are below and take precedence.

Heights are front / rear in inches, as each sight maker measures its own sights. That's not a deck height, and it doesn't compare across makers to the thousandth. Absolute puts the front sight level with the dot; lower 1/3 and lower 1/5 sit it lower in the window. A sight maker sells a handful of fixed heights, so optics of similar height share one set: the same figures under two optics are the maker's chart saying so, not a copy.

Cost to mount is the optic plus the cheapest plate that fits, in approximate street-price bands from September 2026, for comparing routes. Pistols aren't priced, so when slides tie, the card names the most popular one.
