About this opticPolymer housing — light, and not a duty optic.

Same slides, different optics

14 other optics on the Shield RMSc footprint go on the same slides as the SIG Sauer ROMEOZero, so the table below answers for them too. What tells them apart:

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: normally a lower-third co-witness on a direct cut. Mounted directly, the optic sits as low as the cut allows, the best case for a co-witness. 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.

Sight heights published for this optic on 1 slide

GLOCK 17 / 19 / 34 Gen4 MOS

Dawson Precision · co-witness · front .415 / rear .420 in

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.

Shield RMSc footprintThe most common cut on carry-size pistols. Whether a Holosun K optic goes straight on depends on the slide, not the footprint: a K optic has recesses for the two front lugs only, so it drops onto an RMSc cut with no rear lugs, but a cut that has all four (the original GLOCK Slimline MOS) needs a plate. Each pistol's page says which it is.
