Same slides, different optics

6 other optics on the Holosun K footprint go on the same slides as the Holosun 407K X2, so the table below answers for them too. What tells them apart:

All 7 Holosun K optics

Sight co-witnessDepends 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. This optic's window runs small (19.6 × 14.7 mm), so a front sight slightly off the ideal height is more likely to miss it. 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.

Holosun K footprintRMSc screw spacing with the two rear recoil lugs left off. So a K optic fits an RMSc cut only where that cut has no rear lugs; on a four-lug cut such as the original GLOCK Slimline MOS it needs a plate. Whether an RMSc-pattern optic goes on a K cut the other way round is up to each slide's maker; each pistol's page says what that maker lists. Holosun packs different screw pairs with different K models, so check what came in the box.
