How to read this chart

Each row is something a maker wrote on its own page, in quotation marks, with a link. We list only maker-stated pairings. We do not infer that an optic fits a pistol from similar footprint names, so check the maker’s page before you buy. Methods: How we track, editorial standards and corrections.

Red dots: what each maker states

Red dot optics and the footprint or mount each maker states, quoted exactly.
Optic	What the maker states	Source
Trijicon SRO	“Identical Footprint as RMR”	Maker page
Trijicon RMR Type 2 (RM06)	“The RMR Type 2 has identical physical dimensions and mounting footprint to that of the original RMR Type 1.

Note: If you are installing the DeltaPoint Pro on a milled slide, or Glock MOS the mount base & dovetail are not required.”	Maker page

Pistols: what each maker states

Glock MOS, Gen6 and Slimline plates

Glock’s optic mounting page, checked Nov 4, 2026, lists the plate for each optic on standard-frame Gen6 pistols: the 02 Plate for the Trijicon RMR, RCR, RMR HD and SRO, Holosun 508T, 407C and 507C/Comp, and C&H Precision; the 03 Plate for C-More Optics; and the 04 Plate for the Vortex Defender-ST/XL, EOTech EFLX and Leupold DPP. Glock says Slimline MOS models “do not need Adapter Plates,” and the MOS-K cut takes M3 screws “provided by optics manufacturers.” You can tell the cuts apart from the item number on the case: MOS-K models include “MOSK” near the end.

Not yet verified

Glock’s page does not say which plate a Gen4 or Gen5 MOS pistol needs for a given optic beyond the single included plate quoted above, so we do not list one. Trijicon separately states, in the RMR row above, that an RMR needs mounting kit AC32064 on the Glock MOS.

Frequently asked questions

Does the RMR Type 2 use the same footprint as the original RMR?

Trijicon says: "The RMR Type 2 has identical physical dimensions and mounting footprint to that of the original RMR Type 1."

Does an RMR fit a Glock MOS slide directly?

Trijicon's RMR Type 2 page says a mounting kit is required: "If selecting an RMR for mounting on the Glock MOS, Springfield OSP, Walther PDP, or H&K VP9 Optics Ready, a Trijicon RMR mounting kit (AC32064) is required." Glock says its standard MOS models come with a single adapter plate that fits "Trijicon®, Ameriglo®, and Holosun® (except 509)," and lists the 02 Plate for the RMR on Gen6 pistols.

What footprint does the Glock 43X MOS use?

Glock states: "The standard SLIMLINE MOS cut fits the Shield RMSc footprint and uses M4 screws." MOS-K models accept "either Holosun K or RMSc footprints."

What footprint does the SIG P365X use?

SIG states: "RX Footprint: COMPACT (Shield RMSc); slide cut to accommodate a direct fit with the ROMEO-X COMPACT".

What is the Holosun K footprint?

We do not define it. Holosun states "Designed around the Holosun K footprint; Fitment: Direct Mount K Footprint" for the HS507K X2 and "Fitment: Direct Mount Holosun K Footprint" for the HS407K X2.
