Adapter plates for the GLOCK 48 MOS
| Plate | Gives you | Source | Price |
|---|---|---|---|
| V4 MIL/LEO 43X / 48 MOS → Holosun 407K / 507KC&H lists it for the 407K and 507K, and for the G43X MOS and G48 MOS. Plate-to-slide screws (M4 x 10.5 mm) come with it; the optic's own screws are not in the listing. | Holosun K | C&H Precision ↗ | $25–60 |
| V4 MIL/LEO 43X / 48 MOS → Holosun EPS / EPS Carry / SCS CarryA separate plate from C&H's 407K / 507K one. C&H's list names the EPS and EPS Carry, and its title adds the SCS Carry. Plate-to-slide screws (M4 x 10 mm) come with it. | Holosun K | C&H Precision ↗ | $25–60 |
| RMRcc mount plate for GLOCK 43X / 48 MOS (AC32126)Trijicon's own plate, for the RMRcc. Trijicon says it is not compatible with the new Glock 48 MOS Gen 6. Its page lists two screws and a hex key with it. | Trijicon RMRcc | Trijicon ↗ | $60–95 |
| V4 MIL/LEO 43X / 48 MOS → Trijicon RMRccC&H lists it for the G43X, G43X MOS and G48 MOS, and for the Trijicon RMRcc only. Plate and optic screws come with it, and C&H says the RMRcc sits higher on it than other optics do and needs the sealing plate to stay waterproof. | Trijicon RMRcc | C&H Precision ↗ | $25–60 |
| V4 MIL/LEO 43X / 48 MOS → Trijicon RMR / SRO / Holosun 407C / 507C / 508TC&H lists it for the G43X, G43X MOS and G48 MOS, and for the RMR, SRO, Holosun 407C, 507C, 507Comp and 508T, its own EDC-XL and Comp, and the Olight Osight X. Plate screws (M4 x 8 mm) and a set of 4-40 optic screws for each optic come with it; its screw set names the RMR HD too. It says the sealing plate is needed to stay waterproof. | Trijicon RMR | C&H Precision ↗ | $25–60 |
| V4 MIL/LEO 43X / 48 MOS → Trijicon RMR / SRO / Holosun 407C / 507C / 508T (steel)The mild-steel version of C&H's RMR plate, listed for the same G43X, G43X MOS and G48 MOS and the same optics. M4 x 8 mm plate screws and 6-32 optic screws come with it, not the aluminium plate's 4-40 ones. | Trijicon RMR | C&H Precision ↗ | $60–95 |

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.
