Glock 34 Gen5 MOS optic footprint: what red dots fit

Glock 34 Gen5 MOS

Competition shooters ask this one constantly: the Glock 34 Gen5 MOS is not cut for a footprint, it is cut for Glock's MOS plate system. The 5.31-inch Gen5 slide carries the MOS pocket, the plate bolts into the pocket, and the optic bolts to the plate. Plate 02 in the factory set serves the Trijicon RMR and Holosun 507C family and Plate 04 serves the Leupold DeltaPoint Pro; aftermarket plates add Aimpoint ACRO, Holosun 509T, Holosun EPS, and Shield RMSc / Holosun K. Every large-window Carry Optics dot reaches this slide through one of those plates.

The Glock 34 MOS is the Carry Optics build host, and plate choice matters more here than on a carry gun because the mount sees a full season of round count. A machined steel or aluminum plate is the usual competition answer for that reason. The 5.31-inch slide also leaves room for the large-window optics competition shooters favor, which the shorter Glock slides do not.

Glock 34 Gen5 MOS optic fitment FAQ

What optic footprint does the Glock 34 Gen5 MOS use?

Competition shooters ask this one constantly: the Glock 34 Gen5 MOS is not cut for a footprint, it is cut for Glock's MOS plate system. The 5.31-inch Gen5 slide carries the MOS pocket, the plate bolts into the pocket, and the optic bolts to the plate. Plate 02 in the factory set serves the Trijicon RMR and Holosun 507C family and Plate 04 serves the Leupold DeltaPoint Pro; aftermarket plates add Aimpoint ACRO, Holosun 509T, Holosun EPS, and Shield RMSc / Holosun K. Every large-window Carry Optics dot reaches this slide through one of those plates.

Do I need an adapter plate to mount a red dot on the Glock 34 Gen5 MOS?

Yes, for almost every optic. The Glock 34 Gen5 MOS mounts red dots through a plate system, so you bolt the plate matching your optic's footprint into the slide and then bolt the optic to the plate. The exceptions are optics built for that pocket, such as the C&H Direct Mount Optic for Glock MOS and Holosun SCS-MOS, which mount with no plate. Plates are available for the Trijicon RMR / Holosun 507C, Shield RMSc / Holosun K, Leupold DeltaPoint Pro, Aimpoint ACRO, Holosun 509T and Holosun EPS footprints.

Does the Holosun 507C X2 fit a Glock 34 Gen5 MOS?

Yes, on a plate. The Holosun 507C X2 is a Trijicon RMR / Holosun 507C footprint optic, so it mounts on the Glock 34 Gen5 MOS using a matching plate such as the Glock OEM MOS Adapter Plate 02 RMR and C&H Precision Glock MOS to RMR Steel Adapter Plate. Install the plate to the slide first, then the optic to the plate.

Does the Trijicon RMR Type 2 fit a Glock 34 Gen5 MOS?

Yes, on a plate. The Trijicon RMR Type 2 is a Trijicon RMR / Holosun 507C footprint optic, so it mounts on the Glock 34 Gen5 MOS using a matching plate such as the Glock OEM MOS Adapter Plate 02 RMR and C&H Precision Glock MOS to RMR Steel Adapter Plate. Install the plate to the slide first, then the optic to the plate.

Does the Holosun 507K X2 fit a Glock 34 Gen5 MOS?

Yes, on a plate. The Holosun 507K X2 is a Shield RMSc / Holosun K footprint optic, so it mounts on the Glock 34 Gen5 MOS using a matching plate such as the C&H Precision Glock MOS RMSc / Holosun K Steel Plate and Calculated Kinetics Glock MOS DOGTAG RMSc / K Plate. Install the plate to the slide first, then the optic to the plate.

Does the Holosun EPS Carry fit a Glock 34 Gen5 MOS?

Yes, on a plate. The Holosun EPS Carry mounts on the Glock 34 Gen5 MOS using a matching plate such as the C&H Precision Glock MOS RMSc / Holosun K Steel Plate and Calculated Kinetics Glock MOS DOGTAG EPS Plate. Install the plate to the slide first, then the optic to the plate.

Does a Glock 19 MOS plate fit a Glock 34 MOS?

Yes. All the Gen5 MOS slides share one pocket, so a Glock MOS plate fits the 34 the same as the 17, 19, and 45. Only the Gen6 ORS plates are a separate family.
