Forward Controls Design OPF-P365 Macro Optic Plate – SIG P365 Macro, RMRcc

A steel optic plate that mounts a Trijicon RMRcc on the SIG Sauer P365 Macro and on P365X slides with the rear sight in its own dovetail.

The OPF-P365 Macro, RMRcc gives the RMRcc a flat mounting surface on P365 slides that use M3 threaded posts in the optic pocket. This version has no rear sight dovetail. It is machined in 4140 steel and black oxide coated; it is not nitrided because nitriding would make the thin plate extension over the slide brittle.

Key features

• 4140 steel — Machined in 4140 steel with a black oxide finish.
• Oval indexer — An indexer under the plate mates with the slot in the slide's optic pocket.
• Screws for current slides — Supplied with M3-0.5 × 8 mm plate-to-slide screws, as screw hole depth on P365 slides has varied between production years.

Compatibility and fitment

• Pistols: SIG Sauer P365 Macro, and the newer (from October 2022) P365X that has the rear sight in its own dovetail on the slide.
• Not compatible with the SIG-LOC footprint — the P365 Fuse and the latest P365X slides, which have M4 tapped holes in the pocket instead of M3 threaded posts. Remove the cover plate and check the footprint before ordering.
• It can be used on older P365X slides where the optic plate and rear sight are integrated, but no rear sight can then be fitted, as the plate has no rear sight dovetail.
• It also fits the special-run FDE Glock 43X, where it sits 0.035 in taller.
• Sights: Trijicon RMRcc. It will not work with an RMR.
• The RMRcc sealing plate is required; it is supplied with the RMRcc by Trijicon.
• Remove the slide's optic cover plate and check that the slot in the centre of the pocket is present: the plate has an oval indexer that mates with it. Some slides lack the slot, and on those the indexer has to be removed from the plate before it will seat fully.
• Backup sights: with Night Fision sights for SIG the irons are very low but usable, and the tritium dot is partly obscured.
