NOTE:
OPF-P365 Macro, RMRcc will NOT work with an RMR.
OPF-P365 Macro, RMRcc will ship with both M3 0.5 x 10mm, and M3 0.5 x 12mm plate to slide screws. Recent samples had shown some P365s may have shorter screw holes than previous versions. If 12mm screws are too long, use the 10mm screws for plate to slide.
OPF-P365 Macro, RMRcc is compatible with P365 Macro, or the new (October, 2022) version of P365X that has the rear sight in its own dovetail, as shown below.
It is NOT compatible with the SIG P365 Fuse that uses yet another (3rd variation for P365) footprint that doesn't have the M3 threaded posts, but uses M4 threads.
OPF-P320 Macro, RMRcc can be used on older P365X where the optics plate and rear sight are integrated: Installing the P365X Macro RMRcc plate will not allow the installation of a rear sight.
Given's SIG's penchant for changing things with abandon and no apparent reasons, here's one thing to look out for on your slide.
Please remove the slide's optics cut cover plate, and ensure the slot is present. OPF-P365X, RMRcc has an oval shaped indexer that mates with the slot on the slide, but some P365X slides do not have this feature.
Your slide must have the slot in the center as shown below:
If the slide does not have the center slot as shown below, OPF-P365X, RMRcc will need to have the oval shaped indexer removed in order to fully seat in the pocket.
