OPF-P365X, RMRcc is designed and made for SIG Sauer P365X/P365XL, and Trijicon's RMRcc. OPF-P365X, RMRcc rear sight dovetail is cut for popular Glock rear sights.

Machined in 4140 steel, and black oxide coated.  They don't black nitride OPF-P365X, RMRcc due to the thin plate extension over the slide, nitride would make it brittle.

SIG P365X and P365XL have a similar optics plate/rear sight design as the M17/M18, where the rear sight and optics plate are integrated, which means if the user removes the optics late, the rear sight is also removed, he can now use a red dot sight but without the rear sight.

Due to the design confines of the P365X, OPF-P365X, RMRcc has to be made rather tall, as it not only has to bring a flat mounting surface for the RMRcc, it also has to have adequate thickness for a rear sight dovetail.

BIS, P365X's front sight is 0.510 over the top of the P365X slide. 

For LE users whose agencies authorize P365X and RMRcc, and also mandates backup sights for red dot equipped handguns, OPF-P365X, RMRcc and BIX, P365X are designed and made for them.

Please NOTE:

• RMRcc sealing plate is required, a sealing plate comes with RMRcc.
• OPF-P365X, RMRcc is incompatible with P365 Macro, or the version of P365X that has the rear sight in its own dovetail.
• They will soon stop including the L keys with all OPF products, L keys will become optional, they strongly suggest a proper torque wrench to impart the correct torque value.
