No, the SIG SAUER ROMEOZero-R Red Dot Sight uses the Trijicon RMR footprint. The P365 X-Macro is designed to accept optics with the RMSc footprint. Some direct fit options include the Sig Romeo Zero, Shield RMSc, Vortex Defender CCW, Holosun 407K/507K and more.
The SIG SAUER ROMEOZero-R Red Dot Sight will be compatible with your P229 Pro-Cut slide assembly. However, since this optic uses the RMR footprint, you will need to use a sealing plate in order to properly install the optic. Optics that use the Deltapoint Pro footprint such as the Sig Romeo 1 Pro, Eotech EFLX, and Leupold Deltapoint Pro would not require the use of a sealing plate.
The SIG SAUER ROMEOZero-R Red Dot Sight uses the Trijicon RMR footprint and will be compatible with the 509 Tactical via the #2 MRD optic plate included with your FN.
The SIG SAUER ROMEOZero-R Red Dot Sight features a motion activated auto-on feature that turns the optic on every time it detects movement.
The SIG SAUER ROMEOZero-R Red Dot Sight uses the RMR footprint. In order to mount it to a Canik TP9 Elite Combat you will need a compatible adapter plate since the optics cut on that gun fits the Vortex Venom Footprint. Canik does not state the height of the front sight and depending on the adapter plate you use the alignment of the rear sight on the SIG SAUER ROMEOZero-R Red Dot Sight and the front sight cannot be guaranteed.
