The SIG P365 is primarily cut for the SIG Sauer RomeoZero optic. This compact red dot sight is designed to match the P365's slim profile, providing a perfect fit that maintains the handgun's concealability and handling.

Yes, you can add a red dot to your SIG P365. The P365 models come with or can be modified to include a slide that is cut for optics, allowing for the easy installation of compatible red dot sights such as the SIG Sauer RomeoZero, Holosun HS507K, or Trijicon RMRcc.

  3. Finally, reassemble your firearm and perform a function check to ensure everything is properly installed.

If your P365 doesn't feature an optic-ready slide, then get yourself a P365 mounting plate onto which you can install your P365 red dot following the steps above.
