Below are the best Red & Green dot optics for your Sig Sauer P365X, 365XL, 365X-Macro, P365-380, or Sig P365 9mm CA Edition. These will fit directly on your slide with no modification. Here is an install video on the P322 but the process would be similar for your pistol.

Note* If you have a Sig P365 FUSE you will need these screws to mount an EPS Carry
