If you are looking for red or green dot sights that will fit on your Sig P320 or Sig M17/M18 without the need for extra adapter or filler plates then keep scrolling. *Note your slide must be optics ready and must have a Romeo 1 Pro Cut!

The optics listed below all come with a DeltaPoint Pro footprint and will fit any Sig P320, M17, or M18 with a Romeo 1 Pro slide.

You can identify your Romeo 1 Pro slide by making sure you have a curved front part of the slide cut out.
