This is for a sig Legion P220 SAO. I was told to mention in the notes to state that it is the SAO version to ensure the safety fits form whoever runs your Instagram.

To clarify, this is for an XDM 10mm in 4.5" barrel. I have my CMF-208 mounted as far back as it will mount, which is about flush with the front of the slide. The light seems to angle a little bit upward when tightened down, so hopefully you've molded your holster exactly to this weapon.
