Add a Holoson 509ACSS Optic Cut as a standalone upgrade to your Sig P320 slide.
The cut features a precision CNC machined pocket directly in front of the Sig factory rear sight dovetail. By design, the optic will fit tight within this pocket, preventing the sight from moving in any direction, ensuring your optic remains zeroed in even under the harshest conditions.
PLEASE NOTE: THIS OPTIC CUT IS NOT COMPATIBLE WITH THE REGULAR 509T.
THIS OPTIC CUT IS COMPATIBLE WITH SOLID SLIDE VARIANTS ONLY
