Glock standard width (G17/G19/G26) Chart

This page is a working reference for those who want to plan out their optic and sight options with our slides. Most of these optic cuts are available through our special order pages. The chart below summarizes most of the options we offer while addressing the following technical specifications:

  • What optic cut to use for a specific optic (Section A)
  • What the optic mount holes are tapped for (Section B)
  • Which sight options provide a lower 1/3rd co-witness or other notable setups (Section C)
  • Any notable information i.e. installation pitfalls, suggestions, special notes (Section D)

As always, feel free to reach out to info@norsso.com for any questions.
