Will this fit my sig Sauer m17 that is not optics ready?

Expert Answer

A

Answered by Ethan, Gear Expert, from IL, United States, on August 11, 2025

The P320 M17 only comes optic ready. If your pistol is not optic ready then you have a standard P320, or a non-M17 slide that isn't optic ready. Either way you cannot use this adapter. Please email us at Techsales@opticsplanet.com for assistance.
