Q
Johnny boy, guest, from CA, United States, asked on July 30, 2023

Does this optic fit the California p320 m18?

Expert Answer
A
Answered by Kurt Colbourne, Gear Expert, from IL, United States, on June 14, 2024

No, this optic will only fit the SIG SAUER M17/M18 military issue and commemorative pistols with a single optics plate mounting screw. This is due to SIG SAUER'S proprietary SIG-LOC mounting interface, which the civilian P320-M17 & P320-M18 pistols do not have.

Q
RJ, member, from IN, United States, asked on January 23, 2025

Which optics would work best for my P320. I was going to purchase the M 17 but after reading it will not fit. So if someone could please advise!

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 24, 2025

The P320 comes from the factory with a Deltapoint Pro optic cut. This means you will be able to direct fit optics with the Deltapoint Pro, RMR, and K footprints. Direct fit options include the Sig Romeo 1 Pro, Leupold Deltapoint Pro, Vortex Defender ST and XL, Holosun EPS, Shield RMS and more.
