**IMPORTANT: You must check the accompanying video to ensure your Sig P320 M17 has the same optic cut from Sig Sauer. 

This is an aluminum optic mount with stainless steel threads for the Sig Sauer P320 M17/M18 pistol or X5 LEGION. We have mounts specifically for:

BurrisFastfire Fastfire III
C-more RTS2/STS2
Holosun 407K/507K, Holosun 507c/508T and Holosun 509T
Sig Romeo 3 Max/XL and Romeo1/Romeo1 Pro
Trijicon RMR/SRO
Vortex Venom/Viper and Razor

The mount is specific to the optic. It uses the factory threaded holes to mount the plate to the slide.  New screws, hex wrenches and thread locker provided. 

The ACSS Vulcan 509T will hang off the end of the optic mount/slide, so we do not recommend using our 509T mount for it.
