Description
This M17 4.7″ Coyote Tan Slide Assembly allows P320 FULL-SIZE owners to easily swap their existing slide configuration for this world-renowned slide and optic assembly. Easily equip your P320 with the factory-mounted, American-built ROMEO-M17 featuring SIG SAUER’s proprietary SIG-LOC mounting system.
The ROMEO-M17 boasts a fully enclosed, sealed, and purged optical system for ultimate protection against all elements. Its low deck height allows for absolute co-witness with the existing standard-height sights.
