FAQ

What is the difference between a ported SIG P320 barrel and a threaded P320 barrel?

A ported P320 barrel uses openings machined directly into the barrel to vent gases through corresponding slide openings, while a threaded barrel is designed to accept compatible muzzle-mounted accessories. This Optimus barrel uses three integrated exhaust ports and does not rely on a threaded muzzle for its ported configuration.
