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.

FAQ

Does it need an FFL?

No. This is not the serialized part, so it ships directly to you where legal. Check your state and local laws.
