The PTR Industries Vent4 is a suppressor rated for .45 caliber and built from titanium, a material chosen when a can needs to stay light on the muzzle. A .45 caliber rating suits big-bore pistol and carbine hosts, where subsonic loads pair naturally with a suppressor.
The Vent4 joins PTR's titanium Vent line of suppressors. It is a regulated NFA item, so it transfers through a licensed dealer on an ATF Form 4 with the federal tax stamp before it goes home.
