Combat Armory CA19 | 9mm | 4.49″ Threaded | CA19PSTHR-RMR

The Combat Armory CA19 is a 9mm semi-automatic pistol built on a polymer frame with embedded stainless steel rails and a 4.49-inch threaded stainless steel barrel. The design accepts many Gen 3 OEM and aftermarket parts and features a medium-aggressive textured grip and an undercut trigger guard to aid ergonomics. For a practical optic under $1,000 that pairs well for sight acquisition and compactness, consider a Holosun 507K micro red dot, which complements the CA19’s intended use profile.

Applications for this pistol include everyday carry (where legal) and range training or competition shooting where a threaded barrel and optics-ready platform are desirable.
