The B&T KH-9 Covert ships with one factory magazine (most commonly a 30-round magazine, though some packages list a 25-round), and is a closed-bolt, blowback, semi-automatic pistol with a DA/SA trigger and decocker. Its finish is black — hard-anodized aluminum on the upper with a polymer lower — and its typical magazine capacity is 30 rounds. The barrel does not use a conventional threaded muzzle; instead the Covert uses a tri-lug/quick-attach interface intended for suppressors and dedicated muzzle devices (adapters to standard threads are available separately if you require them).
