The air pistol STI Duty One is a faithful replica of the original live-fire version with all details including a functional safety. ASG manufactures this model under a purchased licence. The polymer frame of the pistol is complemented by a metal slide with a functional slide stop. A manual safety is used to secure the pistol against unintentional discharge. The magazine with a return spring has a capacity of 20 BB pellets.
The pistol is powered by a 12 g CO2 cartridge that is inserted directly into the grip. After insertion, the cartridge must be tightened with a screw. The internal barrel thread allows a sound moderator to be screwed onto the pistol.
