What firing mechanism does a DFSG use?

• A. Spring-loaded hammer mechanism
• B. Mechanical trigger with laser actuating a gas cartridge
• C. Electric spark gap only
• D. Compressed gas firing system or BB gun style

Answer: (D)

The firing mechanism works by propelling a dart with stored gas, not by a purely mechanical hammer or by an electric discharge alone. In a DFSG, compressed gas (like CO2 or compressed air) is released when the trigger is pulled, pushing the dart out of the barrel much like a BB gun or airgun. The device’s electrical stun system is separate and activates when the dart makes contact, delivering the stun through the tethered wires. A spring-loaded hammer relies on mechanical energy to drive a projectile, which isn’t how this design launches its darts, and a purely electric spark-gap setup wouldn’t project a dart at all. Lasers aren’t used to actuate the gas in this mechanism.
