A device capable of firing a projectile at high velocity, yes.
It's interesting, but little is known at this point.
Two shots or one?
What manner of round/s?
Was a single projectile deflected off the director and into the DP, or some other order of events/number of shots?
There's speculation that the propmaster's daughter took the gun for target practice & left a highly lethal round or rounds (non-blank) in the device, and that it was then given to Baldwin unchecked.
Or what indeed - much unknown!
