Toy dart guns having double action trigger assemblies and toy darts for use with the same

A toy dart gun is provided including a gun shell, a trigger assembly, and a compression assembly. The trigger assembly includes a swing arm coupled to the gun shell and movable between a safe position and a fire position, and a swing arm pusher extending from the gun shell and having an inclined surface. The compression assembly includes a compression chamber positioned within the gun shell and having a barrel opening and an opposite holder opening, and a plunger slidably insertable through the holder opening and movable between a retracted position and an extended position. As the swing arm moves toward the fire position, the swing arm engages the plunger and pulls the plunger toward the extended position. When the swing arm is in the fire position, the swing arm pusher deflects the swing arm from engagement with the plunger and the plunger is biased toward the retracted position.
