This minigun is held in a single hand by a forward mounted pistol grip supported aft by a gauntlet similar to the way the T-600 handles the minigun in Terminator Salvation.

Other
Opening Credits Pistol
A pistol is seen in silhouette during the opening credits of each episode of Chuck. This pistol appears to be an amalgamation of a Beretta and a Jericho 941.
Tranquilizer Baby WE Hi-Capa 3.8 (Type 8)
The "Trank Gun" frequently seen used by Chuck in the series is an airsoft handgun known as the Baby Hi-Capa 3.8. The airsoft pistol is customized to fire tranquilizer darts with the standard "Green Gas" rather than airsoft pellets. It is also customized with an extended barrel due to painting over the orange tip (required by US law), with metallic silver paint. A red or green laser sometimes accompanies the gun on it's bottom accessory rack. The ammunition is varied, but most commonly used are the "10mg Darts". The darts can also be stuck manually into someone to gain the same effect. It has been referred to several times that the medication in the darts is a diluted Tetradotoxin (Anhydrotetrodotoxin) solution. There is another kind of dart that has a fast-acting small dose of Ketamine. The vents on the slide indicate that it is a Type 8. Because of Chuck's distaste for real weapons, the team begins to use the trank guns much more often beginning in Season 4, especially on kidnapping missions. The trank guns are often used on unarmed/unsuspecting persons instead of more lethal weapons.
