Smith & Wesson M&P (Stainless Slide)
In Season 5, Sarah appears to change over to a stainless slide Smith & Wesson M&P as her main sidearm instead of the 5906 which is evident by the slide profile. In "Chuck Versus the Bearded Bandit" (S5E02), she draws it during the rescue mission. She also is seen with it in "Chuck Versus the Frosted Tips" (S5E03).
In Season 5's "Chuck Versus the Frosted Tips" (S5E03), Casey (Adam Baldwin) contemplates whether to take his SIG or a 4" Smith & Wesson Model 500 to the shooting range.

Other
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.

"Castle" was the code name for the underground CIA/NSA substation where Sarah, Casey, Chuck, and Morgan communicate with their superiors (mainly General Diane Beckman).

Sarah mentions that they now have Cruise missiles, and two private jets.
