Beckett's backup gun, it's most notably seen when she hands it to Castle to defend himself from the "Tick, Tick, Tick..." & "Boom!" killer when they enter the warehouse he's hiding in. He uses it to shoot Kate's Glock 19 out of the killers hand. After wards Castle reveals that "he was aiming for his head"
Noteworthy is that his "Aiming for the head" remark is the third Firefly /Serenity reference in the series. The first two took place during the episode "Vampire Weekend" when Castle wore his Mal costume, and the second was a catalyzer sitting on his bookshelf. A catalyzer is required for any Firefly class ship to run, and was a large part of Out of Gas' story arc.
