Firing the .36

[Kristina77]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:
"So you shot one of them with a bullet before you remembered your tranquiliser gun?"
"I told Marty to use a silver gun"
Hugo sighs again. " Let me make a suggestion. Firing the .36 to make a noise would account for it being in his hand. Which, being a technique you are known to use, makes it the likeliest explanation, yes? "
