That's some pistol.
Or a tiny caliber.
Reminds me of this apocryphal story I heard in the army (but it sure rings true). It works best when you imagine the corporal speaking wiff a heavy Afrikaans eksint:
The new recruits are learning navigation skills. "Right," says the corporal. "You have a circle!" And he draws a little circle on the board. "180 degrees in a circle!" And he starts talking about angles and compasses and things. After a while one of the brighter recruits puts up a hand and asks: "But corporal, doesn't a circle have 360 degrees?"
The corporal does a double take, looking at the circle he drew. "No!" he barks. "It's a SMALL circle!"
