Ask the owner. Or, if the gun was left here by someone else—[ Because she has three of her father's pistols tucked away in her room. ]—probably just best to ask someone who knows. That's for Earth weapons.

[ She moves down a bit, to a set of guns that are similar, but not quite the same as the ones she just showed him. ] These are the ones that came on the Tranquility. These have standard ammo, which will fit in any type of gun. So if it looks like this? It'll use the same type of ammunition. The handguns probably use fifty caliber, the rifles a twenty-two, but it'd be best to ask Jax or someone who works in Gunnery about that, since I'm not sure. I don't really use them, I just know a lot since my dad sold weapons for a living back home.
