How do you get 2 pistols on Tomb Raider 6?

You can't have two pistols in Tomb Raider 6 (Tomb Raider: Legend). The game doesn't allow Lara to dual-wield any weapons, including pistols.

She can carry a variety of weapons, including pistols, shotguns, machine guns, and even explosives, but she can only use one at a time.
