This is a secondary weapon but don't be fooled. It can mow through Gunners and Ghouls with ease. The gun spits out .38 caliber ammo.
Like the rifles, the OTs-33 comes with custom sounds, animations and some optional modifications if you want to switch things up a little bit.
This pistol is a little easier to find. It'll spawn at traders, on legendary enemies, or on characters of the Gunner variety.
