Uzis
From WikiRaider
The Uzis can be found in every Tomb Raider from 1 to Chronicles. Each shot is only slightly stronger than the Pistols, but it shoots MUCH faster. From Tomb Raider 3 onwards ammo tends to be rare, greatly decreasing its usefulness. In Tomb Raider 1 and 2 however it is arguably the most potent all-round weapon.
