The Uzi being used on a Target Dummy

The Uzi is a Hardmode gun that fires bullets at high velocity, with a high rate of fire, and with high damage output. Musket Balls and Silver/Tungsten Bullets shot from this weapon gain the effects (but not damage) of High Velocity Bullets. The Uzi has a 1* 1/100 (1%) / 0.5* 1/200 (0.5%) chance to drop from an Angry Trapper.

Its best modifier is Unreal.

The Venus Magnum can be considered a direct upgrade of the Uzi, as it boasts minor improvements to almost all stats. However, only the 3DS version has the auto-fire feature of the Uzi, which can make it physically tiring to use.

The Uzi can be considered an alternative to the Megashark, if the player is fortunate enough to have an Angry Trapper drop it. The main differences are: The Uzi is obtainable before defeating any Hardmode bosses, while the Megashark requires The Destroyer to be defeated first. The Uzi has a 172.232% higher base knockback/second than the Megashark (23.333 versus 8.571). The Uzi is slightly slower but deals more damage per round. On enemies with more than 36 defense, the Uzi deals more damage per second using Crystal Bullets than a Megashark using the same. The Uzi lacks the Megashark's ammo conservation feature, which can easily be compensated for with an Endless Musket Pouch High Velocity Bullets. The Uzi compared to the Megashark is fairly inaccurate, with up to 15° of bullet spread.
