Submachine Gun

Submachine Guns, also known as SMG's, are rapid-fire weapons. They tend to have high fire rates, low damage, small magazines, and quick reload times. Many of the SMGs in Borderlands are actually a separate class of weapon known as a 'Machine Pistol', but for all intents and purposes, they too are classed as SMGs. In form and function, an SMG can be thought of as the 'middle ground' between Pistols and Combat Rifles.

Fully automatic weapons of a small size. SMGs are categorized by their typically high firing rate, average accuracy (with exceptions in either direction) and quick reloading time. They do roughly the same amount of damage as auto Pistols per shot, and serve as the 'middle ground' between Pistols and Combat Rifles. Lilith can increase her effectiveness with this weapon type by equiping Mercenary class mods - these provide increased damage and regenerating ammunition with SMGs, among other things.

One series of SMGs, the Anarchy class (typically having the name Double Anarchy) fire four rounds per shot essentially turning an SMG into a highspeed shotgun. The reduced accuracy is offset by incredible damage / critical damage potential when used at point blank range. While Dahl and Tediore are almost always the manufacturer of these series of SMGs, it has been rumored that other manufacturers make these series, but are rare.

Another series of SMGs are the Thumper SMGs, which typically have a slow fire rate and increased damage. They are also more acurate than normal SMGs.
