Ammu-Nation and Social Club description.

The Gusenberg Sweeper is a submachine gun (categorized as a light machine gun) that is available in Grand Theft Auto V, and was initially available in Grand Theft Auto Online as a time-restricted weapon from February 13 to March 3, 2014 in the Valentine's Day Massacre Special pack, and later re-released indefinitely on all platforms as part of the GTA Online: Be My Valentine update.


Grand Theft Auto V

The Gusenberg Sweeper is based on the .45 ACP M1928A1 Thompson Submachine Gun (popularly known as the "Tommy Gun"), which is famous for its role in 1920s gangster culture and in the Second World War. The name of the weapon is a parody to The Trench Broom and the Chicago Typewriter, two informal names of the Thompson Submachine Gun[1]. The stock is derived from the later M1 & M1A1 Thompson, used during World War II. The Gusenberg Sweeper is fitted with a 30-round drum magazine, which is also common in mobster culture. The wooden handguard and stock are noticeably discolored due to wear and tear.

Even though it is a submachine gun, it is classified as a light machine gun and such, it is placed with the MG and the Combat MG, possibly due to its sheer size (much even larger than the SMG).

In the Xbox One, PlayStation 4 and PC versions, the Sweeper's firing and reload sound effects sound lower in pitch when using the first person camera mode.


Grand Theft Auto V

The Gusenberg Sweeper's biggest advantages are its fire rate and damage per shot. It fires at 555 RPM, which is close to the fire rate of the AP Pistol and the Combat MG, and deals 34 damage per shot, being on par with assault rifles. It outclasses all other SMGs in damage per shot and fire rate. This puts the weapon in terms of damage-per-second among the best submachine guns to use.

Accuracy is exceptional in short bursts, and the range is shorter, comparable to that of other SMGs. It has a larger spread than other submachine guns. This makes the Gusenberg Sweeper ineffective at long range, however, single shots or short bursts cut down on recoil and make it a very accurate weapon.

A bizarre trait for the weapon is the ammo capacity. A stock magazine only holds 30 rounds, and it can be upgraded to 50 rounds. This capacity is mediocre for an LMG, and due to the high fire rate, it is not uncommon to be caught in reloads during a firefight.

Another downside of the weapon is the attachment selection. It can only mount the Extended Clip, unlike other SMGs/MGs. This means the player cannot upgrade its stats, limiting its effectiveness.

Compared to other MGs, besides the ammo capacity, it has a better fire rate but lower damage than the standard MG. The Combat MG completely outclasses it, having higher damage per shot, accuracy and ammo capacity.

In conclusion, the Gusenberg Sweeper should be treated as a submachine gun more than a light machine gun. It is ineffective at long range, and its low ammo capacity makes it impractical to use, but this can be disregarded if not fired fully automatic. However, at medium and close ranges, it is a very effective weapon, having a high damage per shot, akin to assault rifles, and a high fire rate.

Despite being chambered in .45 ACP, it ejects shell casings that appear to be 7.62mm casings, most likely due to re-used assets with other LMGs.
