The **Thompson M1A1**, or the **M1A1** as it is known in-game, was introduced in the v0.6.5 "*Gunfight at The Deadeye Saloon*" update on November 9, 2018. It is an SMG that runs on .45 ACP.

## Info

Although the M1A1 replaces the MP5 in the Desert Map, the Weapons are highly different from one another. It's only found in the Desert Map during the desert Events, relatively common in the Map. Other maps that have the M1A1 are the Potato Map and the Savannah Map.

## Strategies

### Using

* The M1A1 is a very versatile gun, as it is decent at mid and long-range and is acceptable even close-range in open areas (although it will be out-classed by most other shotguns and SMGs). However, it's best-used mid-range, as it's accurate enough and has a good DPS.
* The M1A1 also is very common in desert mode, making it easier to find a gun. Unless you want to replace it, this gun can be used the whole game.

### Countering

* When an opponent uses an M1A1 in close range, you can use other more powerful SMGs or Shotguns to defeat them.
* Pressuring with grenades will keep your opponent on the move and cause them to make less accurate shots.
* Pick them off with a sniper rifle, as you will most likely be able to outrange them.

## Trivia

* It's the fourth WW2-era American weapon, with the M1 Garand being the first, the BAR M1918 being the second, and the M1911 being released at the same update.
* It's the first SMG to be added in the game not to use 9mm.
* The M1A1 and its predecessors had several nicknames, including "Tommy Gun", "Chicago Typewriter", "Chicago Piano", and "Trench Broom".
* The M1A1 is the oldest SMG of its class, with one of its variants, the M1921, starting production in 1921, about 45 to 50 years before both the MP5 and MAC-10 in production in 1966 and 1970, respectively.
	+ The M1A1 itself began production in the 1940s during WW2.
* This weapon served the US military from the 1920s to the early 1960s when it was phased out by its lighter, cheaper counterpart, the M3/M3A1 "Grease gun".
* The reload sound for the M1A1 depicts it as having to be cocked after reloading. Cocking an M1A1 using box magazines isn't necessary as the magazine has a built-in bolt-hold-open device known as the "Blish lock", a mechanism that locks the bolt to the rear when it is empty. As an open-bolt weapon, no further working of the bolt is required of the Thompson, and in theory, it would always be ready to fire regardless of whether or not the previous magazine was empty.
* This is the WW2 M1 variant of the Thompson SMG. It lacks the iconic drum magazine compatibility, finned barrel, and the weapon's top charging handle, which heavily contrasted with the iconic M1928 models.
	+ At the time of its introduction, the 30 rounds box magazines were popular and far more practical to carry than the drum magazines. The Unique "Blish lock" for pre-war Thompsons was unreliable and was later scrapped for the wartime models. Added with the high weight that Thompsons were criticized for (about 10 pounds unloaded), the US military decided to use M1928A1 models. Later, M1A1 models were both designed for the lower-capacity box magazine.
* The sprite for the M1A1 correctly has a 30-round magazine.
* With the Firepower Perk, it has 50 rounds, more alike to the common portrayal of the Thompson SMG. However, having this ammo capacity makes no sense for the M1 models due to the inability to mount drum magazines.
* Dual Pistols notwithstanding, the M1A1 is the only weapon with a 30-round magazine that does not "increase" to 40 rounds with the Firepower Perk.
