Mustang Arms .357 Magnum

The 'Mustang Arms .357 Magnum is a weapon in Deus Ex: Mankind Divided. The standard revolver is a derivative of Deus Ex: Human Revolution 's Diamond Back .357, which also appears in Mankind Divided as a variant of the standard revolver.

Overview
The revolver is a dependable weapon useful for lethal, non-stealth playstyles. The revolver is particularly notable for its high damage per shot.

Revolver AP ammunition is the most powerful ammunition against turrets, robots, and other hard targets such as metal doors. AP ammunition allows the revolver and its variants to dispatch robotic targets more easily than any other weapon. Revolver AP is also very effective against personnel. Without upgrades, a single body shot is enough to kill low-tier unarmored opponents. Fully upgraded, a single body shot is capable of killing "veteran" level Shadow Operatives. Armored police, certain "elite" level Shadow Operatives, EXO-suits are among the few personnel opponents that can tank more than two body shots. Unfortunately, revolver AP ammunition is the rarest non-grenade ammunition in the game. Roughly 180 such bullets can be found, and fully half of them must be purchased. See the page on ammunition for details on locations.

The standard revolver is the only variant that is compatible with the standard (non-AP) revolver ammunition.

An unupgraded standard edition revolver will be added to the player's inventory during MM1: Black Market Buy if the short-ranged lethal method of engagement is picked, as well as 18 .357 standard bullets.

Classic .357 Magnum Revolver
Included as part of the Classic Gear DLC, available as a free download.
 * Has the highest per shot damage once fully upgraded, but it has the lowest accuracy, slowest base rate of fire, and slowest reload speed.
 * Only accepts Armor Piercing rounds.
 * Has a maximum range of 50 meters.

Otar's .357 Magnum Revolver
A custom-made revolver and trusty sidearm of Otar Botkoveli. The weapon can be obtained only by looting it from Otar's body after killing or knocking him out, either during the mission The Calibrator, or inside the Dvali Theater when Prague is under martial law.
 * It is the only sidearm that can use a scope, coming pre-equipped with a 4x scope. It is the most accurate variant, has the highest base damage, and has the least recoil, but has the smallest magazine, lowest max rate of fire.
 * This weapon cannot be upgraded.
 * Only accepts Armor Piercing rounds.
 * Has a maximum range of 65 meters, the longest of the three revolver variants.

Standard Mustang Arms .357 Magnum
The revolver is a dependable weapon, featuring a non-obtrusive iron sight and good accuracy even without upgrades. The standard revolver has a range of 55 meters, but standard .357 bullets only generate sound out to 45 meters, making it possible to kill an opponent before they even notice they're under fire. Even without upgrades, the standard revolver packs enough punch to kill unarmored thugs and grunts with a single shot to the torso. Damage is high enough to (usually) break police helmets in two shots, or one with full damage upgrades. Weaker grunts, like merchant bodyguards, die to limb shots from an unupgraded revolver, while Dvali thugs later in the game tend to get knocked down. The standard revolver has a high fire rate when upgraded, along with comfortable handling.

The gun has some weaknesses. Without upgrades, and even with them, getting swarmed puts the player in a difficult position. Ammunition, of both kinds, is primarily bought in stores, and is very hard to come by in the world. Fully upgraded, the damage is still not enough to drop armored police and the heavier types of Shadow Operatives with a body shot. The base ammo isn't strong enough to guaranteed helmet break on the second shot (unless fully upgraded). It is, however, possible to land shots at the crack between the armor and helmet for an instant kill.

Overall, this weapon shines at handling small groups, regardless of what gear they have, what level they are, or who they are, especially at close range. Note also that most .357 hits that don't result in kills, or strike armor, lead to the enemy entering a long "ouch!" animation, like they do when hit with the sniper rifle. Even high-morale cops sometimes react like this when hit from 50 meters away. The standard revolver, without upgrades, requires 3 shots to kill an unaware police officer in light tactical gear from behind at 30 meters, or 2 shots at 29 meters.

Fully upgraded, the standard revolver is powerful enough to dispose of armored cops in 5 body shots from beyond 30 meters range using standard ammunition. When using AP ammunition, the fully upgraded standard revolver is able to dispose of sentry bots in just two shots.

Classic .357 Magnum Revolver
The lower base rate of fire is deceptive, as the hair-trigger upgrade will turn this weapon into a rapid-fire weapon just like the standard revolver, allowing an entire 9 round cylinder to be fired in less than 2 seconds. Damage is slightly higher than that of the base revolver.

Note that this weapon can only use .357 AP ammunition, vastly more powerful than the base ammunition. Few enemies can stand up to repeated hits from this gun. Fully upgraded, a pointblank shot to the groin or stomach leaves armored cops at about 15% health, and in a long "ouch!" animation. At 25 meters, the same cop is left with slightly less than 20% health. Since rate of fire is so high, and the handling almost identical to the base revolver, the classic diamondback is a contender for most powerful weapon in the game. EXO-suits also fall to four quick shots.

Drawbacks of this weapon include its inability to use ordinary .357 rounds, its 50 meter range, and rarity of .357 AP ammunition.

Trivia

 * The Mustang Arms .357 was likely inspired by the concept.
 * The Classic and Otar's .357 variants has the upgraded barrel of the explosive rounds kit from Human Revolution, but fire Armor Piercing bullets instead. "Diamond Back .357, MA-HEX20" is written above the barrel and "MA-HEX20, High Ex/Incendiary, Tracer" is written below the barrel.
 * The classic revolver can hold up to 9 rounds, 2 more than its counterpart in Deus Ex: Human Revolution.
 * The classic revolver's description claims that the increase damage stems of having a larger barrel, but no difference in barrel size is visible. Moreover, considering that both the standard revolver and the classic revolver use the same ammunition, having a larger barrel would greatly decrease the accuracy and power of the weapon, as the round would have room to bounce against the sides of the barrel so as to lose energy before tumbling out of the barrel.
