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. Fully 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.

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, so a crack shot can most certainly kill opponents 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 stomach, head, or groin. Damage is high enough to (usually) break police helmets in two shots, one with full damage upgrades. Weaker grunts, like merchant bodyguards, die to limb shots from an unupgraded revolver, while later game Dvali tend to get knocked down.

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 black armor cops with a body shot, which also means you can't drop most ARC soldiers or shadow ops operatives, either. Fortunately, the standard revolver has a high fire rate when upgraded along with comfortable handling. The base ammo isn't strong enough to kill standard police in one shot, let alone a guaranteed helmet break on the second shot (unless fully upgraded). With some practice, you'll find that one can land shots at the crack between cops' armor and helmets, which kills them. Up close, a stomach or crotch shot can kill, but you will need damage upgrades for this to be reliable. Basically, two shots kill anyone with even the weakest armor protection at base.

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 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 metro cop from the back at 30 meters, or 2 shots at 29 meters.

Fully upgraded, the standard revolver is powerful enough to dispose of black armor cops in 5 body shots from beyond 30 meters range using standard ammunition, which is quite an achievement for such a straightforward weapon.

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, that is to say, you can deplete an entire 9 round cylinder in less than 2 seconds, if your finger's up to the task. While damage seems to be only slightly higher than the base revolver, note that this weapon can only use .357 AP ammunition, vastly increasing its damage. Few enemies can stand up to repeated hits from this gun. Fully upgraded, a pointblank shot to the groin or stomach leaves black armor 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 your 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. The catch, and there's always a catch, is that the classic revolver a) cannot use ordinary .357 rounds, b) has only 50 meters of range, and c) the 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.
