The M9 SD in DayZ.
- "Silenced semi-automatic pistol
- — In-game description
The M9 SD has an all-black finish, a suppressor and non-adjustable iron sights. The suppressor greatly reduces the sound and muzzle flash produced when firing.
The M9 SD's cartridges deliver moderately-low damage of 889 blood and produce a small amount of recoil. The suppressor and SD ammunition reduce the audible range to zombies to less than 0.1 of a meter from the shooter's position. The effective range of the M9 SD is up to 75 meters.
The M9 SD can kill a player in up to four shots to the body, or one shot to the head, as with all weapons and ammunition in DayZ. The M9 SD can kill a zombie in up to four shots to the body. Viral zombies require more shots to kill than regular zombies.
The M9 SD is a very rare sidearm that has a 0.52% chance of spawning in Military loot spawns, but not Deer Stands and a 0.90% chance of spawning in Barracks. The spawn chances are equal to 13 out of 2,500 and 9 out of 1,000.
Although considerably weaker than the M1911 and Revolver, the M9 SD has a significantly larger magazine capacity, making it one of the best sidearms for raiding cities and small towns. The weapon is also very quiet and produces a dull muzzle flash. This makes it very effective when trying to remain undetected from zombies or players. The M9 SD will take up five slots in a backpack, as do all sidearms.
The M9 SD's biggest disadvantages are that its magazines are very rare - 0.48% chance of spawning in Military loot including Barracks, but not Deer Stands - and the M9 SD cannot take other magazines.
The M9's real life counterpart is the Beretta M9 - a semi-automatic pistol manufactured by Fabbrica d'Armi Pietro Beretta in Italy. The Beretta M9 fires 9×19mm Parabellum cartridges, has a fifteen round capacity magazine and has been in service with the United States Armed Forces since 1985.
