9mm pistol
From Killing Floor Wiki
For the original Killing Floor weapon, see 9mm tactical pistol.
The 9mm Pistol is the backup firearm for each Killing Floor 2 perk. Its damage counts towards the perk selected by the player at the time.
The Dual 9mm Pistols are the dual version of the 9mm Pistol. Brings twice the firepower before reloading, while taking more time to equip and reload.
