The most expensive non-energy handgun in the game, the PPK12 has an unrivalled range, accuracy, and damage-per-action-point in its class. Its ammo capacity is also top-notch. The 2mm cartridge used by the Gauss pistol has good armor penetration, enabling the weapon to be used to lethal effect against any kind of opposition.
This pistol averages 40.27, 28.64, and 13.73 Hit Points against unarmored, medium-armored, and maximally armored enemies, respectively. It is especially deadly with critical hits because when compounded with the armor-piercing critical effect, the 2mm round's armor-penetrating properties completely negate the Damage Resistance of any target.
The PPK12 has no weaknesses strictly from a combat standpoint, however, the scarcity of its ammo type may necessitate the use of a sidearm for dealing with lesser threats, in order to save the 2mm EC for the most dangerous battles.
