Modification of the gun for ability to use bullets of the 9x18mm calibre.In-game description
The Walker 9x18 is a unique pistol featured only in S.T.A.L.K.E.R.: Shadow of Chernobyl.
This modified Walker P9m fires 9x18mm rounds instead of 9x19mm rounds and has an addtional 50% increase in reliability compared to the standard Walker P9m.
This is Mole's handgun. After the player rescues Mole (and he tells the player about the Agroprom Underground), he will stay near the entrance to the sewers for a little while. Afterwards, he will then return back to the buildings he and the stalkers were previously exploring, and is likely to be killed by the Spetnaz team that appears shortly after saving him. The handgun can then be looted, assuming he perishes. The player must not enter the Agroprom Underground beforehand, as doing so will result in Mole disppearing for the rest of the game.
