The P08 is a German pistol that was made for officers before the Walther P-38. The magazine differs for every variant. Rick's particular Luger is the artillery model, issued to artillerymen as a cheaper alternative to a rifle. It is different from most models because it has an extended barrel, removable stock, and drum magazine.
Valery is given the P08 by Rick before fleeing the estate. She is only seen using it once, although she always carries it around in her hands. She soon goes to Owen and complains how she can not use her Luger, after which she is he gives her an MP5SFK that he found at the Panama Police station .
