Remember the time and location. They were foreign pilots in the middle of a civil war. The PPK and PP could be easily carried at all times, even pocketed.Gebirg,
FYI, I knew a Condor Legion pilot (Colonel) in 1970 who said, "If you wanted a badge of office you wore a P08. If you wanted a real & useful pistol you aquired and carried a PPK."
Fwiw, I agree. The PP & the PPK are NICE.
