Here in the US, virtually every time one sees or hears of a WWII era German pistol, the phrase "carried by" or "taken from" a German Officer is included in the description. And its often true, but its not always true. Even when the term is stretched to its limits, to include all the various "officers" in all those different Third Reich "offices" (Amts).
In the combat arms, virtually all officers had a pistol as part of their uniform. A great many enlisted ranks did as well. Mostly there were the classic combat pistols, primarily the P.08 and P.38, but many other pistols were also used. And in support organizations, the pistols carried could be almost anything.
Most German uniforms included a pistol of some kind, and dress uniform often included a dress dagger, or sword. Everything from pocket autos on up were worn by different indiviuals as part of the uniform, and while some groups were ridgidly standardized, many were not, even when they were officially supposed to be.
Considering that there were a really large number of people who's uniform called for them to wear a handgun (whether their official duties ever needed it, or not, it was part of the "proper" uniform), Germany was always short of pistols, sometimes critically so. It wasn't just soldiers, the mayor, the postman, the railroad, all kinds of bureaucrats and workers, probably even the dog catcher, all were supposed to have a pistol on their belt, in dress uniform, if not regular wear. To me, a full flap military style holster for a .25 auto seems a bit much, but rules are rules, right?
Officers, and especially higher ranking ones, in many nations have often had the ability (and sometimes the requirement) to buy their own pistols, and choices that weren't the standard issue guns were quite tolerated, generally. Goering himself had a Colt .38 revolver on him when captured.
