The Walther P38 then?
Fun fact: the word "German" is derogatory. It means "men with sticks". They prefer "Deutsch".
So does that mean I can carry a Musket?
Just be sure to make every shot count.
"Could you please stand in an orderly line behind each other and hold still for a moment?"
Considering they don't have any firearms, probably won't be too hard.
The gun that won the west is also an appropriate choice. A Winchester 1873 can fire quicker than a musket.
I grew up on this https://www.imdb.com/title/tt0051308/ and Star Trek TOS.
Many a shot was fired from imaginary guns and many brave boys lost their lives. But not quite because they'd always manage to fire off one last deadly parting shot.
Took a little doing to find the above, in Germany it was called 'Westlich von Santa Fé' and I thought it was called 'John McLean'. Must've been in the 70s, we didn't own a TV then.
