I did not say that Germans had NO guns, I said that they had FEW guns and no means to obtain more.
By the way, if you had a gun and no groceries and were not a thief, where would you take your gun to borrow money against it?
What religion might predominate among pawnshop owners?
It certainly made sense for Hitler to confiscate guns. But there were not enough to overthrow any government, assuming that this would have been possible. Germany's police were quite well armed, because there was a LOT of unrest in the Reich from 1918 through 1933. AS I recall, even my college European history books failed to describe Germany in this period.
When I was teaching in the Cascades in 1964, I spent a lot of time talking with the physics and chemistry teacher, Herr Heinrich Schapp, who was born in 1923 and grew up in Germany, so I ordered some books from the Bookmobile and read up on it. A rather exciting time. Herr Schapp loved to talk and liked my cooking better than his own. He was dragooned for expressing anti-Nazi musings into the Afrika Korps, and spoke both German and Frisian, which is very like English. He was captured near the Kasserine Pass in Tunisia and sent to an Alabama POW Camp.
In small towns in Missouri, there are very few Jews, but if you wanted to find one, the town pawnshop would be a likely place of where to find one.
Of course, you could also search the phone book for names containing the syllables Gold, Silver, Berg and Blat.
Germany had pawnshops and they were very often run by Jews. That is why Hitler was able to stir up so much hatred of Jews: they are the one's that ended up with the signs of wealth from Grandpapa's estate, as the financial crises in the Reich after WWI impoverished nearly everyone. People who dealt in gold tend to never be impoverished anywhere.
I do not recall Herr Schapp telling me anything about any gun confiscations. His family was from Bremerhaven, and volunteered to develop land annexed from Poland in 1941, so I imagine they were fairly poor. Middle class urban Germans were not interested in becoming farmers.
