Germany in the 20ties and 30ties. Even if you count conservatives delivering political power to the Nazis as a revolution. I'll paraphrase German Wikipedia:
Immediately after WWI, private gun ownership was outlawed, however this was impossible to enforce because guns were not registered. Especially post Freikorps right wing militias (Schwarze Reichswehr) were well armed
In 1928, Germany got its first unified gun law. Private gun ownership was allowed. However, prospective buyers had to prove their "reliability" and an actual need for the weapon. Weapon owners needed a Waffenbesitzkarte and a Waffenschein (a license to be carried on the person)
After 1933, the Nazis used the existing laws to harass Jews and political enemies: the police would withdraw the permit and use this as a pretext to search someones premises for weapons. This was targetted widely at Jews (in '33, Berlin's police chief withdrew all weapons permits from Jews) but also at other political enemies.
Later, the Nazis would control who gets a gun: gun laws were relaxed for party members (a license was no longer necessary to carry a handgun, starting at certain ranks within NSDAP, SA, SS or Hitler Youth among others), while "Gypsies" and other were banned from gun ownership. Jews were excluded from gun or ammunition manufacture and sale. at the same time, the restrictions on longarm ownership were relaxed, permits were only required for handguns. A specific goal of this law was Wehrhaftmachung des Deutschen Volkes, to ready Germans for war.
Later in 1938, after the November pogroms, a bylaw specifically forbade Jews guns or any other form of weapon ownership
So you certainly can say that in the 20ties, Germany increased gun rights - from none at all to legal gun ownership, based on permits.
Starting with the Nazi regime, the picture gets more complex. For a majority, the change in '38 meant easy access to long guns. For some organized Nazis it eased the carrying of a handgun. But at the same for many the regime deemd enemies, legal gun ownership had become impossible.
I don't know if the Nazi or Hitler ever systematically laid down their thoughts on private gun ownership, if they even were that coherent on that issue. They certainly didn't envision a disarmed population.
