There is a quote going around the Net being attributed to Hitler:

This year will go down in history! For the first time, a civilized nation has full gun registration! Our streets will be safer, our police more efficient, and the world will follow our lead into the future!

This is of course complete bunk. Hitler never said such a thing. Germany had enacted tough gun control laws in 1928, years before the Nazi rise to power. Instead of banning guns, Hitler instead expanded gun ownership for German citizens (he’d stripped the citizenship of undesirables already) to levels which one cannot even get inside of the United States. The 1938 German Weapons Act actually relaxed all gun ownership restrictions save on pistols. A German citizen could own a fully automatic weapon complete with grenade launcher, legally, under Nazi control.

Advocates of Second Amendment rights are often tricked into using the "Hitler's gun grab" argument, then embarrassed and discredited when they are told that Hitler actually liberalized Germany's gun laws.

Weimar Republic already had restrictive gun laws, which were actually liberalised by the Nazis when they came to power.
According to the Weimar Republic 1928 Law on Firearms & Ammunition, firearms acquisition or carrying permits were
“only to be granted to persons of undoubted reliability, and—in the case of a firearms carry permit—only if a demonstration of need is set forth.”
The Nazis replaced this law with the Weapons Law of March 18, 1938, which was very similar in structure and wording
, but relaxed gun control requirements for the general population.
This relaxation included the exemption from regulation of all weapons and ammunition except handguns,
the extension of the range of persons exempt from the permit requirement, and the lowering of the age for acquisition of firearms from 20 to 18.

• Hitler's gun restrictions

Although Hitler was adamant in opposing gun ownership by conquered peoples, his government slightly liberalized gun laws inherited from his predecessors.

Those laws were enacted in 1928, five years before Hitler assumed control of Germany. They restricted ownership to responsible citizens who could prove a reason to own firearms. Hitler actually lowered the age threshold of gun ownership from 20 to 18 and further liberalized gun ownership by revoking the necessity for registering long guns. Muzzle-loaded hand guns were also exempt from registration. Hitler's government further extended gun permit validations from one year to three. It also removed restrictions on the number of firearms and ammunition an individual could own.

Hitlers government also lightened gun laws by removing the requirement to obtain a permit to purchase handguns by individuals who held a gun-owners permit. That is, if one carried a permit to carry a gun, he no longer needed to acquire another permit to purchase additional guns. The same was true of those who held a hunting permit. Hunting permits, it should be noted, authorized Germans to carry handguns as well as hunting guns.

Hitler-era gun laws prohibited criminals, the mentally handicapped, those convicted of treason, persons under age 18, vagabonds and gypsies from owning or carrying firearms.

Why was Hitler comfortable doing this, when all common wisdom is that dictators eliminate gun ownership? Because Hitler ruled from a popular standpoint. He had little to fear from German Citizens, and for those who would stand against him, he made sure to strip away their citizenship, therefore their rights to firearms. This left him with a well armed nation who worshiped the ground he walked on. This is one of the reasons why the closing days of World War II were so bloody. The majority of German citizens, however, were untrained, so ineffective on the battlefield against the well trained Allied forces.

Hitler did discuss gun confiscation in 1942, but not against his own citizens, but against the people who he had conquered:

The most foolish mistake we could possibly make would be to permit the conquered Eastern peoples to have arms. History teaches that all conquerors who have allowed their subject races to carry arms have prepared their own downfall by doing so.
German troops alone will bear the sole responsibility for the maintenance of law and order.
