NOPE: He actually liberalized them for all bit the Jews!
from SLATE:
University of Chicago law professor Bernard Harcourt explored this myth in depth in a 2004 article published in the Fordham Law Review. As it turns out, the Weimar Republic, the German government that immediately preceded Hitler’s, actually had tougher gun laws than the Nazi regime. After its defeat in World War I, and agreeing to the harsh surrender terms laid out in the Treaty of Versailles, the German legislature in 1919 passed a law that effectively banned all private firearm possession, leading the government to confiscate guns already in circulation. In 1928, the Reichstag relaxed the regulation a bit, but put in place a strict registration regime that required citizens to acquire separate permits to own guns, sell them or carry them.
The 1938 law signed by Hitler that LaPierre mentions in his book basically does the opposite of what he says it did. “The 1938 revisions completely deregulated the acquisition and transfer of rifles and shotguns, as well as ammunition,” Harcourt wrote. Meanwhile, many more categories of people, including Nazi party members, were exempted from gun ownership regulations altogether, while the legal age of purchase was lowered from 20 to 18, and permit lengths were extended from one year to three years.
The law did prohibit Jews and other persecuted classes from owning guns, but this should not be an indictment of gun control in general.
