Feb. 21 – On this day in Montana history in 1918 the state’s first gun registration law was enacted. The measure was approved 72 to 1 in the House, and 26 to 10 in the Senate. “Firearms” were defined as “any revolver, pistol, shotgun, rifle, dirk, dagger or sword.” It wasn’t passed for the reasons it is discussed today, but rather in the midst of World War One war hysteria. It was quickly nullified at the end of the war except for “non-citizen aliens.”
