For the younger folks, Guns was the first magazine to break into the firearms field, other than The American Rifleman, which was and is an NRA membership magazine, not generally sold to the public. The NRA interest was primarily in target shooting; their collector magazines were yet to come.
The only other general circulation magazines that even mentioned guns in other than a negative manner were the three "sporting" magazines, Field and Stream, Outdoor Life, and Sports Afield, and they stuck to "sporting" guns; articles on military surplus or handguns were definitely not welcome.
There were a few gun periodicals of limited interest and circulation, like Muzzle Blasts, and some hunting publications by state fish and game associations, but that was about it. Once in a while Popular Mechanics or Mechanix Illustrated would do a gun article, or one of the "men's" magazines, Argosy or True, would publish something involving guns, usually a "rambo" type story filled with gung ho and gun errors.
So, a salute to Guns. The competition is greater now, but we all have benefited by their entry into an unfriendly world in January, 1955.
