Anybody into guns also knows the term "clip" and what it means even though it is "incorrect".
I seldom heard the term "magazine" referring to a container of cartridges until the last 20 years or so.
My father, who was a Marine in the Pacific theater in WWII, my grandfather who was in WWI, and our neighbor who was in the Army in WWII, as well as every other "old timer" hunter I knew all called "magazines", "clips".
Never, in the '60s and '70s did I hear the word "magazine", except for referring to "Outdoor Life", "Look", The Saturday Evening Post", etc.
There is often a "right word" for something, and there is the slang which everybody calls it.
Yes, that's because the rifles they were issued used actual "clips".
The last person that I heard of calling a magazine a clip was the dude who said "don't have a clip in it, bro'" just before his buddy got shot by a crazy chick on drugs pointing a handgun around at people.
The purists are very tolerant. A magazine on a ship is a room.
The M1 rifle did indeed use a clip but I am pretty sure they referred to M1 Carbine magazines as clips also when I fired my first one in 1955.
