There is rarely a new person to the gun community who doesn’t accidentally use the word “Clip” instead of “Magazine”, with resultant look of disgust from more seasoned members. From better members of the community, it’s a quick vocabulary lesson, and they move on, minimizing embarrassment. Others, well, I haven’t run into too many of those.
If you are new, and have been caught once again, a famous WWII rifle can come to your rescue. I was able to fire an M1 Garand vintage rifle with my brother. It was a bit of nostalgia for me, as my grandfather died in WWII, but being in infantry, must have carried one. I was extremely pleased to find out that Garands do not have “Magazines”. They literally use clips… thin metal disposable (in WWII, not now) carriers for 8 rounds, designed to help soldiers load faster under fire.
That might also explain how we got this from the movies… WWII movies with Garands probably would have used “clips” correctly.
Magazines are, of course, more substantial, last longer, hold more and load better. However, next time you start to embarrass yourself, you can come back with, “I was waxing nostalgic, thinking about the M1 Garand, for THIS gun, I clearly meant ‘Magazine’”. They may not believe you, but perhaps you’ll get some credit for knowing about a classic rifle.
