Because it’s a different thing lol
I don’t personally care if you call a dog a banana, but it doesn’t magically make the two the same thing.
If I’m at the range and I have my two weapons, one with a clip and one with a mag, I ask for a mag and you hand me the clip…it ain’t going to work, because it’s a different thing.
This isn’t to make you feel bad, anymore than a dictionary is to make people feel bad, they are different words for different objects, sorry.
With my students, if they call the Delta on the chart Bravo, I will correct them and so them where to find the answer, like I did with you and the article on mag vs clips, I’m not doing this to feel superior, I’m doing it to try to help, and because no matter what they say, I won’t say Delta and Bravo are the same thing for my student, anymore than I would say the word clip and mag are interchangeable.
