When taken in contexed, if I say I need a clip for my 1911, anyone that knows what a 1911 is, would instantly get a mental picture of what I am talking about
While you are correct that anyone who knows what a 1911 is will know what you are referring to, most of them will judge you as a neophyte or as a hack who perpetuates a lack of detail. (most will be spot-on in one way or the other)
If it wasn't specifically about firearms, it would still be just as maddening, only more people would assume that you are lazy and/or don't care.
I can't imagine why doing it the proper way is so horribly difficult?
If you really don't know that it's a clip, then you learn. It's up to others to be courteous about it. If you do know -- why continue to do it? If you do it on a world-wide long established internet discussion forum that includes all manner of hardcore gun folks... do you expect that it's "good enough" and blame ruffled feathers on them for your laziness?
It's laziness or ignorance or it's simply rejecting the level of detail that you
yourself expect from others? I would go out on a limb that and say... while non-gun people certainly don't know the difference in detail between clip and magazine-- they also won't be dumbfounded if you say
magazine when they were expecting to hear "clip."
If you are holding a rifle and a non-gun person calls it a shotgun, is that simply "good enough" since you both know that they are simply referring to the long gun and the level of detail just doesn't serve any real purpose?
Or better yet, is it REALLY saving energy, time and daylight to say "clip" instead of using two more syllables to call it a magazine?
It's fine if someone is too lazy to call it what it is and perpetuate the "clip" nonsense. But it's quite a stretch to come to a place such as TFL Forums and do it... and then blame others for pointing it out as if it's such a bother to be reminded that's it's incorrect. (and lazy)
