Wow I had no idea this was such a heated topic.
I typed this out last night before bed, checking it now an hour before lunch, 4 pages of responses..
Regardless of how you feel about this topic, it does seem clear it should be addressed. I mean the % of SR players that are even on these forums at this point has to be under 1%.
Whomever quoted a Wikii about that indicated that the term clip was commonplace, please remember that Wikii's are created and maintained by the public, not industry experts... the same uneducated public that commonly refers to magazines as clips.. I don't think anyone who works with firearms, or has formally trained with them ever makes this mistake.
There are 2 firearms that come to mind as clip using, one is an SKS with a non removable magazine (its not internal, its held on with a screw) it is loaded by pressing a rounds off a clip down the top of the riffle, the empty clip drops out the bottom. and the M1 Garand you push down on the back of the clip and it holds them down inside the riffle on the clip, as the rounds are shot the clip slowly climbs out of the riffle until it is launched clear after the last round.. There is no way to unload these weapons without ejecting all the rounds in some fashion. BTW both these firearms predate 1947, nothing comes to mind as a military used riffle newer then 1947 that uses a clip.
There is a type of clip called a moon clip, that is used for a specific revolver, but it is exactly a clip, and is used to speed load the gun..
My point is still true, to people who spend a lot of time with firearms, the term clip is ignorant. There is no other viewpoint, especially if they have taken to time to explain the difference to the new people and they still call mags, clips..
To the person that pointed out that magazine is 2x as long as clip, I offer that Mag is 25% shorter than clip and perfectly acceptable in all cases
In game mechanics if they called Magazines (M), and internal Magazines (IM) no one would be confused..Then when I buy clips for my firearms, it would be to load them into my (IM), or to speed load them into my Mags..
So everyone is happy, and you stop propagating ignorance to a new generation of gamers.
