The word polymer bugs the hell out of me. It's extremely overused by people who don't have a CLUE what it means. Folks seem to think that polymer is a material, when polymer really just describes a property of MANY vastly different materials. Plastic would be more correct. Thermoset or thermoplastic, even more correct, depending on the particular plastic. Even plastic is more of a property descriptive than a correct name.
I fault Gaston Glock. He played on the American public's vast ignorance of anything vaguely technical and their susceptibility to marketing BS. He said once that his guns weren't plastic, that was for cheap $200.00 guns. His guns were POLYMER. Direct, intentional deception. And the American public are too ignorant to know and too gullible to question it.
Another one is people referring to a magazine as a "clip". A magazine is a feeding device that contains a spring and a follower.
A clip is nothing more than what it's name implies, a sheet metal clip that merely holds rounds together for loading into a magazine(stripper clip, or more correctly a charger) And an en bloc clip as used in Carcanos, Mannlichers, M1 Garands ( pronounced gare-und, NOT guh-rand)
Popular usage does not make it correct.
There are a lot of words that have been buggered up that just twist my nipples.
