It's all political/memetic, IMHO. Yeah, the AGs office battle has something to do with it, but the cabal decided to pick one manufacturer to demonize, and it happened to be Glock- because "they" thought Glock was a good target for their bullshit. If you go back to late 90s, (when all this GCA98 bullshit started) it makes even more sense.... if you wanted a polymer framed handgun back then, you were pretty much buying a Glock (there was other stuff back then, like the Sigma, but nobody took most of those guns seriously. I think even colt pinched out a turd many years earlier, called the all american... lol) Some theories of mine- The AGs anti gun cabal probably saw guys waving them around in rap videos, or shit like that, and they also wanted a way to divide gun owners; since even at the time the contingent of fudd shitheads that said "I'll never buy a gun made out of plastic, f**k those things, f**k the people that own them" was much, much larger. Thankfully most of those people either died or got over themselves, but by then, it was too late.
