Polymer triggers made for Colt Mustangs and variants made 30 years ago are already starting to fail, which doesn't surprise me in the least. Plastics are not gun making materials for any other reason than that of increasing profits. Young people typically don't know any better and blindly assume plastics are equal, and the brainwashing continues.
It is conceivable that the young could be convinced that some new variation of paper is actually superior to steel by greedy manufacturers. Why not? They overwhelmingly voted for Obama!
I've had people in these forums argue that aluminum alloys are good replacements for steel, even though common sense tells us that it has only one superior property, weight.
People buy guns made of inferior materials and then argue that the materials are as good or better than gunmaking steels. Not a big surprise.
