First off, welcome to our world. You have a long, happy life of shooting fun ahead of you. I am envious of your youth and limitless opportunity.
Now then, youngster, I hate to break it to you, but you are a hopeless, died-in-the-wool, modernist. Every gun you enjoy as "traditional" was, at one time, a new-fangled atrocity.
Like that 1911? To the nineteenth century, revolver-centric mind, it was an abomination. And the brass cartridge? Anathema to the cap-and-ball crowd. And so it goes, back throught flint locks, match locks, wheel locks, and so on. What do you think a longbow archer thought the first time he laid eyes on a crossbow? And why would anyone need a sling, when he's got a perfectly good throwing arm?
Age will give you perspective. Some day, one of your grandkids will tell you, "Rail guns and laser vaporizors are OK, but I really like the old, traditional polymer, striker-fired bullet launchers. C'mon Grandpa, let's go kill some cans."
