I own firearms so that I may, should the need arise, shoot people. I care not a whit about mechanics, artistry, engineering, competition, hunting, or collecting for the sake of collecting. I have as many firearms as I need for them to each do their jobs. I can walk past the firearms at a show or shop without feeling the need to buy a new one because I already have what I need.
I have a full-sized pistol that i carry when I do armed security, and it stays in the bedside stand at night for home protection. It is backed up by a 12-gauge shotgun in case that would be a better application depending on the circumstances.
I have an easily concealable pistol that I CC when not in uniform, and I have a second pistol of the same make and model which stays at home. If I ever do need to use the CCW pistol to defend myself and it is confiscated from me after the shooting, it's twin will fill the empty holster as soon as I get home.
I have an older full-sized pistol that I carried for twenty years until I found something better to replace it, and although it's as close to a "safe queen" as I have, it is still a fully functional tool and I have no reason to get rid of it.
Regarding End of the World scenarios, because I live in the Las Vegas valley along with 2 million other people, a desert surrounded by much more desert, a hunting rifle or shotgun would serve little purpose in a long-term catastrophic situation. For folks like me, preparation is key, not hunting/fishing/foraging.
All of my pistols use the same calliber cartridge, and I practice (dry and range) with all of my firearms. If I do purchase another pistol in the near future it will probably be a revolver with a shrouded hammer for my gf, and that of course will be hers and not mine.
For me, firearms are just another set of tools. I may appreciate the craftmanship or beauty of a hammer, but I don't drool over a rack of them when I walk down that aisle at Home Depot, and don't show off my screwdrivers when my buddies come over, and I don't enter competitions to win a medal for being the fastest guy with an allen wrench.
Edited to add a very minor point: I will probably also purchase a .22 rifle for the inevitable TEOTWAWKI/Zombie Apocolypse for the job of pest control/protein harvesting. My gf will not be happy with the idea, but I bet Alley Cat Stew smells awfully good when your tummy has been empty for a week.
