Guns as a means of protecting ones self is kinda a hard argument. You gotta be a really good shot to be effective with anything other then a shotgun if your dealing with a real, solid threat situation, where you'll be caught off guard and not in a good place to turn the tables. Which means going to the range/wherever you shoot and shooting a lot, like say a box of 50 rounds of 9mm, common round and good quantity, cost 20 dollars ((It rarely will)). You'd probably need to go through, being incredibly lax in practice and such, 1000 rounds a week or so to keep your skills honed. That's about 20 boxes of 50 round ammo, which comes out to 400 dollars a week, 1600 a month, to be good with a handgun, rather then a shotgun or rifle with grip, or one of those cheating pistols that might as well be a rifle type guns.
I see them more as something for recreational purposes, a nice hobby to keep your hand/eye coordination and focus up like Darts or Golf, only funner and with a bit more excitement every time you hear a satisfying pop through the thick earmuffs and see a breif flash through the cheap plastic safety glasses. You can kill people with guns, but you can kill people with darts to. And there's more then one story of people bludgeoning others to death with golf clubs. So yeah, it's more just irresponsible gun owners who either sell guns to people who are gonna do bad stuff with em, like selling them out of a van in a bad neighborhood, or leaving them in places they can get easily stolen either from relatives or strangers doing a robbery.
This is mine. It's a Ruger P95. 9mm.

It's simple. It's durable. Easy to take apart, clean, put back together, and fire. It was cheap enough to cost less then 500 but not so cheap you know its gonna be a piece of ****. And it's from a common brand so replacement parts aren't going to be like finding a needle in a internet haystack. It does what a gun should do, without costing me a good chunk of paycheck and a sore shoulder.
In a lot of ways, a gun is a lot like a car, now that I think about it.
