I guess you could say I'm old school, I don't think anyone should have to pack anything with a magazine. I don't own a gun, but if I did I wouldn't need anything more than a six-shot revolver and a double barrel shotgun.
1. If you shoot something 6 times (or twice with a double barrel shotgun) and it doesn't die, it deserves to live.
2. Or; if you need to shoot more than 6 people, you're doing life wrong. Reconsider your life choices and/or just shoot yourself.
3. Remember, if you're considering a mass shooting or murder suicide, you're probably going to be dead at the end. Consider just shooting yourself first. That way you never run out of ammunition!
4. The other great thing about revolvers, you can tell with a spin and a glance whether they're loaded. None of that 'forgetting the one in the chamber' and accidentally shooting granny bullshit.
This has been a public service announcement.
