Personally, I hate guns. I just.. Don't enjoy their presence.
But I legally own a cheap "Mossberg 88 'Maverick' " 12 gauge pump action shotgun with a 6-shell capacity tube (Which was a gift from father) and a Ruger P95 which I only carry with me when I go on out of city trips such as camping and so on.
Otherwise I just snap a Leatherman® Rev multitool on my belt and I'm good to leave home in any scenario. Alongside, I also keep a Victorinox SwissCard inside my wallet, which has been genuinely useful in ripping apart stubborn sandwich boxes for years.
Yes I don't want guns, I just couldn't sell them. I keep the former maintained and oiled out of respect as it was a gift.
