that’s not rly how guns work, if I was rly good with guns I could kill someone with a .22lr if they had a 9mm and were bad with guns, the thing is different guns are good for different things, you won’t be able to use a shotgun effectively at 50m++ for example or a sniper rifle at 7m–

also how good you are with guns isn’t a genetics thing like physical strength

of course I’d rather live in a world without guns, but the moment one person has a gun everyone should have one
