I am getting weary of dropping extra guns down for myself at a holding spot only to have someone take them. Sometimes I say please don't take guns, sometimes I don't, either way someone takes them. I am aware that some people don't know it could belong to someone, and I also don't excpect everyone to be polite so my idea would be that you hold down a key along with \ so that only you can pick the weapon back up after you've dropped it. When this "only dropper can pick up gun" is dropped it could be a slightly off color from the normal, maybe reddish? So you could use say, ctrl+\ and then only you can pick it back up.
