You know what I meant by 167 years - this is the exact reproduction of the 167 years old technology. Of course it can be lethal, just as prehistoric weapons can be lethal. But the law in all or most countries distinguish modern firearms from muzzleloaders. So I don't agree that they disturb my neighbors with silly questions and keeping me wait for weeks, I'm not buying a Glock. Consider this: what if they talk to some neighbor who doesn't like me for any reason; or what if I'm a loner and neighbors know nothing about me, than an officer can conclude what ever he wants, which is not ok with me. And what will neighbors think after such visit? Will they know that it's a muzzleloader and not a modern handgun? They may just start to think after such visit by a police officer that I'm some weirdo who will now walk around armed (here where I live people usually don't own firearms). I graduated from law college, while most police officers have only a high school education - and now they'll judge me. I don't like it, no-one would.
Those neighbors can also be very much anti-gun and create issues.
