Do you think it is normal having firearms?

[Grey Acumen]

Some guns are more reliable, while other guns have better accuracy, or range, for those that hunt for sport. Or perhaps you might have 1 that you can carry in case you need to repair your other gun.
Or perhaps you might simply have an appreciation for the craftsmanship that goes into the various different firearms. People aren't restricted to only having 1 car, so why should they be restricted from having 1 gun?
Heck, the people who do own multiple guns usually do it out of a respect and appreciation of the gun. You only need one gun to kill a person, having 17 guns doesn't mean you can or expect to be able to kill 17 times the number of people with them.
