An inanimate object, made of metal alloys, that has the capability to discharge ammunition consisting of a bullet, casing, powder and primer. Despite common misconceptions, guns, or more properly, firearms, do not have a magical, evil effect on anyone who is fit to use them. (Which happens to be anybody who is sane and does not have homocidal or suicidal tendencies) Also, the false belief that banning firearms under law leads to less crimes is false, as what happens when said firearms are banned is the criminals have all the firearms(as they are criminals, and therefore have no respect for the law), and not the good-doing, law-abiding citizens now have no effective means of protection.
Here in Canada, we have a long-gun (rifle, shotgun) registry. What's next, an edged and blunt object registry, meant to curb knife violence?
Example: Remington Model 700 CDL (gun, bolt action rifle, commonly used for hunting big game)
Example: Colt Canada C7 (gun, the current service rifle of the Canadian Land Forces, based on the American M16, but improved)
