Answer:

Modern-day handguns are produced of a particular blueprint that determines their specifications. One major characteristics trait of this specification is known as Rifling.

Rifling is an act or process of making the grooves in a rifled cannon or gun barrel. The system of grooves in a rifled gun barrel in which one side of the groove is made deeper than the other side to facilitate loading with shots having projections is enough to determine what brand/model of specific weapon is being used.
