State v. Rardon
In State v. Rardon, 185 Wis. 2d 701, 518 N.W.2d 330 (Wis. App. 1994), the Wisconsin Court of Appeals addressed the issue of "whether the possession of a disassembled and inoperable firearm by a person previously convicted of a felony is a violation of Wisconsin statute" where the applicable statutory definition provided that "firearm means a weapon that acts by force of gunpowder." Id. at 703 & 705, 518 N.W.2d at 330-31 & 331-32.
The court specifically noted that many of today's weapons are easily taken apart and concluded that a "firearm is appropriately defined as a weapon that acts by force of gunpowder to fire a projectile irrespective of whether it is inoperable due to disassembly." Id. at 706, 518 N.W.2d at 332.
