What would determine whether or not one of these firearms falls within this definition or these qualitative criteria is this: When the firearm was originally designed, was it designed to accept, at the time it was manufactured or designed, an oversized magazine cartridge or a cartridge magazine that's capable of holding more than five cartridges? If another cartridge magazine or another magazine was developed not specifically for that firearm but was capable of being used in that firearm, then that firearm would not fall within the definition, unless—I know it's really confusing—there was a cartridge magazine designed for that.
