Just to add a little bit of clarity, the original design is really looking at the specifications of that firearm. Within those original specifications of the firearm, the manufacturer or the designer will indicate the intent and what magazines are intended for that firearm. They could identify a two and a four. They could identify many. Sometimes they will identify one. That doesn't mean there are no other cartridges for that firearm. This element of the definition is really to look at the intent of the manufacturing of that firearm.
In that specification, was it specified for a 20-round? Regardless of whether it could take a two or a four, what was the intent of the specifications? That's my understanding of the fourth element in that definition.
