Here's where my rub has always been. Where is this determination, for guns not on the list, stated? For non-listed guns, the large capacity roster says, "weapons equipped with a large capacity feeding device" It does not say, "weapons originally equipped with a large capacity feed device." The very existence of the list that determines which guns are considered large capacity implies that guns not on the list (and not subject to their specific listed additions) are NOT large capacity.
Again, I follow what the lawyers say in practice, but I still would like somebody to show me the evidence.
I'll agree with you. That's why I tend to lean on the side of caution.
