Sez you.
I would argue that the INTENT was for a "well-regulated militia" (now where did that come from??) take the place of the standing armies as they existed in Europe at that time, something the Founders did write about.
Nowhere does the 2A address the "quality" or "grade" of a weapon, as QA/QC was hit-or-miss in the days of hand-made muskets. As such, it's well within the right of Congress to restrict firearms to nothing more than a hand-made musket. That would not violate the 2nd.
I would have to disagree. The muskets of the day were state of the art. Many people also had 'handguns' and personal edged weapons. The amendment references 'the right of the people to keep and bear arms' without specifying type, quantity or capabilities.
