Correct.
The Constitution is a charter of conferred powers, powers the people possess and lent to government. All not conferred is retained by the people and that includes the individual citizen's right to keep and bear arms, free of any conditioning or qualification. No power was ever granted to government to impact the personal arms of the private citizen so none exists -- the people retained all aspects of the right to arms . . . There was nothing for the government to "give back" or grant to the citizen via the 2nd Amendment because the government can not give what it never had.
The Supreme Court has affirmed this principle multiple times over the last 135 years for the citizen's right to keep and bear arms.
Presser is typical:
"[T]he right of the people to keep and bear arms is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence"
PRESSER V. ILLINOIS, 116 U. S. 252 (1886)
So, the act of "interpreting" the words of the 2nd Amendment (upon which the right does not depend) to impart conditioning, qualifications or any other outward restriction on the citizen's right to arms, is completely illegitimate.
