TJ (father of my alma mater UVa) did say plenty on the RKBA, such as:
"When the govt fears the people, there is freedom. When the people fear the govt, there is tyranny."
"No free people shall ever be debarred the use of guns."
"The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in govt."
