I did a search on a few sites that dealt with Thomas Jefferson and his writings and quotations and did not turn anything up anywhere near what was written above. I did find some other interesting quotations on the subject of RKBA and other liberties. Here goes:
"A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks." --Thomas Jefferson to Peter Carr, 1785. ME 5:85
"The constitutions of most of our States assert that all power is inherent in the people; that... it is their right and duty to be at all times armed." --Thomas Jefferson to John Cartwright, 1824. ME 16:45
"One loves to possess arms, though they hope never to have occasion for them." --Thomas Jefferson to George Washington, 1796. ME 9:341
"I learn with great concern that [one] portion of our frontier so interesting, so important, and so exposed, should be so entirely unprovided with common fire-arms. I did not suppose any part of the United States so destitute of what is considered as among the first necessaries of a farm-house." --Thomas Jefferson to Jacob J. Brown, 1808. ME 11:432
"No freeman shall be debarred the use of arms (within his own lands or tenements)." --Thomas Jefferson: Draft Virginia Constitution (with his note added), 1776. Papers, 1:353
"None but an armed nation can dispense with a standing army. To keep ours armed and disciplined is therefore at all times important." --Thomas Jefferson, 1803. ME 10:365
Malo periculosam libertatem quam quietam servitutem. [I prefer the tumult of liberty to the quiet of servitude.] Even this evil is productive of good. It prevents the degeneracy of government, and nourishes a general attention to the public affairs." --Thomas Jefferson to James Madison, 1787. ME 6:64
"Most codes extend their definitions of treason to acts not really against one's country. They do not distinguish between acts against the government, and acts against the oppressions of the government. The latter are virtues, yet have furnished more victims to the executioner than the former, because real treasons are rare; oppressions frequent. The unsuccessful strugglers against tyranny have been the chief martyrs of treason laws in all countries." --Thomas Jefferson: Report on Spanish Convention, 1792.
