The phrase "well-regulated" was in common use long before 1789, and remained so for a century thereafter. It referred to the property of something being in proper working order. Something that was well-regulated was calibrated correctly, functioning as expected. Establishing government oversight of the people's arms was not only not the intent in using the phrase in the 2nd amendment, it was precisely to render the government powerless to do so that the founders wrote it.
"I ask, Sir, what is the militia? It is the whole people. To disarm the people is the best and most effectual way to enslave them." - George Mason Co-author of the Second Amendment during Virginia's Convention to Ratify the Constitution, 1788
"A militia, when properly formed, are in fact the people themselves …" - Richard Henry Lee writing in Letters from the Federal Farmer to the Republic, Letter XVIII, May, 1788.
The power of the Sword, say the minority of Pennsylvania, is in the hands of Congress. My friends, and countrymen, it is not so for the powers of the sword are in the hands of the yeomanry of America from sixteen to sixty. The militia of these commonwealths, entitled and accustomed to their arms, when compared with any possible army, must be tremendous and irresistible. Who are the militia? Are they not ourselves? Is it feared, then, that we shall turn our arms each man against his own bosom? Congress have no power to disarm the militia. Their swords, and every other terrible implement of the soldier, are the birthright of an American. The unlimited power of the sword, is not in the hands of either the federal or state government, but, where I trust in God it will ever remain, in the hands of the people." - Tench Coxe, Penn Gazette, Feb. 20, 1788.
"...but if circumstances should at any time oblige the government to form an army of any magnitude, that army can never be formidable to the liberties of the people, while there is a large body of citizens, little if at all inferior to them in discipline and use of arms, who stand ready to defend their rights..." - Alexander Hamilton speaking of standing armies in Federalist Papers 29
