To the point:
The Second Amendment:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
Of course, the when lawyers enter the fray, words can mean anything. So what do these words mean?
"Militia" is usually a big point of contention. Here's a definition from the current US Code:
Sec. 311. Militia: composition and classes
(a) The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard.
(b) The classes of the militia are -
(1) the organized militia, which consists of the National Guard
and the Naval Militia; and
(2) the unorganized militia, which consists of the members of
the militia who are not members of the National Guard or the
Naval Militia.
That bold part should be drawing attention from the feminists, no? Discrimination?
The founders intended a clear distinction between "milita" the people at large and organized, standing military forces.

"Earlier, in The Pennsylvania Gazette, Feb. 20, 1788, while the states were considering ratification of the Constitution, Tench Coxe wrote:
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 birth-right of an American...The unlimited power of the sword is not in the hands of either the federal or state governments but, where I trust in God it will ever remain, in the hands of the people."
Tench Coxe was America's first Assistant Secretary of the Treasury, Commissioner of Revenue, and Purveyor of Public Supplies. He also was a prolific writer, leaving behind a massive collection of papers relating not only to his involvement with and service to the government of early America, but also to his family's commercial interests, his land dealings, his support of the U.S. Constitution, and his views on the nation's fledgling economy.

Laws that forbid the carrying of arms... disarm only those who are neither inclined nor determined to commit crimes... Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.
--- Jefferson's "Commonplace Book," 1774-1776, quoting from On Crimes and Punishment, by criminologist Cesare Beccaria, 1764

Quotes from the Founders During the Ratification Period of the Constitution
[The Constitution preserves] the advantage of being armed which Americans possess over the people of almost every other nation...(where) the governments are afraid to trust the people with arms.
---James Madison,The Federalist Papers, No. 46.
*****
[W]hereas, to preserve liberty, it is essential that the whole body of the people always possess arms, and be taught alike, especially when young, how to use them; nor does it follow from this, that all promiscuously must go into actual service on every occasion. The mind that aims at a select militia, must be influenced by a truly anti-republican principle; and when we see many men disposed to practice upon it, whenever they can prevail, no wonder true republicans are for carefully guarding against it.
---Richard Henry Lee, The Pennsylvania Gazette, Feb. 20, 1788.
*******
The whole of that Bill [of Rights] is a declaration of the right of the people at large or considered as individuals...t establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of.
---Albert Gallatin to Alexander Addison, Oct 7, 1789, MS. in N.Y. Hist. Soc.-A.G. Papers, 2.
