There is no comma after militia.
In the original hand-written copy of the Bill of Rights prepared by William Lambert, it is.
As ratified by the States and authenticated by Thomas Jefferson, then-Secretary of State:
A well regulated militia being necessary to the security of a free state, the right of the people to keep and arm bears shall not be infringed.
