Not at all. Alexander Hamilton was quite clear what they meant by a militia in the
Federalist Papers #29. If you are not familiar with them, they were a series of pamphlets written to persuade people of the time to support the new Constitution. They were intended to be a relatively small body of trained soldiers controlled by the states, who could be called out when needed. That's essentially what our National Guard is. Since the Militia is living their lives when not called out, and they had personal weapons that they were familiar with and maintained, hence the "keep and bear arms" passage.
They were concerned about a tyrannical central government, which they had just fought a war to get rid of a few years previous. So they didn't want the new federal government being created by the Constitution to ever take away the local militia's and citizen's guns. Hence the larger phrase "the right of the people to keep and bear arms shall not be infringed". Plenty of people besides the Militia had guns for various reasons - hunting, defending against native attacks, the possibility of the British returning (which in fact they did 24 years later). The Militia were the first line of defense, but the general body of able-bodied men with weapons could back them up if necessary.
(This of course was long before women's rights and modern weapons that no ordinary individual can afford)
