The most recent supreme court decision DC v Heller upheld the fact that second amendment rights are not unlimited.

> Like most rights, the Second Amendment right is not unlimited. It is not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose: For example, concealed weapons prohibitions have been upheld under the Amendment or state analogues. The Court’s opinion should not be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms. Miller’s holding that the sorts of weapons protected are those “in common use at the time” finds support in the historical tradition of prohibiting the carrying of dangerous and unusual weapons. Pp. 54–56.

this is considerably more limited than the restrictions on attending churches. w.r.t voting, you do need to register ahead of time and in some states you may even have to show a photo ID, though this is under debate.
