These three all seem to have the same sentiment for having a Federal Concealed Carry for legal gun owners to be recognized in all states. Since the 2nd Amendment is a constitutional right, it should be recognized nationally (reciprocity between all states). Proposal #1 could be the parent proposal since it is very concise and to the point, but could be hashed out to be a little more detailed on the duties of Federal vs State regulation to be sure it makes sense and is not overburdensome for legal owners and get us in the hole some states are already in.
