PI and armed guard are different. An armed guard may only carry on duty and within the assigned area of duty (ie...not to and from work or go shopping, etc).
A PI is different, where there is not really an assigned post (so may carry throughout the State). Also, a PI can be considered on-duty at any time. Many PI's are self-employed.
