Not sure what you are asking. In relation to guns, FFL stands for Federal Firearms License, which is a license to sell handguns, and generally speaking, has nothing to do with being a police officer. That said, in the U.S. police officers can carry a handgun just about anywhere, especially if it is while discharging official duty, or while on duty. Also, under federal law HR218, police officers can carry almost anywhere in the U.S. even when they aren't in their home state, but they must abide by local restrictions.

We cannot accurately answer this question without you specifying what state/jurisdiction you're in. Refer to your state laws regarding handguns and ensure that you are meeting all of the legal requirements. If you are in accordance with state law, then it is up to the particular business. I suggest you review the business's policy, and bring this up to your supervisor/manager. If the business has no objections, then you're certainly allowed.
