However, this question deserves answering considering that people are going to be looking for open and operational FFLs. The only brick-and-mortar FFL on the island is A&M Tactical in Middletown near the Coddington Brewery. The next closest gun stores are Sakonnet River Outfitters in Tiverton and Elite Indoor Range in South Kingstown.
There's also the Island Gun Shop in Portsmouth, but he's a home FFL that doesn't maintain a store front AFAIK.
