I have been thinking about setting up a home shop to restore / repair antique shotguns. I understand a type 1 FFL is required to do any gunsmithing. What are the ups and downs of having an gunsmith FFL? Is there an FFL just for gunsmithing? Can you actually get an FFL for a repair shop that is in your residence? I do not intend to set up a store and sell glocks. This would be repairs and restorations only.
