The factory floor at Beretta was I'd say 2/3rds capacity when I was there a few years ago. The problem I would see with them trying to expand production there wouldn't be machines to make the PARTS but a couple production steps would be a hold up as there was a limited number of people with the right skill sets and their space was almost at capacity. One spot was where they heat treated the barrels and where they did the finishing. Expanding those areas would be difficult as it would impact other areas, namely the QC/proofing area and gunsmiths.
