The initial model of the Beretta 38A had a number of features that were dropped rather quickly once wartime production became a priority. Specifically, they included a lockout safety switch for just the rear full-auto trigger. This was in place primarily for police use, in which the guns were intended for semiautomatic use except on dire emergency (and the first batches of 38As in Italy went to the police and the Polizia dell’Africa Italiana). The first version of the 38A also included a bayonet lug to use a version of the folding bayonet also used on the Carcano rifles. This was a folding-blade bayonet, and the model for the 38A replaced the rifle muzzle ring with a special T-lug to attach to the muzzle brake of the SMG. These bayonets are extremely scarce today, as they were only used for a very limited time.
