The demands of wartime production resulted in a redesign of the Beretta Model 38. For mass production on the large scale demanded, the Beretta 38/42 was made slightly smaller and lighter than the original Model 38A. As many parts as were practical were made of steel stampings rather than machined parts. The perforated barrel cooling jacket of the 38A was eliminated, though eight longitudinal flutes were cut into the barrel. The fluting increases the surface area of the barrel, increasing the rate of cooling from the air circulation and heat radiation. An integral compensator was machined as two slots in the top of the barrel muzzle. Post 1944 construction eliminated the cooling flutes resulting in a smooth barrel.
The internal mechanism of the Model 38/42 had been modified with the mainspring more enclosed in a tubular container, the rear of which extends out slightly from the back of the receiver. The receiver of the weapon was now produced of sheet metal with the magazine well being a separate construction and welded in place. The cocking handle was redesigned to include a dust cover that helps seal the action, a result of the Italian Army’s action in the sands of North Africa. The cocking handle does not reciprocate when the bolt moves.
The dual trigger system acts as the selector for full and semiautomatic firing. Pulling on the front trigger results in semiautomatic firing. Pulling on the rear trigger allows the weapon to fire on full automatic. Serrations on the rear trigger allow it to be recognized by feel. These changes made the Beretta 38/42 much easier to mass produce as well as lowering the cost of production considerably. As the Beretta facilities were located in Northern Italy, production of the 38/42 continued under German occupation after Italy fell to the Allies.
