Modern Firearms - Breda M1935 PG rifle
The Model 1935 or PG (Peso a Gaz, gas-operated) rifle was developed during early 1930s by famous Italian company Societa Meccanica Ernesto Breda. Originally designed to fire standard Italian rifle ammunition of the period, the 6.5x52 Carcano round, in semi-automatic mode, it was later redesigned to fire somewhat more powerful 7x57 Mauser ammunition with select-fire capability. The 6.5mm semi-automatic version, according to some sources, was pressed into Italian service in limited numbers in around 1943-44. The 7mm select-fire version was developed under contract from Costa Rica
, and about 400 automatic Breda PG rifles were produced for Costa Rican government. Breda M1935 PG rifles were somewhat heavy, of complicated design, and expensive to make. Historical importance of these rifles is that Costa-Rican Breda PG automatic rifles were probably the first weapons to incorporate burst limiting mechanisms, which, when engaged, automatically cut the bursts of automatic fire after just 4 rounds, in an apparent attempt to conserve ammunition.
