In the Wiki page for the Macchi C.202 Folgore it says some pilots removed guns to save weight. Is there any other sources out there of other pilots doing the same thing?
Initially, all the armament was fitted within the nose of the Macchi. Ammunition carried was up to 800 rounds (standard: 700 rounds). An additional pair of Breda 7.7 mm (.303 in) machine guns was fitted in the wings in the VII series onward, but these, along with 1,000 rounds of ammunition, added 100 kg (220 lb) to the aircraft's weight. Consequently, they were typically removed by pilots to save weight, since they were relatively ineffective against most enemy aircraft in 1942.[20] A synchronizing unit allowed the nose guns to fire through the propeller disk, but with a 25% loss in ROF (Rate of Fire).[21] A "San Giorgio" gun sight, a reflection unit, was also fitted in the cockpit.
