Based on an original Austrian design (by Bohler), the Cannone da 47/32 M35 was an Italian licensed-produced, local copy of the anti-tank/infantry field gun for the Army. It fired a 47mm HEAT (High-Explosive, Anti-Tank) and AP (Armor-Piercing) projectile capable of penetrating light-class vehicles. The gun proved so efficient that it made up the main armament of the guns seen in the Autoblinda AB 41 series armored car, the Carro Armato M15/42 Medium Tank and the Semovente 47/32 Self-Propelled Gun (SPG) platform.
The M35 was given a conventional artillery piece arrangement, mounting the 47mm caliber with 32-caliber-lengths gun barrel (hence the "47/32" in the designation) to a mounting system. The recoil mechanism was integrated. Split-trail tow arms were also used to take on some of the recoil forces. The tow arms then came together when the weapon system was to be moved by vehicle. In its combat stance, the weapon weighed 610lbs. Its travel weight was listed at 700lbs. Overall length of the system was 5 feet, 6 inches.
The mounting hardware allowed for an inherent elevation range of -15 to +56 degrees with a 62-degree limited traverse (using the supplied hand wheels). Muzzle velocity of the exiting projectile was 2,065 feet per second when using the standard AP round (the HEAT round measured a much controlled 820 feet per second). Maximum range was out to 7,700 yards and armor penetration of 58mm could be reached out to 100 meters with the AP projectile.
Initial production marks (Mod.35) featured semi-pneumatic disk-type wheels. It was not until 1939 that a slightly new mark appeared, this as the Mod.39 with a revised wheel design.
Captured Italian guns (following the 1943 Italian September surrender) in German service were designated as 4.7cm PaK 177(i) - the lowercase "i" to indicate their Italian origins.
