The Ausf.N mounted a short-barrel 7.5 cm Kampfwagenkanone 37 L/24 (7.5 cm KwK 37 L/24) tank gun, previously used on the Panzer IV. It was a low-velocity tank gun that was designed to fire mainly high explosive shells.
If it had to engage armoured vehicles in combat it could fire the Panzergranate armour-piercing AP shell, but it was only effective at short ranges. Later on in the war, crews had the option to load the new 7.5 cm HL-granaten 39 hollow-charge high-explosive anti-tank HEAT projectiles which had a greater effect against tank armour.
