Original sentence: From September 1944, a slightly redesigned mantlet with a flattened and much thicker "chin" design in the lower half of the mantlet started to be fitted to Panther Ausf G models, the chin being intended to prevent such deflections.If a non-penetrating hit bounced downwards off the mantlet's lower section, it could penetrate the thin forward hull roof armor, and plunge down into the front crew compartment.On the Ausf A and Ausf D models, a total of 27 rounds were stored in these forward hull compartment magazines; these were reduced to 18 rounds total on the Ausf G model.Penetrations of this nature could have catastrophic results since the front crew compartment housed the driver and radio operator sitting along both sides of the massive gearbox and steering unit; more importantly four magazines containing main gun ammunition were located between the driver/radio operator seats and the turret, directly underneath the gun mantlet when it was facing forward.The front of the turret was composed of a 100 mm thick cast mantlet, made in the shape of a transverse half-cylinder.The transverse-cylindrical shape of the mantlet meant that it was more likely to deflect shells, but it was discovered that the lower section of the mantlet created a shot trap
