The main armament of the M41, the M32 gun, was the first cannon with an evacuator, which was capable of preventing poisonous gas leaking into personnel cabin. Additionally, its T-muzzle break was able to conduct gas to both sides, in order to provide for further firing. Although it only had a caliber of 76.2 mm, the M32 was even more powerful than its 90 mm contemporary.

The Continental AOS-895-3 gasoline engine of M41/M41A1 suffered from limited mileage, later developed M41A2 and M41A3 thus adopted newer AOS1-895-5 engine. An engine driven component for the turret was also added, resulting in the exhaust pipe to extrude from the right chassis, which had become its most distinguishing characteristic in appearance. Additionally, the gun of the M41A3 had 65 reflings, where as the previous versions only had 57. Together with modifications on the interior, the M41A3 became the most produced version among the M41 series, and was serving the Army of the Republic of Vietnam in large quantity during the Vietnam War. The M41 can be deployed with transportation aircraft. In addition to its service in the US Army, the M41 is still in service with many countries after continuous improvement and service life extending modifications.
