If your referring to the "muzzle loading" musket/rifle; the US Army's last offical use of that weapon was the US Civil War. In 1866 the US Army adapted the metallic cartridge 50-70 single shot rifle. Then in 1873, the US Army got rid of the 50-70 and adapted the 45-70 Government cartridge. Both sides used the musket/rifle in the Civil War. A muzzle loading musket could be either smooth bore or rifled. However, generally speaking, whenever a man used the term "musket", it was usually presumed to be a smooth bored weapon.

A pistol would generally be considered a weapon with a relatively short barrel length like a handgun, whereas a musket would be a long barreled weapon more like a rifle.
