Semi-Automatic Gun

By the end of the 20th century, most handguns carried regularly by military, police and civilians were Semi-Automatic, although revolvers were still widely used.

Double-Action Revolver

 This is opposed to "Double-Action" revolvers which accomplish the same end using a mechanical action linked to the trigger pull.

Hand ShotGun

ShotGuns are sometimes preferred for defending a home or business due to their wide impact area, multiple wound tracks (when using buckshot), shorter range, and reduced penetration of walls (when using lighter shot), which significantly reduces the likelihood of unintended harm, although the handgun is also common.

Musket Gun

From the Renaissance up to the mid-1800s, were generally smooth bore firearms that fired one or more ball shot, called Musket.

British Army Gun

The Gun fired 10,000 rounds in 27 minutes. This impressed military leaders from Britain and the following year the British Army purchased the gun. It also adopted the ten-barrel Nordenfelt Machine Gun.

The Machine-Gun

The idea of a Machine-Gun that would keep up a continuous stream of fire attracted inventors early in the development of firearms.

Automatic Shotgun

John Moses was also invented an Automatic Shotgun that would use the expanding gases of a fired shell to relock the gun and make it ready for the next shot.

John Shop

John and his brothers began producing this rifle in their Ogden shop.

Russian Military

The rest of the Western world promptly loaded up their infantry with high-power, new-generation centerfire calibers like the 8mm Mauser, .30-06 Springfield, and the Russian fifty-four-millimeter rimmed cartridge.

Mauser Bolt Actions

Only the Swedes bucked the trend, choosing a 6.5mm cartridge with a mild powder charge for their Mauser Bolt Actions.
