What kind of weapons did they have in the 1800?

Answer 1

Early 1800s you had smooth bore muskets. Not very accurate, which is why they would line up troops in mass formations and have them shoot at each other. Brown Bess for example.... They also had cannon but those also were not very accurate.

Around the time of the Napoleonic wars you had the introduction of shrapnel rounds.

By the middle of the 1800s they had rifles, which were quite a bit more accurate than the muskets. Sharps rifles could kill at 1000 yards. The Gatling gun was also introduced around 1860.

By the end of the 1800s you had cartridge guns such as the Colt Peacemaker and Winchester rifles. Also the first machine guns.

Look up black powder guns, early cartridge revolvers and rifles.

Answer 2

Probably the sidearm most commonly used by law enforcement officers in the 19th century was the single action revolver. Of course, as the century progressed and technology improved, by the end of the century the single-action revolver was being supplanted by the double-action revolver.
