when were revolvers invented

June 28, 2026

Revolvers, in the recognizable “modern” sense, were invented and made practical in the early 19th century, with key patents in the 1810s–1830s and Samuel Colt’s 1836 design becoming the standard.

Quick Scoop: When Were Revolvers Invented?

If you’re asking “when were revolvers invented?” there are actually a few layers to the answer, because early revolving firearms go back centuries, but the truly practical revolver is much more recent.

Very early revolving guns (1500s–1700s)

In the 1500s, gunsmiths in Europe were already experimenting with matchlock and wheel‑lock pistols that had multiple chambers or barrels which could be rotated to fire more than once without fully reloading.
These were rare, expensive, and often unreliable; think of them as experimental ancestors rather than everyday weapons.

First “true” revolver concepts (1700s–early 1800s)

By the 1700s and early 1800s, inventors had developed guns with a single barrel and a rotating cylinder that brought fresh chambers into line with the barrel.
In 1818, the flintlock revolver was patented (often cited as one of the first clear, documented “revolver” patents), showing that the idea of a rotating cylinder handgun existed before Colt.

Samuel Colt and the modern practical revolver (1830s)

The date most people are looking for when they search “when were revolvers invented” is the 1830s , because that’s when the design became practical and widely adopted.
Samuel Colt’s revolver patent in 1836 is generally credited with creating the first commercially successful, reliable, mass‑produced revolver. His design used a cylinder that rotated as the hammer was cocked, making multi‑shot firing smooth and repeatable without manually turning the cylinder each time.
Colt’s revolvers quickly spread in military, frontier, and civilian use, which is why many sources casually say “the revolver was invented in the 1830s.”

Short, direct answer

Earliest revolving firearms: experimental types in the 1500s–1700s.
First clearly patented revolver designs: late 1700s–early 1800s.
Practical, mass‑produced modern revolver: usually dated to Samuel Colt’s 1836 patent , which is the date most people mean when they ask “when were revolvers invented?”

TL;DR:
Revolving guns existed in experimental form since the 16th century, but the revolver as a practical, widely used handgun was effectively “invented” in the 1830s, with Colt’s 1836 pattern becoming the classic model.
