What is a double action revolver?

A double action revolver is a type of handgun in which the trigger both cocks and releases the hammer in one smooth motion, allowing for quicker firing compared to single action revolvers that require the hammer to be manually cocked before each shot. Double action revolvers are known for their simplicity, reliability, and ease of use, making them popular among both law enforcement and civilian shooters.

Double action revolvers often have a swinging cylinder that holds the ammunition and rotates to align the next round with the barrel for firing. They typically have a cylinder release latch that allows for quick and easy reloading, and most models feature a fixed front sight and an adjustable rear sight for improved accuracy.

Common calibers for double action revolvers include .38 Special, .357 Magnum, and .44 Magnum, with varying barrel lengths ranging from 2 inches for concealed carry to 6 inches for target shooting or hunting. Some models also feature a double action/single action mechanism, allowing the shooter to manually cock the hammer for a lighter trigger pull in single action mode.

Overall, double action revolvers are valued for their versatility, ruggedness, and user-friendly design, making them a popular choice for shooters of all skill levels.
