Rifling – Is made by the lands and grooves that engrave the bullet to give it spin as it travels down the barrel. This increases accuracy, think of throwing a spiral with a football.
Chamber – Chambers are meant to house a cartridge, when the revolver is operated, each chamber will turn to line up with the firing mechanism.
Below are the other parts to a double action revolver:
Trigger – When the trigger is pulled, it activates the hammer, which in turn causes the firing pin to strike and fire the cartridge.
Cylinder – Holds cartridges in individual chambers arranged in a circular pattern. Each time the hammer moves to the rear, the cylinder turns and brings a new chamber in line with the barrel and the firing pin.
Cylinder Release latch – Releases the cylinder and allows it to swing out so that cartridges can be loaded and unloaded.
Below are the other parts to a single action revolver:
Single Action – Trigger performs only one action, releases the hammer, firing the pistol
Double Action – Trigger performs two tasks. Cocks and releases the hammer, firing the pistol.
How to unload a revolver:
– Push the cylinder release.
– Swing the cylinder out of the revolver.
– Examine each chamber for ammunition.
– Look into each chamber.
– Feel the rear of the cylinder.
– If cartridges are present, point the revolver up and press down sharply on the ejector rod.

Differences in revolvers:
– Requires manually cocking hammer before pulling trigger
– Reload requires pushing out fired cases one at a time
– Trigger cocks then releases hammer
– Cylinder swings out to allow rapid reloading
