Parts of a Revolver, Names, Functions & Diagram

Overview of Revolver Anatomy

A revolver is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers for firing. Each chamber contains a single cartridge because most revolvers hold up to six rounds of the cartridge before needing to reload. Revolvers are also commonly called six-shooters. Out of all firearms, revolver use is typical in the police force. All parts of a revolver are precisely manufactured to make it more efficient. Limited government companies have permission to manufacture revolver parts and assemble them. We will go through all these parts, locations, and names with a diagram.

Parts of a Revolver

This video tells us all parts of a revolver, their names & functions.

Barrel

A barrel is a straight metal cylinder of high-strength materials. Its length and diameter/caliber (internal and external) depend on the type of revolver and manufacturer.

Barrel material should withstand the high pressure and temperature generated due to the gunpowder explosion.

Cylinder

The cylinder is the cylindrical rotating part of a revolver, containing multiple chambers, each capable of holding a single cartridge. The cylinder rotates around a central axis in the revolver’s action to sequentially align each individual chamber with the barrel bore for repeated firing.

Generally, 6 chambers are present in the cylinder. Each time the gun is cocked, the cylinder indexes by one chamber.

Frame

The frame is the basic revolver metallic construction which holds the all-other parts of the revolver. Generally, the material of the frame is steel, aluminum alloys, or polymer.

Muzzle

The muzzle is the end of the barrel from which the bullet exits. Maintaining its accuracy is more important as its accuracy decides the final path of the bullet.

If the accuracy is not correct, propellant gases may spread unevenly, and the bullet may deflect from the pathway. The end of the muzzle has a thread to attach any accessories.

Sights

Sights are the alignment markers for the accurate aiming of the weapons. There are two sights present in the rifle. The rear sight is near the shooter’s eye, whereas the front sight is present near the muzzle. The shooter can see the aim from the rear and front sights and align with the aim to shoot.

Hammer

The hammer is a part of a revolver, which is the percussion cap/primer or a separate firing pin strike on the projectile to ignite the explosive and fire the bullet. Shooters have to manually cock the hammer before firing. It is a metal piece that forcefully rotates about a pivot point.

Trigger

The trigger is the actuating mechanism that allows the hammer to strike the projectile. It is a small curved metallic part where we put out a finger to operate.

Trigger Guard

It is a protective edge that surrounds the trigger of a gun to prevent unwanted contact to avoid accidental discharge. Trigger guards present in every gun.

Grip

The grip was present behind the trigger, and the shooter put his hand on the grip to trigger the revolver. It has a rubber coating and knurling to get stability during shooting.

Cylinder Release

The cylinder release is a small lever present on the left side of the double-action revolver and on the right side of the single-acting revolver. Its function is to unlock the cylinder to swing out from the frame to load and unload the bullets.

Top strap

The top strap is the part of the frame that goes over the top of the frame.

Revolvers Cylinder Parts

Crane/yoke

The yoke mounts on the frame, and the cylinder rotatably mounts on the yoke.

Chambers

Chamber is the cylindrical cavity in the cylinder where the cartridge gets inserted. There is a minimum of 6 chambers generally present in the cylinder. It varies as per the manufacturer.

Extractor Star

It is a star shape mechanism that pushes cartridges out of the revolver cylinder.

Ejector Rod

The ejector rod helps the shooter to eject the cartridge casing after the fire. In a single-acting revolver, one cartridge ejects at one time, whereas in a double-acting revolver, all cartridge ejects from a cylinder.
