Revolver Terminology

I wanted to illustrate the basic components of a revolver, and decided to use my very old .38 to do so. This revolver isn't in the best of shape, but it has great sentimental value to me. Despite its age and appearance, it shoots fairly well.


Revolvers never jam, have stood the test of time as the first "personal" handgun, and can still be found everywhere. New revolvers still have the same parts and components this model has.



Starting from the top left going clockwise: The Front Sight is used in conjunction with the rear sight to align the firearm on target. The Barrel guides the bullet as it is discharged toward the intended target. The Rear Sight is used in conjunction with the front sight to align the firearm on target. The Hammer is used to strike the firing pin and discharge the cartridge in the firearm.

The Thumbpiece is used to release the cylinder from the frame to reload the firearm. The Frame is the firearm's framework. The Trigger discharges the weapon. The Cylinder holds the ammunition for the firearm and revolves the cartridges as they are used to the next round. The Extractor Rod is used to eject spent cartridges once the cylinder is open.

Looking at the other side of the revolver, you can see the Thumbpiece is not available. Like a magazine release on modern firearms, the thumbpiece is usually on one side only.


Revolvers are still outstanding carry pieces, and are great "first time" firearms. People who have problems with operating a slide on a modern automatic should consider a revolver because of their easier operation.

On a quick side note... in Texas, if you take your concealed carry certification test with a revolver, your license will restrict you to carrying a revolver only. If you take your concealed carry certification test with an automatic firearm, your license will allow you to carry both an automatic and a revolver.
