> Basic Revolver
A basic revolver consists of three components:
- Grip Panels - usually composed of wood, rubber, or molded plastic and are attached to the lower portion of the frame.
- Trigger Guard - protects the trigger to reduce the possibility of an unintentional firing.
- Rear sight - used with the front sight when aiming.
- Backstrap - rear vertical portion of the frame that lies between the grip panels.
- Bore - the inside of the barrel.
- Rifling - spiral lands and grooves cut into the bore. The rifling imparts a spin on the bullet that stabilizes it in flight.
- Muzzle - font end of the barrel.
- Caliber - distance between the lands. Measured in decimal fractions of an inch or in millimeters.
- Front sight - used with the rear sight in aiming.
- Trigger - when pulled it activates the hammer.
- Hammer - causes the firing pin to strike and fire the cartridge. The hammer spur is the thumb-gripping surface on the hammer.
- Cylinder - holds ammunition in individual chambers that are rotated into firing position by the action of the trigger or hammer.
- Cylinder release latch - releases the cylinder and allows it to swing out for loading and unloading.
- Ejector - removes cartridges from the cylinder when activated by the ejector rod.
- Ejector rod - activates the ejector.
