Hammer Fired
In the world of modern firearms which use centerfire cartridges, there are two major types of mechanisms used to trigger the cartridge primer. One uses a hammer and another uses a striker. Therefore, mechanisms that use a hammer are called hammer-fired and the ones that use a striker are called striker fired. As you can guess, each mechanism has its own group of supporters.
In a hammer fired mechanism, the hammer is a heavy piece that is allowed to rotate about a pivot point. When the hammer is cocked, it compresses a spring. When the trigger is released, the spring pushes the hammer and forces it to rotate forward. The end of the hammer strikes the back end of a firing pin, which is a thin steel pin with a hardened tip. The front end of the firing pin strikes the primer of the cartridge, thereby detonating it. The image below shows how this works.
In some revolvers, the firing pin is attached to the hammer directly.
