In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties generally can be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for ...
The hammer itself is a metal piece that forcefully rotates about a pivot point. [2] The term tumbler can refer to a part of the hammer or a part mechanically attached to the pivot-point of the hammer, depending on the particular firearm under discussion (see half-cock). According to one source the term tumbler is synonymous with hammer. [3] [4]
Hammerless firearms do not feature an exposed firing hammer or firing “spur”. This feature is easily identifiable in the rear of the weapon's stock and requires the operator to manually “cock” it to arm the weapon. Rifles with an exposed firing hammer were frequently subjected to accidental discharges due to the exposed firing pin.
The second variant, the CPX-2, eliminates the external manual safety that was featured on the CPX-1. The CPX-2 relies on the double action only (DAO) trigger pull, which requires 8.5 to 9 pounds of pressure, to help prevent unintentional discharge. A firing pin spring and low-mass hammer prevent discharge if the handgun is dropped. [2]

Based on the Smith & Wesson Model 2 double-action design, the revolver incorporated an internal hammer and an external grip safety on its back-strap.

Some ...
The Laramie has an automatic safety on the hammer consisting of a sliding bar. After each shot, the bar automatically positions itself between the hammer and the frame, preventing accidental discharge. [2] The bar also blocks the barrel releasing device and the rotation of the cylinder.
