Percussion caps have been manufactured in various sizes to fit snugly over different sized nipples. Nipples for 4.5mm and 6mm percussion caps. The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition.

The recoil operation is a type of locked-breech action used in semi-automatic and fully automatic firearms. It also uses energy from the combustion in the chamber acting directly on the bolt through the cartridge head, but in this case the firearm has a reciprocating barrel and breech assembly, combined with a bolt that locks to the breech.
Side-by-side shotguns and hunting rifles continued to use side-locks until the advent of the boxlock patented by Anson and Deeley in 1875. Side-lock shotguns have two separate lock plates mounted to the sides of the butt of the gun and not the receiver. In the boxlock, the components of the firing mechanism are contained within the frame of the ...
The new flintlock system quickly became popular and was known and used in various forms throughout Europe by 1630, although older flintlock systems continued to be used for some time. Examples of early flintlock muskets can be seen in the painting "Marie de' Medici as Bellona" by Rubens (painted around 1622–1625). These flintlocks were in use ...
An automatic shotgun is an automatic firearm that fires shotgun shells (thereby making it a shotgun) and uses some of the energy of each shot to automatically cycle the action and load a new round. [1] It will fire repeatedly until the trigger is released or ammunition runs out. Automatic shotguns have a very limited range, but provide ...
An internal hammer cannot be accessed manually during operation. Pistols and shotguns in particular, which have an internal hammer may be referred to as being hammerless. [7] A striker is a type of firing pin operated by the direct action of a spring rather than by a hammer striking the firing pin. Striker-operated firearms lack a hammer.
A snaphance or snaphaunce is a type of firearm lock in which a flint struck against a striker plate above a steel pan ignites the priming powder which fires the gun. [1] It is the mechanical progression of the wheellock firing mechanism, and along with the miquelet lock and doglock are predecessors of the flintlock mechanism .
The term flintlock was, and still is, often applied to any form of friction (flint) lock other than the wheellock with the various forms sub-categorized as snaphaunce, miquelet, English doglock, Baltic lock, and French or "true" flintlock ("true" being the final, widely used form). Strictly speaking, all are flintlocks.
