text: Single-shot Single-shot handguns were mainly used during the era of flintlock and musket weaponry where the pistol was loaded with a lead ball and fired by a flint striker, and then later a percussion cap. The handgun required a reload every time it was shot. However, as technology improved, so did the single-shot pistol. New operating mechanisms were created, and some are still made today. They are the oldest type of pistol and are often used to hunt wild game. Additionally, their compact size compared to most other types of handgun makes them more concealable.
  Revolver
  With the development of the revolver, short for revolving pistol, in the 19th century, gunsmiths had finally achieved the goal of a practical capability for delivering multiple loads to one handgun barrel in quick succession. Revolvers feed ammunition via the rotation of a cartridge-filled cylinder, in which each cartridge is contained within its own ignition chamber and is sequentially brought into alignment with the weapon's barrel by an indexing mechanism linked to the weapon's trigger (double-action) or its hammer (single-action). These nominally cylindrical chambers, usually numbering between five and eight depending on the size of the revolver and the size of the cartridge being fired, are bored through the cylinder so that their axes are parallel to the cylinder's axis of rotation; thus, as the cylinder rotates, the chambers revolve about the cylinder's axis.
