Queen Anne pistol
Queen Anne pistols are a type of flintlock pistol distinguished by the lockplate being forged in one piece with the breech and the trigger plate. They are usually a breech-loading design known as a turn-off pistol. Possibly first made in England〔 See pages 17–19〕 and certainly achieving relatively little popularity elsewhere, they came in fashion in England during the reign of Anne, Queen of Great Britain, hence the name. Though made in all sizes up to carbine, they were usually made in the size range known as coat pocket pistols or coat pistols, easy to conceal on one's person. A small version, known as a Toby or muff pistol, was able to be concealed in a smaller pocket or a ladies hand warmer muff.
Other types of pistol are often referred to as "Queen Anne", but to hopefully improve consistency in nomenclature the term is used here only to refer the "integral breech" lock.
== Design ==
Queen Anne pistols are characterized by the fact that the breech and the trigger plate are forged in one piece with the lock plate, foreshadowing by over 100 years the so called "action" of a modern weapon. A variant, made for muzzle loading with loose shot, had the barrel integral with the breech but in the typical Queen Anne the barrel unscrews with a barrel key or wrench just ahead of the chamber where the powder and ball are placed when the pistol is loaded. The chamber is long and narrow with a cup at the top shaped to fit the bullet (a round lead ball). The user can quickly fill the chamber with black powder and put a bullet on top; the barrel is then replaced, sealing the bullet between its cup and the breech end of the barrel. The bullet is larger than the barrel, so the breech is tapered to compress the ball as it moves forward at the moment of firing to tightly fit the bore. High gas pressure is developed behind the bullet before it is forced into the barrel, thus achieving considerably higher muzzle velocity and power than with a muzzle loader. The barrel was often rifled, which improves accuracy. The system also avoids the need for wadding or a ramrod during loading. It was not successful as a military weapon because in the heat of battle the separate barrel could be dropped during loading. A swiveled, hinged link was designed to allow the barrel to be unscrewed while still remaining attached, but this was evidently not successful. The greatest popularity of the Queen Anne was among civilians as an effective self defense weapon. It was often highly decorated to suit the tastes of the wealthy.
