In the British Empire ( originally in the maritime and hinterland sphere of influence of the East India Company, HEIC, later transformed into crown territories ), mainly in British India, the numbers of guns fired as a gun salute to the ruler of a so-called princely state became a politically highly significant indicator of his status, not governed by objective rules, but awarded ( and in various cases increased ) by the British paramount power, roughly reflecting his state's socio-economic, political and / or military weight, but also as a prestigious reward for loyalty to the Raj, in classes ( always odd numbers ) from three to 21 ( seven lacking ), for the " vassal " indigenous rulers ( normally hereditary with a throne, sometimes raised as a personal distinction for an individual ruling prince ).

Races commence with the firing of the starter's gun.

Once all athletes are in the set position, the starter's gun is fired, officially starting the race.

Upon firing of the starter's gun, the driver and crew person would run up to the boat and swing it around, dragging it to an appropriate depth for launching.

After the starter's gun fires, the driver and crew person may proceed to drag the craft to an appropriate depth before the driver jumps in and starts the motor to begin the race.

On initial firing of the starter's gun, driver and crew proceed to drag the craft to an appropriate depth.

In addition, due to the development of body armor, support personnel required a compact weapon with more penetration than the traditional submachine gun, leading to the development of the personal defense weapon, or PDW, which uses rounds that have better ballistics than simple pistol rounds but less power and range than full rifle rounds.

Since these stock additions retain the short pistol barrel ( as short as 100 mm ( 4 inches )) they are highly restricted under the NFA unless the shoulder stocks are of original manufacture for the gun and the gun has been " delisted " as outlined in links 1 & 2 in the paragraph above, as is the case with so-equipped " Broomhandle " Mausers and Lugers.

An automatic pistol fires one shot per trigger pull, unlike an automatic firearm such as a machine gun, which fires as long as the trigger is held down and there are unspent cartridges in the chamber or magazine.

Most automatic weapons are classed as long guns ( as the ammunition used is of similar type as for rifles, and the recoil of the weapon's rapid fire is better controlled with two hands ), but handgun-sized automatic weapons also exist, generally in the " submachine gun " or " machine pistol " class.

A submachine gun is desirable for its compact size and ammunition capacity, however a pistol round lacks the penetrating capability of a rifle round.

While the dividing line between machine pistols and compact submachine guns is hard to draw, the term " submachine gun " usually refers to larger automatic firearms scaled down from a full-sized machine gun to fire handgun rounds, while the term " machine pistol " usually refers to a weapon built up from a semi-automatic pistol design.

The Steyr TMP | Steyr Tactical Machine Pistol, classified as both a machine pistol and a compact submachine gun

While the term submachine gun usually refers to an automatic firearm larger than a pistol, several weapons are classed in both categories.

In addition to serving as backup guns, revolvers still fill the specialized niche role as a shield gun ; law enforcement personnel using a " bulletproof " ballistic shield ( Gun shield ) sometimes opt for a revolver instead of a self-loading pistol, because the slide of a pistol may strike the front of the shield when fired.

A submachine gun ( SMG ) is an automatic carbine, designed to fire pistol cartridges.

It combines the automatic fire of a machine gun with the cartridge of a pistol.
