The Arme S of fist gather the firearms usable with a hand with knowing the Revolver S and the Pistolet S.

Description

An handgun presents an obstruction and a mass thus reduced could be carried permanently without too much embarrassment, but the majority of the ammunition are generally not very powerful and all these weapons remain little présises compared to the weapons of shoulders. A good control of the mode of use of the tail of relaxation is necessary to prevent that the axis of shooting established at the time of the aiming is deviated. Indeed, the hand which maintains the weapon pointed on the target is also that which starts the shooting by a traction of the index. The gunner must thus be able to provide the required effort to the release of the shooting (this traction usually represents between 3 and 5 kg in Double action) without for all this effort dépointe its weapon. This control is all the more difficult to reach that the importance and the proximity of the detonation to the mouth of the gun as well as the violent retreat of certain gauges slow down the rate of shooting and cause an apprehension of the gunner.

The realistic distance from engagement of an handgun hardly exceeds 10 to 15 m and the majority of the combat implying of the police officers oppose distant gunners of less than 3 Mr.

On target, the tested gunners can hope to draw with a certain precision to about fifty meters. An hunting weapon equipped with glasses and implementation under conditions with stress reduced by an operator well trained, lengthened and taking time to aim, will remain precise to 100 m for the moderately powerful gauges and up to 200 m for the very powerful gauges. Beyond, the limits of the mode of pointing of the weapon as well as the weak energy of the ammunition of common handguns degrade too the trajectory.

Functions

One distinguishes several roles allotted to the handgun:

Arms with defense

It is useful only in the event of defense against an adversary. It is in this role that it is carried by the French police officers or the bodyguards.

Arms with 2nd equipment

It is carried by people equipped with a weapon of principal shoulder (generally of the soldiers) and is useful whenever the latter is not available, for example if the weapon is stopped or is with court of ammunition. Few armies arm their soldiers with an handgun with 2nd equipment for reasons with budget, but of the soldiers can buy some individually; it is sometimes the case in the American army. The weapons of 2nd equipment are more frequent in units of special forces, especially in urban environment.

Arms with combat or 1st equipment

It is the principal weapon of its users. This case is rare because of the limitations of this type of weapon. One can quote like example the Groupe of intervention of the national police, but among the groups of combat it is generally a man armed with a weapon of shoulder for the support (pump machine pistol or rifle) where necessary.

Revolver and Gun

Usually confused in works of fiction, revolver and gun distinct handguns indicate.

The Pistolet has a Chambre integrated into the gun or permanently aligned with him (particular case of the gun the French ).

The Revolver, as for him, has a revolving cylinder (" revolving "), called Barrel and containing Room S for loads or individual cartridges.

First handgun allowing automatic recharging, the revolver has some advantages and much disadvantages compared to the semi-automatic Pistolet: of a less capacity, broader, slower to reload, a shooting made slower by Double action always necessary as of the second blow, loss of part of the power of the load (space between the barrel and the gun lets escape from gases). The less reliability of the first Pistolet S is not a relevant criterion today any more.

However the simplicity of the revolver reduces its cost as well as the difficulties presented by its employment and its maintenance. When it is charged, but not armed, no spring tires. It thus constitutes a good solution for the personnel of police force whose practice of the firearms is reduced to the strict minimum. In the event of defective cartridge a simple additional pressure on the relaxation makes it possible to strike the following one whereas a gun then makes necessary an operation of its slide intended to eject it.

Its operation is insensitive with the power of the ammunition drawn or the type of projectile, which is not the case of the gun that a too weak ammunition or of bad quality will often stop. In the case of the shooting of ammunition of strong power, it allows robust weapons and comparatively lighter than a gun to which complex mechanics puts up badly with a high retreat.

In addition it very draws cartouche with the gauge of which the length does not prohibit to confine it and whose developed pressure is never higher than that of the ammunition for which it is intended (a revolver of gauge .357, for example, car some .38). With certain relatively short and standard cases of balls, the catch of stripes after a too long course in the room can however, in this case, to induce a premature wear of the gun.

These advantages weigh rather little vis-a-vis those more determining of the Pistolet and those are essential including in the police force with platinums doubles strict action which allow an elevated level of safety while preserving a simple handling.
