The-Pistol-Composition-by-Earms-h

Often, and could not be otherwise, in this blog appear terms like slider, frame, percussion system, locking lock and a long etc. But do we really know anything about these terms? Who else, who least, we all know what a gun is, but do we know its origin, how it differs from other firearms? I hope with this entry, answer these and other questions, which will certainly help us to increase our knowledge about the weapon.
A gun is called any short weapon of one or more repetitive or semi-automatic shots, except those that have a system of revolving rooms, which we classify them into a group of revolvers. The history of the pistol is closely related to the evolution of mechanics, pistols, military and civilian use and sport. The most important factors for the adoption of small arms were, in addition to mobility and ease of use, concealment and ease of transportation. The achievement of the weapon of repetition was left small for the weapon manufacturers who looked for the transformation of the system of repetition, merely manual, in a semi-automatic.
The origin of the pistol dates back to the 19th century. Joseph Laumann, an Austrian engineer, created in 1892 the first semiautomatic pistol that used ammunition with smokeless gunpowder. It was called Schonberger. In 1893 Andreas Wilhelm Schwarzlose, designed a pistol that was actuated by the movement of the tube, being in 1898 when it manufactured a pistol of semiautomatic operation that, like the previous one, also took its name. The first weapon of this type that reached commercial success was the one invented by the American Hugo Borchardt, well-known also with the name of its inventor. This made its appearance in the year 1893 and was the first that used a detachable loader of its housing in the grip. This pistol can be considered as the precursor of the Luger, Borchardt used a mechanism similar to the joint of a human knee, so that when it was extended and locked it was practically impossible to move it, but once it moved slightly upwards, it opened in an easy and simple way.
Since 1906, names such as John M. Browning and the Colt company in the USA, the Fabrique Nationale d'Armes de Guerre in Herstal (Belgium), and Mauser and Walther in Germany, have united the different systems of differentiation between the types of Pistols, starting a race towards the perfection of operation that has arrived in our days.
OPERATING SYSTEMS
Among the most well-known operating systems are the following:
1. Fixed cannon
Fixed barrel system and recoil lock (Mauser system) In this system, once the firing occurs, the barrel remains stationary attached to the frame while the lock is moved backwards by the force of the gases. This system is used, with exceptions, with low power cartridges. Examples of this system are the Heckler & Koch P9S gun, in which the locking is produced by a system of rollers that do not allow opening until the pressure in the chamber does not drop. Another pistol worth mentioning is P7, also by H & K, in which the delay of the opening of the closure is produced by a gas outlet in the barrel, ie a portion of the gases produced in the combustion of the Gunpowder passes through an orifice to a cylinder whose piston is integral with the slide, preventing the opening of it until the projectile leaves the barrel and the pressure drops.
2. Mobile cannon
Long Rebound Mobile Cannon System The barrel recedes a distance greater than the length of the cartridge. The barrel-closure assembly advances together undergoing a rotational movement thanks to helical-shaped grooves which are in the frame and in which are inserted lugs of which the closure is provided. When the closing barrel assembly reaches the end of its travel, the barrel is unlocked to return to its initial position, to be followed by the closing, which in its movement carries a new inner cartridge of the chamber.
B / . Short recoil mobile cannon system.
ar parts
- Tilting barrel system (Browning-Colt System) In this type, the barrel and the slide retract together until a stop where the barrel is moved downward by fixing and leaving the closure free.
- Straight barrel system The locking assembly is articulated at its middle, and upon firing the barrel-back assembly recedes together until the two cylinders carried by the joint strike against a ramp located in the frame, forcing this part Articulated to effect an upward movement and thus breaking the rigidity of the assembly, separating the barrel from the closure and the latter continuing its movement alone until its stop.
- Cannon Turning System The cannon closing assembly is secured by means of lugs having the latter, which are introduced into the slide and when the movement starts, together driven by the force of the gases, the barrel starts a turning movement by moving out of its anchor and continuing The slide the solo movement.
Pistol Summary:
Slide: It is the carriage or moving assembly that moves on the guides or rails of the frame, allowing the firing. In the great majority it serves as a location for aiming devices, (boost and dash) in others, only carries the rise. It also houses the extractor (of the vanilla), the needle and, in some cases, the devices of the automatic insurance of needle, indicator of assembly mechanism, indicator of cartridge in bedroom and insurance of fin when it is in the slide.
Frame: It is the chassis, armature or container of the firing mechanism, being able to be of steel or plastic of great hardness or alloy, that sustains the structure of the weapon. House the trigger or trigger, transfer rod, detent, disconnector and charger retainer with their respective springs and pins. Also to the ejector or ejector and real pier with its guide, primarily in designs that have hammer, regardless of whether it acts hidden or in sight. The frame can also include the flap insurance, the handle insurance and the loader insurance, as well as the slide retainer, depending on the case.
Magazine loader: It is the device that houses the cartridges with which we will feed the gun during its operation. It can be located on the handle (most) or in front of the guardamonte, and be detachable or fixed. There are dual-row and mono-line chargers.
Barrel: A steel tube, movable or fixed, inside it (bore) may have a conventional scratch (striations) or polygonal.
Recoil spring: It is the spring that returns the slide, which when moving forward will drag a new cartridge, presented by the elevator tile of the magazine, feeding the chamber. They are usually of the helical type, but there are also flat strap models. It can be located under, around or over the barrel. The guide on which it moves in some cases, appears ahead of the slider and serves as a housing for the recoil damper and ramp of "unprotected".
Guarantor (Sear): It is the piece that retains the hammer when we mount or in the intermediate position, in the models that have this type of insurance. In the percussion by shuttle they retain the percutaneous needle by hooking it by its lower spur. When pulling the trigger, the intermediate rod will push or pull the catch, releasing the hammer or the needle, which is retained according to the case.
Disconnector (Disconnector): Its function is to disconnect or interrupt the contact between the catch and the transfer rod of the trigger, during the retraction of the slide, keeping them isolated until it completes its return forward. Its performance is capital, preventing the discharge in bursts and acting as closing insurance.
Ejector or Ejector (Ejector):It detaches the cap from the extraction nail, ejecting it through the open window on the slide during its recoil.
Slide stop: Not all pistols have it. They retain the slider after the last shot, leaving the action open and serving as an exhausted load indicator.
Thumb safety: A finned control, within reach of the thumb, mobilizes the mechanical safety device, which when placed in the frame, can block the trigger or hammer and / or catch, avoiding accidental firing. When it appears on the slide, it locks and / or protects the needle. There are sliding, grip, trigger, loader, etc., according to the particularities of each make or model.
Firing pin safety : Does not release the firing pin, until the trigger is not fully depressed. Today very fashionable.
Magazine safety: Does not enable the trigger system until the charger is not in place. This is a very useful security scheme for profane and clueless people.
Hand safety: Battery puts the trigger when its key or lever accuses the pressure exerted when gripping. It may be on the front or back of the handle
