APS pistol

Gun APS was developed in the late 1940's - early 1950's and constructor. I. Stechkin. Automatic pistol caliber 7,62 mm was the theme of the degree project Stechkin and, after the end of the Tula Mechanical Institute, he development of automatic gun was entrusted to a 9-mm cartridge. Adopted by the Soviet Army in 1951 year, at the same time with a pistol Makarov PM.

APS (Automatic Pistol Stechkin) It was intended as a personal defense weapon of some categories of servicemen and officers, These include for example the crews of tanks and combat vehicles, calculation tools, grenade throwers, officers, acting in active combat zone.

Compared with the PM, APS provides significantly greater firepower and combat effectiveness, due to the larger store and longer barrel tank. Besides, to improve the accuracy of shooting was attached to the gun holster - butt, Adjacent to the hilt. If necessary, from the APS could also fire bursts, at the same time thanks to the retarder rate of fire gun remained more or less on these virtues upravlyaemym.Nevziraya, APS, especially in combination with the standard holster-butt, It was too cumbersome and heavy, he interfered with emergency leaving the military equipment, and the result was soon withdrawn from service and sent to the CA backup storage.

A resurgence in popularity in the MTA began in the early '90s, of - the deterioration of the criminal situation in Russia. Law enforcement authorities have discovered, that the regular pistol PM has insufficient combat effectiveness, and military Kalashnikovs are often redundant power and very cumbersome in the operational work. The best solution would be a sub-machine guns, but their mass production has not yet been, but because various groups of riot police, SWAT and others began to buy decommissioned from the army, but quite capable APS.

Even now, at 2010 year, when there are a variety of sub-machine guns, pistols and more powerful advanced systems, many representatives of law enforcement agencies still prefer Stechkin for their low cost, the wide availability of ammunition, enough good fighting characteristics. true, instead of heavy and regular maloudobnyh wearing holsters-butts are often used homemade or commercial holster open, much lighter and allow for quick retrieval of the gun.

 

Automation MTA acts by free slide recoil. The first option is an automatic pistol in layout resembled "Browning" with the location of the return spring under the barrel. However, serial gun was constructed in the same way, that PM, like cover-gate, streamlined shape, a return spring as the shutter is fitted on the barrel. In general, this is a great design by PM.

Hammer mechanism - trigger, with an open trigger, spiral mainspring and the bent rod trigger, located in the handle, behind the store. The hammer has a military and relief squads. ibid, mounted in the handle mechanism for slowing the rate of fire, comprising a transmission lever and retarder with spring, moving vertically. When the shutter is moving back and forth retarder robs him of the energy, increasing automation cycle time: the introduction of a mechanism to increase the stability of weapons when firing bursts and shooting accuracy. PWhen pressing the trigger raises the trigger bar disconnector, he turns the sear, releasing the trigger. Shutter during the withdrawal lowers uncoupler, bringing it out of engagement with the sear.

The trigger mechanism allows keeping single and continuous fire. Safety lever also serves as a switch fire modes. When automatic fire retardant has the ability to rise to the highest position, but only when the locked shutter position. climbing, Retarder protrusion lifts the shutter rod, and with it, and uncoupler, turning sear. ie. retarder acts as a self-timer. Releasing the trigger bar of the trigger stops interact with moderated. When set to "pr" guard locks the firing pin in the rearmost position, turn locks the trigger sear, and its edge engages the valve frame. Through the interaction of the end of the trigger rod with the protrusion of the trigger shooting can samovzvodom.

It is worth noting, that the concentration in the grip of a number of mechanisms led to the displacement of the center of gravity weapons back. This could degrade accuracy when shooting with one hand, if not great, compared to PM, weight and longer return spring (and therefore more smooth operation automation). As a result, accuracy of firing single shots increased markedly.

Work APS trigger mechanism, like PM, It corresponds to the "descent with a warning", after a free stroke prior trigger stop shooter feels, then to descend a fairly short, a little more effort. The ejector is mounted in the seal groove open.

The slope of the handle - 100 degrees. Separate handle casing attached to the frame with screws. shop 20 rounds, with a checkerboard arrangement of their, It does not project beyond the handle. The side walls have a store window. On expenditure of ammunition feeder store raises the slide stop. Scion gate delay is fired cartridge reflector. APS is also characterized by versatility details: retarder serves the self-timer, action spring - magazine catch spring, the ejector spring - a spring-latch fuse translator etc.

The gate-mounted housing with a cam sector sight regulator, calculated on the firing range 25, 50, 100 and 200 m. Radius dispersion at a distance 50 m - 0,05 m, on 200 m - 0,22 m. Sighting range of fire in 100 and 200 m for such weapons were clearly too high and achievable only when shooting with machine. Total includes design 35 parts, of them 4 in the shop.

Pistols early and late editions differ slightly, mainly parts of the moderator and the handle, shape grooves at the rear portion of the handle for fixing the butt-holster. Carrying a gun is a rigid wooden or plastic holster-butt, Adjoining the conduct continuous fire. OV-applied, as the first sample gun Steckin, performed by type P-35 "Browning High Power" and consists of a body, hinged rigid lid, the tip of the latch for securing the gun handle. The pistol holstered spring fixed on the inner side of the cover. Along with gun worn rubbing screwdriver. Button cover latch and open the gun handle reduce the time its recovery. The holster is transferred to the shoulder strap. 4 spare store is transferred to a haversack
