This doesn't mean pistols are unnecessary, just that the majority of the troops carrying them are not proficient in their use. The military doesn't take pistol training very seriously because pistols are rarely used on the battlefield.
Beretta m9 a3 how to#
The program was pistol-heavy because, as one instructor put it, "This is the only place in the entire military where you will really be taught how to shoot a pistol." The standards to pass the program were very high, and many of my Green Beret brethren didn't pass because they failed to meet the required shooting standards. As a rule, the larger the silencer, the better its attenuation performance.I once had the good fortune of attending a Special Forces Close Quarters Battle (CQB) training program, which lasted eight weeks.
The silencer reduces only the bang of the high-pressure gases at the base of the bullet, not the concurrent supersonic bang of the projectile when it exceeds about 330 meters per second of the supersonic cartridges. Subsonic cartridges often have batches of special propellants designed to burn close to the muzzle. Every sport shooter is familiar with this fluid equilibrium: the soft cartridge fired from six-inch revolvers for 25-yard disciplines mutates into a rough cartridge with big muzzle-flash when fired from three-inch revolvers.
The actual volume of the shots depends on both the particular load and the barrel length. We generally refrained from doing this, merely tried it out with a load to see if and what happens – the firing noise is a few decibels quieter, it sounds "wet", but further handling of the damper should only take place after it has dripped out. According to the manufacturer, this phenomenon should be able to be turned off by adding a f ew teaspoons of water into the silencer before firing. The "loud-first-shot" phenomenon is also present with the quieter subsonic cartridges. Loudness: the first shot with the silencer Smoke and dirt also billows heavily out of the ejection port of theBeretta M9A3 when fired, a typical side effect of using silencers on semi-automatic firearms. On the other hand, the 113-gr Sellier & Bellot TC FMJ produced the loudest noise of 113 dB without a silencer. This was achieved with the GECO FMJ TC (157 grs). With subsonic ammo, we were able to reduce the shot noise with silencer to the quietest value of 85 dB. Depending on the tested load, between 1.96”/50 and 2.75”/70 millimeters. The suppressor a lways caused a shift in the point of impact. An early example from the Vietnam War was the Smith & Wesson Model 39, which was supplied to the US Navy Seals as the MK 22 with a slide lock – but this pistol became a single-shot gun. A quicker way to reload is to place a catch between the slide and the grip, which is manually operated like a safety. The tinkering with the cable tie creates a single shot gun. The sound with the slide blocked and with unprotected ears is more reminiscent of a short, high whistling sound than a "bang." The whistling sound probably comes from the highly compressed gases exiting the suppressor with the bullet. The gun shoots more quietly with the slide locked by cable ties. The measuring device was placed one meter away at a right angle to the muzzle. We determined about 73 dB for the slide noise only. Under hearing protection, the slide noise seems louder than the shot itself. In addition to the acoustic ones, the differences in kinetic impulses when shooting also stand out, i.e.
Without slide noise is significantly lower. Up! Not pretty and not functional, but test-locked M9A3 slide.
