Another difference between the C-9 and C-9 Comp. is the barrel length. Its 4 in (102 mm) barrel is 1 ⁄ 2 in (12.7 mm) longer than its sister weapon's providing for better accuracy and balance. The compensator and extra bulk also increase the weight.
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that suppresses the blast created when a gun (firearm or airgun) is discharged, thereby reducing the acoustic intensity of the muzzle report (sound of a gunshot) and jump, by modulating the speed and pressure of the propellant gas released from the ...
The hammer is concealed within the slide (also similar to the Sauer) with a protruding pin at the rear of the slide as a cocking indicator. The operating spring surrounds the barrel, allowing for a lower bore axis than pistols such as John Browning's M1911 that have the operating spring below the barrel. A manual firing-pin safety is located at ...
Upgrading the M1911 would cost more than it was worth, so it was decided that they would select an entirely new design. A request for quote was for a system that included a pistol, suppressor, and laser aiming module. The pistol had to be corrosion resistant, have a high mean rounds between failures (MRBF), and be able to serve as a primary weapon.
The XM177 Commando variant of the M16 rifle used a unique flash suppressor sometimes called a flash or sound moderator for its 10-inch barrel. This device is 4.2 inches long and was designed primarily as a counterbalance measure, as the shorter barrel made the weapon unwieldy. [ 6 ]
The safety/selector lever is located on the right hand side and allows for semi-automatic single shots and fully automatic fire at the rate of 800 rounds per minute. The effective range of the PP-91 is between 50-100m. The weapon uses a diopter sight and allows for the use of a laser sight and a suppressor.
Animation of the Vickers muzzle booster operation, showing the expanding gases pushing the barrel to the rear relative to the cooling jacket. A Vickers-type muzzle (or recoil) booster, the "typical" type, consists of two parts: a flared "cup" on the muzzle of the barrel, and a perforated tube around the end of the muzzle, attached to the main body of the weapon.
