America's Army/M9 Pistol

Beretta M9 Semiautomatic Pistol M9 Pistol 9mm The M9 is a light weight, semiautomatic pistol manufactured by Beretta and designed to replace the M1911A1 .45 caliber pistol and .38 caliber revolvers. The M9 has redundant automatic safety features to help prevent unintentional discharges. It can be fired in either double or single action mode and can be unloaded without activating the trigger while the safety is in the "on" position. The M9 pistol has a 15-round magazine, and may be fired without a magazine inserted. This weapon can have the hammer lowered from the cocked, "ready to fire," position to the uncocked position without activating the trigger by placing the thumb safety on the "on" position. The 9mm Pistol Program was a Congressionally-directed Non-Developmental Initiative to standardize DoD with NATO and field one handgun for all United States armed services. Beretta of Italy was awarded a multi-year contract for delivery of over 500,000 pistols. The contract award stipulated that production of the weapon must transition from Italian to US production after two years. The US Army is the lead service in this program. The Army began using the M-9 in 1990. M9 pistols feature an alloy frame, a no glare finish, an ambidextrous safety lever, a reversible magazine release, an open top slide, a chamber loaded indicator, and a unique triple safety. M9 Operation The M9 pistol has a short recoil system using a falling locking block. The pressure developed by the expanding gases of a fired round recoils the slide and barrel assembly. After a short run, the locking block is disengaged from the slide, the barrel stops against the frame, and the slide continues its rearward movement. The slide then extracts and ejects the fired cartridge case, cocks the hammer, and compresses the recoil spring. The slide moves forward feeding the cartridge from the magazine into the chamber. The slide and barrel assembly remain open after the last cartridge has been fired and ejected.
