Reliability and simplicity have made GLOCK® G19 Semi-Auto Pistol one of the most widely used sidearms in law enforcement worldwide. The G19 is a mid-size pistol, shooting the 9x19mm pistol cartridge (9mm Parabellum), a standard military round that’s easy to find ammo for anywhere. The GLOCK 19 is a short-recoil operated, striker-fire semi-automatic pistol. The Safe-Action trigger system makes shooting in stressed situations infallible. The main frame of the GLOCK pistol is constructed of high-strength polymer that is resistant to shock, caustic liquids, and temperature extremes. The milled steel slide and the barrel are treated with matte black Tenifer finish for extreme resistance to wear and corrosion. The Tenifer treated steel and polymer frame make the pistol impervious to corrosion caused by perspiration and humidity when carried close to the body, or kept in a holster for extended periods of time. The slide cycles on 4 hardened steel guide rails within the frame. An integral accessory rail in front of the trigger guard allows for the attachment of aftermarket tactical flashlights or laser sights. The white-dot front sight and the white-bracket rear sight provide rapid acquisition in dim lighting situations. The rear sight is dovetailed into the slide and is drift adjustable. GLOCK pistols fieldstrip easily without the use of tools. The GLOCK G19 Semi-Auto Pistol is an ultra-reliable handgun that is easy to learn how to operate and maintain, making it an ideal choice for self-defense, whether it be for concealed carry, at home, or on duty. The model G19 comes with two standard 15-round magazines, or two 10-round magazines that comply with various city or state restrictions on magazine capacity.
