Slide - The Glock Slide is the spring loaded part of the Glock semi-automatic pistol that moves back and forth as a pistol is fired. It houses the firing pin/striker and extractor. As the slide moves back, the extractor removes the spent cartridge from the chamber. As the slide moves forward a fresh cartridge is pushed from the magazine into the chamber of the barrel.

2

Barrel - The Glock Barrel is the long metal tube that protrudes from the front of the gun. It contains and directs the pressurized gases that propel the fired bullet in a fixed direction. The barrel also contains the rifling (grooves on the inside of the barrel) which spin the bullet as it discharges from the gun.
