Los Angeles police officers have been ordered to stop using Glock 21 semiautomatic handguns after reports that the weapon misfired dozens of times during training and firearms qualifying sessions, reports the Los Angeles Times. The .45-caliber gun, favored by law enforcement for its power and accuracy, has been purchased by 1,600 of the roughly 9,100 Los Angeles Police Department officers for on-the-job and personal use.
Police officials took the unusual step of ordering the gun out of service after they became aware of problems with “light strikes,” which occur when a loaded cartridge is hit by the firing pin but is not hit hard enough to discharge a bullet. Officials expressed concern that the gun could malfunction at a crime scene, leaving a responding officer unprotected. The Austrian arms company replaced trigger bars in all Los Angeles police Glock 21s. The replacement stopped misfires in some weapons, but the problem appeared for the first time in others. The department received more than 20 complaints in several days, and department armory personnel noticed unusual wear in the weapons.
