Glock Factory Original Glock 19 Magazine Black Polymer 9mm Luger 10/rd

These are factory original, drop-free magazines for your Glock 19 handgun. Glock 19 10-round mags are designed to provide flawless function. Factory Glock magazines, including the Glock 19 magazine 10-round factory variant, have a hardened steel insert encased in high-tech polymer. This polymer coating protects the magazine and prevents deformation, even when dropped from a great height.NOTE: GLOCK MAGAZINES CAN BE VERY DIFFICULT TO LOAD WHEN NEW. OFTEN THE LAST ROUND WILL NOT FIT UNTIL THE MAGAZINE HAS UNDERGONE A BREAK-IN PERIOD. IT IS RECOMMENDED THAT THE MAGAZINE BE LOADED WITH ALL BUT THE LAST ROUND AND LEFT FOR A FEW DAYS TO COMPRESS THE SPRING. CYCLING THE MAGAZINE FROM FULL TO EMPTY MULTIPLE TIMES CAN ASSIST IN THE BREAK-IN PERIOD.
