Glock G43X/G48 SLIMLINE 9mm 15-Round Metal Magazine

Metal G43X and G48 SLIMLINE magazines for 9mm Luger. Previously only offered in 10-round polymer, the new 15-round SLIMLINE magazine has a metal, double stack design. The design of the 15-round SLIMLINE magazine includes a radius in the magazine catch recess that allows customers to maintain the standard magazine catch. The magazine itself is the same length with a slightly longer baseplate for better recoil control. May not work with aftermarket metal mag releases.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.
