Chambered in 9 mm Luger the G48 Rail features a compact Slimline frame with a slim mounting rail and a black slide with nDLC finish as well as a 10-round magazine capacity making it ideal for concealed carry. The G48 Rail is of similar length and height as the G19 but the width of the pistol is reduced for increased concealability and better carrying comfort. The frame features the GLOCK Mounting rail slim for mounting tactical accessories and incorporates elements of the Slimline series such the short trigger distance, a frame with a built-in beavertail, a reversible magazine catch and the incredibly accurate, match-grade GLOCK Marksman Barrel (GMB) of the Gen5 series. The G48 Rail also features precision-milled front serrations.
