Glock 19 Gen 5 Pistol, 9mm Luger, 4.02 inch Barrel

The Glock 19 Gen 5 chambered in 9mm Luger is a highly popular, striker-fired semi-automatic handgun designed for concealed carry, home defense, and duty use. While standard technical descriptions often round the barrel length to a flat 4 inches. Glock's Marksman Barrel (GMB) replaces the traditional polygonal rifling with a modified barrel lining designed to enhance mechanical accuracy, providing tighter shot groupings out of the 4.02-inch frame.
