Glock® 19 Gen 5 9mm Semi-automatic Pistol
With over 20 design modifications from its Gen 4 predecessor, the G19 Gen 5 is proof positive that even the most refined polymer pistol in the world can get better. Among the most notable changes is the Glock Marksman barrel, which now features land-and-groove rifling, a departure from the traditional polygonal rifling of the past. Land-and-groove rifling can provide a boost to accuracy, but, more importantly, it can handle high-volume shooting with lead projectiles.
The Gen 5 preserves the reversible magazine catch of the Gen 4, but goes one step further by incorporating a truly ambidextrous one-piece slide lock. That's a nice upgrade for you lefties out there. The magazine and mag well have also been overhauled. The magazine now features an orange follower so you can visually identify empties, as well as an extended lip for grip. The mag well has been flared for faster reloads. The finger grooves are now gone, and the front strap features a cut-out for extracting the magazine. Bottom line: it's the same Glock you know and love. It's just a little more shooter-friendly now.
