Brief History of the Glock 19 Series

The Glock 19 was first introduced in 1988 as a more compact version of the Glock 17. Its smaller size and reduced weight made it an ideal choice for concealed carry while maintaining a high magazine capacity. The G19 quickly gained popularity among civilians, law enforcement agencies, and military units around the world.

Over the decades, Glock released multiple generations of the G19, each featuring incremental upgrades based on user feedback and technological advancements. The Gen 3 brought accessory rails and finger grooves, while the Gen 4 improved grip texture and introduced interchangeable backstraps.

In 2017, the Glock 19 Gen 5 arrived with notable design changes, including the removal of finger grooves, the addition of ambidextrous controls, and the Glock Marksman Barrel for improved accuracy. This evolution reflects Glock’s commitment to refining its products to meet modern demands. Today, the Glock 19 remains one of the best-selling pistols globally, valued for its reliability, ease of maintenance, and adaptability.

What’s New in the Gen 5 Model?

The Glock 19 Gen 5 introduced several updates that distinguish it from earlier versions. The most noticeable change is the removal of finger grooves, providing a more natural grip for shooters with different hand sizes. The addition of an ambidextrous slide stop lever allows both left- and right-handed users to operate the pistol more efficiently.

Another major enhancement is the Glock Marksman Barrel (GMB), designed with improved rifling to increase accuracy. The slide features a tough nDLC (Diamond-Like Carbon) finish for better resistance to wear and corrosion. A slightly flared magwell has also been added, making reloads faster and smoother, especially under stress.

Internally, Glock redesigned the firing pin safety and extractor for improved reliability. The trigger mechanism has been tweaked to deliver a smoother pull and cleaner break. Together, these updates make the G19 Gen 5 not only more user-friendly but also more durable, accurate, and dependable in various shooting environments.
