Glock 19 vs 48: Which Handgun is Best for You?

What’s the difference between the Glock 19 and Glock 48? The Glock 19 offers higher capacity and a slightly thicker frame, while the Glock 48 features a slimmer design for easier concealment with a single-stack magazine.

The Glock 19 is a compact workhorse, balancing firepower and shootability for both concealed carry and range sessions. The Glock 48, by contrast, is engineered for discretion—streamlined for all-day carry without excess bulk. Both maintain Glock’s hallmark reliability and intuitive controls.

If your priority is capacity and versatility, the Glock 19 remains a leading choice. If concealability and comfort take precedence, the Glock 48 deserves your attention. The decision comes down to how you carry and what you value most.

Similarities Between Glock 19 vs 48

Both the Glock 19 and Glock 48 are built from the same Glock DNA: striker-fired, polymer-frame 9mm pistols using Glock’s Safe Action system. That means they share identical controls, the same takedown and maintenance steps, comparable trigger feel, and the same core reliability and low-maintenance expectations you expect from a Glock.
