The 48 is a gun Glock should have built a decade ago. It’s an awesome little gun. Dimensionally, it is absolutely as small as you can go under our regulations; slightly smaller in every direction, other than the barrel, than a 19. The barrel is actually slightly longer than a 19, without extending beyond the slide as much. The grip is perfect for smaller hands, and it’s an accurate shooter. I’m enjoying this gun more than any other Glock I’ve owned...by a lot.
