Video: How The Glock 43X And Glock 48 Advance The Slimline Series


Glock's extremely popular Slimline Series took a big step forward with the enhanced-capacity Glock 43X and Glock 48.

Undoubtedly, Glock has been among the top players in the concealed carry pistol market. Outside of their long-slides, there’s a case to be made that nearly every model in the legendary gunmaker’s catalog is a potential undercover option, at least for some armed citizen out there. In recent years, however, the company has turned its studied eye to producing pistols optimized to the hilt for everyday carry.

The Glock Slimline Series is the gunmaker’s response to consumer demand for single-stack options. This year the line got a couple upgrades that make it hard to deny Glock is hitting its groove with this configuration. The Glock 43X and Glock 48 not only offer enhanced capacity over the original Slimline G42 and G43, but greater shootablity. Actually the two walk hand-in-hand for the 9mms.

To squeeze in more rounds for 10+1 capacity, Glock had to extend the grip of the pistols. Given its mastery at packing rounds into limited real estate, the lengthening wasn’t by leaps and bounds. With a magazine, the Glock 43X and Glock 48 both have a height of 5.04 inches, which is around ¾ of an inch greater than the Glock 43. This shouldn’t make them a bear to conceal, at the same tick, most shooters will have enough grip to get their entire hand on the pistols. It makes a difference.

Not satisfied with simple capacity and shootablity upgrades, Glock also decked out the Slimline Series additions with a few other notable features. The most prominent are the fore and aft cocking serrations and a rather striking silver-finished slide. Definitely a different look for a factory Glock. Also, the G48 is a bit of a break as well. While the G43X, predictably, mirrors the G43, the G48 is built along the Glock 19’s dimensions. If you carry the tried and true double-stack, the Glock 48 might prove the perfect warm-weather complement.
