Glock 48 Overview
The Glock 48 is a Slimline 9mm with a 4.17-inch barrel. GLOCK says it is of similar length and height as the G19, but with a reduced width for better carrying comfort.
Current models include the GLOCK Slim Mounting Rail, and the G48 MOS version is cut for micro red dots.
Glock 43X Overview
The Glock 43X uses the same compact-size grip as the G48, according to GLOCK, but pairs it with a shorter slide and a 3.41-inch barrel.
It also has the Slim Mounting Rail on current models, and a G43X MOS version is available for optics.
Size and Concealability
The only real size difference is the slide. Based on GLOCK’s published specs, both pistols are 5.04 inches tall and 1.10 inches wide, but the G48 is about 0.78 inch longer and about two ounces heavier.
The grip is usually the part that prints, and here the grips are the same. That is why many buyers find the 48 conceals almost as easily as the 43X.
Capacity and Magazines
GLOCK’s product pages list a 10-round slim magazine for both pistols. In April 2026, GLOCK announced that G43X and G48 pistols will ship standard with new 15-round, metal, double-stack Slimline magazines starting in May 2026.
Because both versions are still on the market, check the listing for the exact magazine your pistol ships with. The good news is that the 43X and 48 share magazines, so one set of mags works in both.

Range Use and Shootability
The G48’s longer barrel and slide give you a longer sight radius than the 43X. Many shooters find that makes the 48 a little easier to shoot accurately at the range.
The 43X’s shorter slide can be easier to draw and sit with, especially when carrying inside the waistband in front of the hip.
