Glock 48
The Glock 48 is a slim 9mm pistol that combines the single-stack width of the Glock 43X with a longer 4.17-inch barrel and full-length slide. It holds 10+1 rounds and has a longer sight radius than the shorter G43X. Impact Guns carries the standard Glock 48 and the Glock 48 MOS, which adds a factory optics cut for mounting a micro red dot. It suits concealed carry buyers who want a little more barrel.

Glock 48 vs. Glock 43X: Same Width, More Barrel
The Glock 48 and Glock 43X share the same frame, grip and magazines. The difference is the slide and barrel: 4.17 inches on the G48 and 3.41 inches on the G43X. A longer barrel gives a longer sight radius, which many shooters find easier to shoot accurately. Muzzle velocity also rises a little with a longer barrel. Choose the G43X when the shortest overall length matters most.
Glock 48 MOS: The Optics-Ready Version
The Glock 48 MOS has a factory-milled slide that accepts Glock MOS adapter plates for several micro red dots. That lets you add a sight now or later without milling the slide. Check your optic's footprint against the plate list first. For carry optics, compare the Holosun 507K and the Holosun EPS Carry.
Shield Arms S15 Magazines for the Glock 48
The Glock 48 uses 10-round magazines. Shield Arms makes the S15, an aftermarket 15-round magazine for the G43X and G48 that keeps a flush fit. Shield Arms says the S15 needs its metal magazine catch to function as designed. With S15 magazines, the G48 reaches Glock 19 capacity in a slimmer grip. Check your state's magazine laws before buying higher-capacity magazines.
Carrying the Glock 48
The G48 has the same slim grip as the G43X, so most inside-the-waistband holsters made for the longer slide work well. The slide is longer than the G43X's, so check holster fit for the G48 specifically. Appendix and strong-side carry are both common. A slim grip helps the pistol stay close to the body, but fit and comfort vary by build and clothing.
Who Should Choose the Glock 48?
Choose the G48 if you want a longer sight radius, plan to run a red dot, or want to use S15 magazines. Choose the G43X if you need the shortest possible Glock or mostly carry in a pocket. Choose the Glock 19 if you want more standard capacity and can accept a thicker grip.
