Description
The Glock 48 changed a lot of minds about what a carry gun should be, and this Gen5 MOS version is the one most people end up wanting. It keeps the same footprint as the legendary G19 in length and height, but trims the width down to just 1.10 inches. That slim profile is what makes it so easy to carry all day, whether you run it inside the waistband or in a bag. The 4.17 inch match-grade Glock Marksman Barrel gives you a longer sight radius and better velocity than the micro nines, so it shoots more like a full-size gun than its slim build would suggest.
Optic Ready and Rail Equipped
This is the MOS version with the front rail, which means you get the best of both worlds. The slide is cut for popular micro red dots that mount directly without adapter plates, so pairing it with a compact optic is quick and clean. Up front, the Glock Slim Mounting Rail accepts weapon lights and lasers built for slimline pistols. Add in the precision-milled front serrations for easier press checks and you have a carry pistol set up for how people run guns today.
Gen5 Details That Matter on the G48
Glock brought its best updates to this platform. The frame has a built-in beavertail for a high, comfortable grip, the mag catch is reversible for left-handed use, and the nDLC finish on the slide shrugs off sweat and holster wear. The Safe Action trigger system delivers the same consistent pull from the first round to the last, with three independent internal safeties working automatically in the background.
What Comes with the Glock 48 Gen5 MOS
You get two slim 10-round magazines with high-visibility orange followers, so one stays loaded while the other rides as a spare. At just over 18 ounces unloaded, this pistol carries light and shoots soft for its size. If you want a slim nine that does not force you to give up barrel length, sight radius, or a real grip, the G48 MOS is hard to argue with.

Frequently Asked Questions
What red dots fit the Glock 48 Gen5 MOS slide?
The G48 MOS slide is cut for micro optics that use the RMSc-style footprint, so popular compact dots like the Holosun 507K, Shield RMSc, and similar slim optics mount directly to the slide. Keep in mind the G48 MOS does not ship with adapter plates, so choose an optic that matches the footprint or grab the appropriate mounting hardware for it.
Does the Glock 48 MOS have an accessory rail for a light?
Yes, this version includes the Glock Slim Mounting Rail on the frame. It accepts weapon lights and lasers designed for slimline pistols, like the Streamlight TLR-7 Sub and similar compact lights. Just make sure the light you pick is made for the G48/G43X rail rather than a standard Picatinny-only model.
How does the Glock 48 compare to the Glock 19 for concealed carry?
The G48 is nearly identical to the G19 in length and height, but it is noticeably thinner at just 1.10 inches wide, which makes it print less and ride more comfortably inside the waistband. The trade-off is capacity, with the G48 holding 10 rounds in its slim magazine versus 15 in the G19. Many people find the flatter profile worth it for all-day carry.
Will Glock 43X magazines work in the Glock 48 Gen5 MOS?
Yes, the G48 and G43X share the same slim frame and use the same 10-round magazines, so mags swap freely between the two. This pistol ships with two factory 10-rounders featuring orange followers for quick visual confirmation of an empty mag.
