Description
The Glock 48 was built to be thin and easy to hide, so it never made sense to stuff it into a bulky holster. The DeSantis Slim-Tuk keeps things simple: a precision-molded Kydex shell, a single sturdy clip, and adjustable retention. That's the whole recipe, and it works. The molding gives the G48 an audible click when it seats, and the tension screw lets you dial retention anywhere from range-day snug to a quick, smooth draw for everyday carry. It also fits the 48 MOS, with or without a red dot mounted.
Carry the Slim-Tuk Your Way
The standout feature here is the tuckable 360 C-Clip. It rotates to nearly any angle, so you can run this at strong side with a forward cant, appendix with a neutral drop, or anywhere in between. Ride height adjusts too, letting you tuck the pistol deeper for maximum concealment or ride it higher for a faster grip. And since the hardware is fully reversible, lefties get the exact same holster as righties without paying extra or waiting on a special order. The clip fits belts up to 1.75 inches wide and hangs on tight, so the holster stays put on the draw instead of coming out with the gun.
Slim-Tuk Kydex That Handles Real Life
Kydex earns its keep in a holster like this. It won't collapse when the gun comes out, so one-handed reholstering is easy, and it shrugs off sweat and summer humidity in a way leather never will. At well under half a pound, you'll forget it's there until you need it. The tuckable design means you can wear a shirt over the clip and keep things low profile even in business casual.
For Glock 48 owners who want a proven IWB setup without a pile of straps and paddles to fuss with, the Slim-Tuk is a hard combination of simplicity and adjustability to beat. Clip it in, set your angle and tension once, and get on with your day.

Frequently Asked Questions
Will the Slim-Tuk fit a Glock 48 MOS with a red dot mounted?
Yes. This version of the Slim-Tuk is cut for the Glock 48 and 48 MOS, with or without an optic on the slide. Keep in mind it is molded for the standard pistol, so a weapon light or laser on the frame will not fit.
How do I switch the Slim-Tuk from right-hand to left-hand carry?
The hardware is fully reversible. Just remove the screws, flip the C-Clip to the opposite side of the shell, and reattach. It takes a few minutes with a basic screwdriver and no extra parts are needed.
Can I adjust the cant and ride height on this holster?
Yes, that's one of its best tricks. The 360 C-Clip rotates to nearly any angle, so you can set a forward cant for strong-side carry, run it straight up for appendix, or tuck it deeper for more concealment. There is also a tension screw to fine-tune how firmly the holster grips the pistol.
Does the Slim-Tuk work with a tucked-in shirt?
It does. The C-Clip is a tuckable design, meaning you can tuck your shirt between the holster body and the clip so only the small clip shows on your belt. That makes it a solid pick for office wear or anywhere you need deeper concealment.
