Description
The Sig P938 earned its reputation as a single-stack 9mm you can carry all day without thinking about it, and the DeSantis Slim-Tuk is built to keep it that way. This is a minimalist inside-the-waistband holster formed from Kydex sheet and molded specifically to the P938, so the fit is snug and the trigger guard stays fully covered. There is no bulk, no extra material, just enough holster to do the job right. It also fits the Kimber Micro 9 if you happen to run both.
What Makes the Slim-Tuk Different
The standout feature here is the tuck-able 360 C-Clip. Most budget Kydex holsters lock you into one ride height and one cant angle. The Slim-Tuk's clip rotates a full circle, so you can set it up for strong side, appendix, cross draw, or just about any angle in between. Because it is tuckable, you can pull a dress shirt down over the pistol and clip and still get to your gun when it counts. The rugged 1.75 inch nylon clip grabs your belt and stays put, and the hardware reverses in a few minutes with basic tools if you shoot left handed or want to switch sides.
Retention You Can Dial In
Retention comes from the molded Kydex itself plus an adjustable tension device, so you can tighten things up for a crisp, positive snap when the pistol seats, or back it off for a smoother draw. Kydex also shrugs off sweat and weather in a way leather never will, which matters for a rig that rides against your body all summer.
Living With the Slim-Tuk and Your P938
At only a few ounces, this holster adds almost nothing to an already lightweight pistol. The open bottom design keeps things simple and lets debris fall through instead of collecting in the holster. Keep in mind this one is cut for a standard P938, so pistols wearing a rail-mounted laser will not fit. For a clean, affordable way to carry a P938 every day, the Slim-Tuk is hard to argue with.

Frequently Asked Questions
Can I set up the Slim-Tuk for left-handed carry?
Yes. The Slim-Tuk ships as an ambidextrous holster, and the clip hardware can be reversed to switch from right to left hand carry. All it takes is a screwdriver and a couple of minutes. That also makes it easy to experiment with different carry positions.
Will the Slim-Tuk fit a Sig P938 with a laser attached?
No. This holster is molded to the standard P938 frame and will not accommodate a rail-mounted laser or light. If your pistol wears a laser, you will want a holster molded specifically for that setup. A bare P938 or one with standard sights fits great.
Does this holster fit anything besides the P938?
It does. This same mold fits the Kimber Micro 9, since the two pistols share very similar dimensions. If you rotate between those two guns, one Slim-Tuk covers both.
How adjustable is the retention on the DeSantis Slim-Tuk?
Retention comes from the molded Kydex plus a tension screw you can adjust to taste. Tighten it for a firm click when the pistol seats, or loosen it for a faster, smoother draw. Most folks find a good middle ground in a few minutes of tinkering.
