Description
The Ruger LC9 and LC380 earned their keep by being thin and easy to hide, so it makes sense to pair them with a holster that follows the same playbook. The DeSantis Slim-Tuk is a stripped-down inside-the-waistband rig molded from Kydex to fit the LC9, LC380, and EC9s, and it keeps the footprint about as small as an IWB holster gets. No extra padding, no bulky backing, just a hard shell that protects the trigger guard and holds your pistol at a consistent angle every time you put it on.
What Makes the Slim-Tuk Different
The standout feature here is the tuckable 360 C-Clip. Instead of locking you into one carry position, the clip rotates to give you essentially unlimited adjustment for cant and ride height. Run it strong side with a slight forward tilt, drop it in at appendix, or shift it back toward the hip. And since the hardware reverses, one holster covers both right and left handed carry, which is handy if you shoot with either hand or share gear in the household. The tuckable design also means you can pull a shirt down over the pistol with only the clip showing along your belt line.
Built for Everyday Carry
At roughly three ounces, you will barely notice the Slim-Tuk is there until you need it. The precision-molded Kydex gives the pistol a satisfying click when it seats, and an adjustable tension device lets you dial retention to your liking, snug for active days or a bit lighter for a faster draw. The rugged 1.75 inch nylon clip grabs most everyday carry belts securely and holds up to repeated on-and-off use without loosening its grip.
A Smart Match for Your Ruger LC9 or LC380
DeSantis has been making carry gear since 1972, and the Slim-Tuk reflects that experience: simple, durable, and adjustable where it counts. If your LC9 or LC380 has been riding in a floppy nylon pouch or a pocket, this is a meaningful upgrade that keeps the trigger covered, the draw consistent, and the whole package easy to conceal day after day.

Frequently Asked Questions
Will the DeSantis Slim-Tuk fit the Ruger EC9s or LC9s?
Yes on the EC9s. DeSantis lists this model for the Ruger LC9, LC380, and EC9s, since those pistols share the same frame dimensions. The striker-fired LC9s is nearly identical in size as well, so it typically fits, but the holster is officially molded for the LC9, LC380, and EC9s.
Can I switch the Slim-Tuk from right-hand to left-hand carry?
You can. The holster is fully ambidextrous, and the mounting hardware reverses with basic hand tools in a few minutes. That makes it a solid pick for lefties, who often get overlooked, or for anyone who trains with both hands.
How adjustable is the carry position on this holster?
Very. The tuckable 360 C-Clip rotates to let you set nearly any cant angle and ride height, so you can run it strong side, appendix, or behind the hip. There is also a tension screw so you can fine-tune how firmly the Kydex grips your pistol.
Can I tuck a shirt in over the DeSantis Slim-Tuk?
Yes, that is the point of the tuckable clip design. The C-Clip stands off from the holster body so you can tuck a shirt between the holster and your waistband, leaving only the low-profile clip visible on your belt. It is a practical setup for anyone who carries in business casual or dressier clothing.
