Description
The BlackHawk TecGrip Size 01 IWB holster ditches the clip altogether. Using proprietary TecGrip fabric on the exterior, this holster clings securely to your waistband and clothing without needing any hardware to hold it in place. You loosen your pants, position the holster, tighten up, and it stays exactly where you put it—no shifting around during your day regardless of how you move.
Build and Materials
BlackHawk went with a thermal-bonded three-layer laminate construction that balances durability with a low-profile fit. The outer TecGrip fabric grips most any material you wear, while the inner layer uses high-density closed-cell foam that molds to your body for all-day comfort. The whole thing is hand or machine washable, making maintenance quick and easy.
What Makes Size 01 Different
Size 01 fits medium automatic pistols with 3 to 4-inch barrels, which covers a wide range of carry guns like the Sig P365, Glock 42, Colt Mustang, Walther PPK, and similar frames. The compact sizing keeps bulk down, which is why this holster excels at concealment compared to heavier leather or rigid polymer alternatives.
Practical Carry
Because there's no clip, reholstering takes a bit more attention than a clipped holster—you'll want to loosen your waistband slightly and use your free hand to guide the holster opening as you re-seat your firearm. The draw itself is smooth and unrestricted. The ambidextrous design works for both right and left-handed carriers without any modifications needed. At under an inch thick, this holster minimizes the bulk that betrays a concealed carry setup.

Frequently Asked Questions
How does a TecGrip holster stay in place without a clip or belt loop?
The exterior uses BlackHawk's proprietary TecGrip fabric, which has a tacky, slightly adhesive surface that grips any cloth material your pants are made from. Once you settle the holster in place against your waistband and tighten your belt, the friction and tension hold it securely without any metal hardware.
Is reholstering this holster different from a clipped holster?
Yes. You'll want to partially loosen your waistband and use your free hand to keep the holster opening accessible while you guide your firearm back in. The holster can compress under normal waistband pressure, so a little extra care during reinsertion prevents unnecessary friction. Once your gun is seated and your belt is tight again, the holster won't move.
What makes Size 01 different from the other sizes?
Size 01 is designed for medium-frame pistols with 3 to 4-inch barrels. It's the sweet spot for guns like the Glock 42, Sig P365, Colt Mustang, and Walther PPK. Larger barrels need bigger sizes, while compact and subcompact pistols typically require smaller sizes. Check your firearm's barrel length and frame size against the size chart before ordering.
Can I wash this holster?
Yes. The entire holster is hand or machine washable with soap and water. Just let it air dry completely before using it again. Regular cleaning keeps the TecGrip fabric and padding fresh, especially if you carry in warm or humid conditions.
