Best IWB Holster for Glock 26, 27, and 33 (Gen 3–4) – Comfort Meets Concealment

Posted by STS Concealment on Apr 26th 2026

When it comes to concealed carry, few platforms are as trusted as the Glock 26, Glock 27, and Glock 33. Known for their compact size, reliability, and versatility, these double-stack pistols have become a go-to choice for everyday carry. But pairing them with the right holster is what truly unlocks their potential.

That’s where the STS Concealment IWB Kydex Holster comes in.

Why the Glock 26 / 27 / 33 Are Ideal for Concealed Carry

The Glock 26 (9mm), Glock 27 (.40 S&W), and Glock 33 (.357 SIG) all share a similar compact frame, offering a balance of firepower and concealability. Their shorter barrel length makes them easier to conceal, while still maintaining enough grip for control and capacity.

However, because they are double-stack pistols, they can print more easily without the right holster setup.

Designed for True Concealment

The STS Concealment IWB holster is precision-molded specifically for the Glock 26/27/33 platform. Built from durable .08” Kydex, it offers a slim, low-profile design that keeps your firearm close to the body for maximum concealment.

The optional concealment claw plays a major role here — rotating the grip inward to reduce printing, especially when carrying appendix.

All-Day Comfort and Adjustability

Comfort matters just as much as concealment. This holster features:

  • Adjustable retention for your preferred draw feel
  • Adjustable cant for appendix or strong-side carry
  • A durable FOMI clip that fits belts up to 1.75”

This allows you to fine-tune your carry setup based on your body type, clothing, and daily routine.

Built for Everyday Performance

Whether you're heading to work, running errands, or spending time at the range, your holster needs to perform. The STS Concealment holster delivers:

  • Consistent retention
  • Smooth, repeatable draw
  • Rugged durability for daily use

Each holster is proudly made in the USA using high-quality materials — no shortcuts, no compromises.

Final Thoughts

If you carry a Glock 26, 27, or 33, choosing the right holster makes all the difference. With its precision fit, adjustable features, and low-profile design, the STS Concealment IWB Kydex Holster is built to meet the demands of real-world concealed carry.

Carry confidently. Carry comfortably. Carry STS Concealment.
