For a Glock 48 IWB holster, start by confirming exact firearm fit—not by assuming one material is universally best. Kydex or polymer shells are rigid and shaped; hybrid holsters pair a rigid shell with a softer leather backer. The available sources do not establish a universal winner for comfort, concealment, draw speed, durability, or reholstering.
How the materials differ
Kydex or polymer: a rigid, shaped shell
A rigid shell is formed for a particular firearm. Comp-Tac describes the Kydex body of its MTAC as a rigid material custom fit to each firearm, while GLOCK describes its slim polymer accessory as flat and designed to sit close to the body. Those are manufacturers’ descriptions of construction and design intent, not independent findings about comfort, concealment, speed, or safety.

GLOCK’s Sport/Combat holster listing identifies compatibility with the G43, G43X, and G48. Do not infer that every polymer holster fits every G48 configuration.

Leather: not established here as a standalone option
In the documented G48 examples, leather appears as the backing in hybrid designs. The available sources do not confirm a standalone all-leather G48 IWB model, or establish comparative evidence about leather break-in, maintenance, durability, or performance when wet.

Hybrid: rigid shell plus a softer backer
Hybrid designs combine a formed shell with a backer. Comp-Tac describes its MTAC as a Kydex-and-leather IWB holster with top-grain cowhide backing, and says the backing does not rub or pinch; that comfort statement is the company’s claim, not a comparative test.
Other maker-described examples include Black Arch’s Gradient Hybrid IWB, listed for G48 and G48 MOS with configuration-specific options, and Vedder’s RapidTuck, described as premium leather plus molded Kydex for the Glock 48.

What the evidence can—and cannot—tell you
There is no controlled, independent head-to-head comparison here of Kydex, leather, and hybrid holsters. A first-person editorial passage in GLOCK Annual 2023 states a preference for Kydex, citing less excess material, an open mouth, and a slicker draw feel. The passage does not identify its author and is not a tested comparison. It should be read as one published preference, not a general result.
Material alone does not establish how a particular holster will feel or perform for a particular person. Compare construction and fit, then consider the maker’s stated features as claims rather than proof of an overall advantage.

Check fit before choosing a G48 IWB holster
- Match the exact pistol and configuration. Confirm the manufacturer explicitly lists the Glock 48 and, where relevant, G48 MOS. Check whether fit differs for a rail, optic, or weapon-mounted light. Black Arch’s listing, for example, specifies G48/G48 MOS and describes railed/non-railed and light-specific options; those details apply to that product, not all hybrids.
- Confirm handedness and carry position. Check the current product listing for left- or right-hand orientation and intended position. Comp-Tac lists multiple model and orientation options and describes the MTAC as worn behind the hip at 4 or 5 o’clock.
- Compare attachment and retention details. Verify the attachment system and any retention adjustment on the exact variant’s current listing. Do not assume options carry over between models or configurations.
- Follow the maker’s instructions and firearm safety guidance. The sources do not establish a product-independent safety certification or a comparative safety test for these material categories.
