The most useful starting points are Vedder’s adjustable LightTuck for a rail-equipped G48, Tenicor’s CERTUM LUX4 when you carry its compatible light, and Tulster’s ARC for specific listed light combinations. Verify your exact setup in the maker’s current fit selector before buying.
What to check before choosing a Glock 48 IWB holster
Start with the pistol as it is actually configured—not just the model name. Holster makers distinguish among Glock 48 versions and accessories, and a light-bearing holster may depend on the light being mounted to achieve its intended fit.
- Pistol configuration: Confirm whether your G48 has a rail or MOS configuration and account for any aftermarket changes.
- Mounted light: Match the exact light model to the holster listing. Some light-bearing shells are designed to fit only with the specified light attached.
- Optic: Look for an explicit optic-ready claim if you use a slide-mounted optic; do not assume every shell clears one.
- Carry mode: Check whether the maker describes the holster as IWB generally, AIWB/IWB, or for another carry mode.
- Adjustments: Compare stated retention, cant, and ride-height adjustments if you want to tune how the holster sits.
These checks establish whether a maker says a holster fits your setup. They do not predict comfort for every body type, clothing choice, or carry position.
Glock 48 IWB holster options by configuration
| Option | Maker-stated features | Best fit to consider | Verify before purchase |
|---|---|---|---|
| Vedder LightTuck | IWB model listed for Glock 48 with rail; adjustable retention, cant, and ride height. The page offers light and optic selectors. | A rail-equipped G48 when you want carry-position adjustments. | Use the current selector to confirm rail, optic, and mounted-light configuration. |
| Tenicor CERTUM LUX4 | AIWB/IWB light-bearing model for G43/43X/48; maker says it is optic ready and has adjustable retention and cant. The G43/43X/48 version works only with the light attached. | A G48 setup using the compatible weapon light required by this holster version. | Match the actual light model and confirm that this is the light-bearing configuration you intend to carry. |
| Tulster ARC | Product page shows light-bearing IWB configurations for Glock 48/MOS with named Streamlight TLR-7 Sub family variants. | A G48 or MOS setup already built around one of the lights listed on the product page. | Select the exact pistol and light variant; the listed evidence does not establish broader compatibility. |
These are configuration-based options, not a tested ranking. The cited product pages describe maker claims and features; they do not establish comparative comfort, durability, concealment performance, or a most-secure choice.

Where the factory GLOCK holster fits in
GLOCK lists a slim Sport/Combat polymer holster for the G43, G43X, and G48, describing a flat design that sits close to the body. The cited GLOCK page does not identify it as IWB, so treat it as a factory-compatible holster option rather than an established IWB pick. Check the intended carry mode on the current product information before relying on it for inside-the-waistband carry. GLOCK Sport/Combat holster.
Why the G48’s exact configuration matters
GLOCK’s January 2, 2018 launch announcement described the G48 as having a 6.85-inch slide and the G43X as having a 6.06-inch slide; it also said the models share a frame size but have different slide lengths. Those are manufacturer-reported launch specifications, not a complete description of every current-market variant. GLOCK’s 2018 Slimline announcement.

How to confirm fit and use the holster as intended
- Identify your exact pistol: Record whether it is a standard, rail-equipped, or MOS G48, plus any slide, optic, or frame changes.
- Open the manufacturer’s current fit listing: Select the exact model and accessory configuration rather than relying on a generic “Glock 48” label.
- Match any light requirement: For a light-bearing shell, confirm the listed light and whether it must remain mounted. Tenicor explicitly requires the light on its G43/43X/48 CERTUM LUX4 version.
- Check optic and adjustment claims: Confirm that optic clearance is stated if needed, then review the available retention, cant, and ride-height adjustments.
- Follow official instructions: Use the holster maker’s fit and use directions and consult GLOCK’s owner resources for firearm handling and maintenance information. GLOCK owner resources.
