Concealed Carry Holster For Glock 23: Vedder

Why you should trust this guide

I have spent years researching concealed carry holsters, reading owner feedback across forums, and studying how different designs affect comfort, retention, and draw speed. For this guide, I focused specifically on the Glock 23, a compact .40 caliber pistol that demands a holster with precise trigger guard coverage and reliable retention. I evaluated each product based on the manufacturer’s stated features, build materials, and real-world reports from carriers who use these holsters daily. My goal is to give you a clear, honest comparison so you can choose the right holster for your carry style without guessing.

Every holster listed here is currently available and widely used. I did not test these products in a lab or run controlled drills. Instead, I weighed what matters most for concealed carry: retention adjustability, comfort during extended wear, concealment profile, and build quality. I also looked at each holster’s ability to fit the Glock 23 specifically, not just a generic Glock 19 shell. The recommendations below reflect a balance of proven design, owner satisfaction, and practical features for everyday carry.

How we researched

To evaluate these holsters, I established a set of criteria that matter for a compact .40 caliber pistol like the Glock 23. The first factor was retention and safety: how well does the holster cover the trigger guard, and can the user adjust the draw weight to prevent accidental release? The second factor was concealment: does the holster keep the pistol close to the body, and does it allow for cant or ride height adjustments to hide under a shirt or jacket? The third factor was comfort during extended wear: does the holster use materials that reduce pressure points, and is the clip design secure without digging into the hip? I also considered modularity for carriers who want to switch between carry positions.

For each product, I reviewed the manufacturer’s specifications, including material thickness, clip type, and retention mechanism. I cross-referenced these details with owner feedback from multiple online communities to identify common strengths and limitations. I did not physically handle or wear these holsters. Instead, I relied on the stated features and reported experiences to determine which holsters meet the needs of a Glock 23 carrier. The final picks reflect those that offer the best combination of adjustability, security, and concealment for their respective categories.

Vedder LightTuck IWB, Best Overall Holster for Glock 23

The Vedder LightTuck is a full Kydex holster molded specifically for the Glock 23. It uses a single metal belt clip that keeps the holster secure while allowing for easy on and off. The shell wraps tightly around the trigger guard with no exposed gap, which is critical for safe carry with a compact .40. The retention screw lets you tune the draw weight to your preference, so you can set it as tight or loose as you like. The sweat shield extends high enough to keep the slide off your body, which also adds stability during all-day wear. Vedder machines each shell to order, which means the fit is specific to your Glock 23 and not a generic mold.

The holster offers fully adjustable retention, cant, and ride height. You can change the cant from straight drop to a forward tilt, and the ride height can be set to deep concealment or a more accessible position. The low-profile spring steel clip is rated for belts up to 1.75 inches and holds firmly during movement. The rigid Kydex construction supports smooth reholstering without collapsing, which is important for practice and administrative handling. One honest limitation is that the single clip design can allow the holster to shift slightly on very active days, especially if you carry in a position other than strong-side hip. Some users also note that the sweat shield can dig into the abdomen if you carry appendix, though this is less common with the Glock 23’s shorter grip.

Overall, the Vedder LightTuck delivers a precise, adjustable, and secure carry solution for the Glock 23. It is not the cheapest option, but the custom fit and build quality justify the investment for most carriers.

Alien Gear ShapeShift 4.0 IWB, Best Modular System for Glock 23

The Alien Gear ShapeShift 4.0 uses a modular shell-and-base system. The Glock 23-specific Kydex shell attaches to different bases, allowing you to switch between IWB, OWB, and appendix carry without buying separate holsters. This makes it a strong choice for carriers who want flexibility. The IWB base uses a neoprene backer that softens pressure points, which helps during extended carry sessions. Retention is adjustable via a screw, and the shell locks into each base with a positive click. The system also includes options for a sidecar attachment and double stack magazine carrier, expanding its utility.

The holster is designed for ambidextrous carry and fits Glock 43X MOS and 48 MOS models, but the shell for the Glock 23 is specific to that pistol. The neoprene backer breathes better than solid Kydex against the skin, reducing sweat buildup. One honest limitation is that the modular design adds bulk compared to a dedicated IWB holster. The base and backer can feel thick on the belt, which may affect concealment for some body types. Additionally, switching between carry configurations requires carrying the extra bases, which is not ideal if you only need one carry style. The retention is reliable, but the system’s complexity can be overkill for carriers who simply want a simple IWB holster.

For those who want one holster that can adapt to different carry positions and clothing choices, the Alien Gear ShapeShift 4.0 offers unmatched versatility. It is not the most minimalist option, but the modularity is a genuine advantage for carriers who experiment with carry styles.

Safariland 6378 ALS, Best OWB Holster for Glock 23

The Safariland 6378 ALS uses the Automatic Locking System for passive Level II retention. When you holster the Glock 23, the ALS mechanism locks onto the ejection port, securing the pistol. To draw, you press a thumb-actuated lever and pull straight up. This provides a high level of security against accidental dislodging while allowing a natural draw stroke. The holster attaches via a paddle for fast on and off without re-threading your belt, and it also includes a belt loop attachment for more secure carry. The paddle is contoured for hip carry and features a slight forward cant for better concealment under a cover garment.

The holster body is made from genuine SafariLaminate thermoformed construction with a suede lining that helps protect the gun’s finish. The belt loop adjusts for cant and fits belts from 1.5 to 1.75 inches wide. The holster rides close to the body for an OWB design, which reduces printing compared to traditional duty holsters. One honest limitation is that the ALS system adds some width to the holster, making it less suitable for deep concealment under a tight shirt. The paddle attachment can also shift slightly during vigorous movement, though the belt loop attachment solves this. Additionally, the thumb-actuated release requires practice to ensure a smooth draw under stress, though it becomes natural with repetition.

The Safariland 6378 ALS is a top choice for open carry or concealed carry under a jacket. Its retention system is proven in law enforcement, and the build quality is excellent. For Glock 23 owners who prioritize security and quick access, this holster is a solid investment.

Tulster Profile IWB, Best for Appendix Carry with Glock 23

The Tulster Profile holster is designed with a minimal footprint and precise shell forming for the Glock 23. It includes an integrated AIWB wing attachment that pushes the grip toward the body at the appendix position, which significantly reduces printing through lighter cover garments. The clip is rated for belts up to 1.75 inches and stays planted during movement. Trigger guard coverage is complete, and you get an audible click when holstering, confirming the pistol is fully seated. The cant is easily adjustable from 0 to 30 degrees, so you can fine-tune the angle for appendix or strong-side carry.

The holster is compatible with Glock 19, 19X, 23, 25, 32, 44, and 45 pistols, but each shell is formed specifically for the Glock 23 frame. The retention is adjustable via a screw, allowing you to set the draw weight to your preference. The holster is made from .08 inch thick Kydex and is proudly manufactured in the USA. One honest limitation is that the wing attachment can create a pressure point against the thigh during appendix carry, especially if you have a shorter torso. Some users also report that the single clip allows the holster to rotate slightly if you carry at the 3 o’clock position, though this is less of an issue for appendix carry. The sweat shield is minimal, which helps with comfort but offers less protection from the slide against the skin.

The Tulster Profile is an excellent choice for appendix carriers who want a dedicated, low-profile holster. The wing attachment makes a real difference in concealment, and the adjustable cant adds versatility. It is not ideal for deep concealment in other positions, but for appendix carry, it performs well.

Rounded Gear Kydex IWB, Best Budget Holster for Glock 23

The Rounded Gear Kydex IWB holster is a serviceable full Kydex option at an accessible price point. The shell is molded to the Glock 23 frame with adequate trigger guard coverage and adjustable retention. Cant adjustment is available via the single metal clip, allowing you to tilt the holster forward for better concealment. The shell is slightly thinner than premium alternatives, which can introduce minor flex when reholstering, but passive retention is still secure during daily carry. The holster is claw compatible, meaning you can add a claw attachment to further reduce printing.

The holster fits Glock 23 Gen 5-6 models specifically. It features adjustable Posi-Click retention, which gives an audible click when the pistol is fully seated. The cant is also adjustable, so you can customize the carry angle. The holster is 100% made in the USA. One honest limitation is that the thinner Kydex can flex more than thicker shells, which may cause the holster to lose its shape over time if you frequently reholster without looking. The single clip can also allow the holster to shift on the belt during active movement, though this is common in budget designs. The sweat shield is minimal, so the slide can contact the skin more directly than with higher-end holsters.

For carriers on a budget who still want a functional Kydex holster, the Rounded Gear is a solid choice. It provides the essential features of retention and cant adjustment without the premium price. It is not the most durable or comfortable option, but it gets the job done for everyday carry.

What to look for

• Trigger guard coverage: The holster must fully cover the trigger guard to prevent accidental discharge. Look for a shell that wraps tightly with no exposed gaps.
• Retention adjustability: A retention screw allows you to set the draw weight to your preference. This is important for both security and ease of draw.
• Cant and ride height adjustment: The ability to tilt the holster forward or change how high it sits on the belt helps with concealment and comfort for different body types.
• Clip or attachment system: A sturdy metal clip rated for your belt width keeps the holster secure. Single clips are common but can shift; dual clips offer more stability.
• Material and construction: Kydex holsters offer rigid retention and consistent performance. Thicker Kydex (.08 inch or more) resists flexing during reholstering.
• Concealment features: Wings or claws that push the grip toward the body reduce printing, especially for appendix carry. A sweat shield protects the slide from skin contact.
• Modularity: If you want to switch between IWB, OWB, or appendix carry, a modular system like the Alien Gear ShapeShift can save money and space.

The verdict

For most Glock 23 carriers, the Vedder LightTuck IWB is the best all-around choice. It offers precise custom fit, full Kydex coverage, and three-way adjustability for retention, cant, and ride height. If you need modularity to switch between carry positions, the Alien Gear ShapeShift 4.0 is a versatile alternative. For open carry or carry under a jacket, the Safariland 6378 ALS provides excellent retention with its Automatic Locking System. Appendix carriers should consider the Tulster Profile for its integrated wing that reduces printing. And if budget is your primary concern, the Rounded Gear Kydex IWB delivers essential features at a lower cost. Choose based on your carry style and priorities, and you will find a holster that fits your Glock 23 securely and comfortably.
