Glock 19 Gen 6: What Owners Should Know About Concealed Carry, Holster Fitment, and Kydex Protection

The Glock 19 has long been one of the most recognizable compact 9mm pistol platforms, valued for its balance of size, versatility, and practical everyday use. With the Glock 19 Gen 6, owners have another generation to consider when selecting accessories, particularly an inside-the-waistband (IWB) holster.

For anyone considering concealed carry with the Glock 19 Gen 6, selecting the correct holster is just as important as choosing the firearm itself. A properly fitted holster should provide dependable retention, full trigger-guard coverage, comfortable positioning, and reliable attachment to the belt.

At STS Concealment, we understand the importance of model-specific fitment. Our American-made Kydex holsters are designed with durability, concealment, and everyday practicality in mind.

Understanding the Glock 19 Gen 6

The Glock 19 platform occupies a popular position between full-size duty pistols and smaller concealed-carry handguns.

Its compact dimensions make it appealing to owners looking for a firearm that can serve multiple purposes, including recreational range use, training, and lawful concealed carry.

When evaluating the Glock 19 Gen 6, owners should pay particular attention to its frame geometry, trigger-guard profile, slide configuration, and accessory compatibility.

Even relatively small design changes between generations can influence how a firearm fits inside a molded holster.

This is especially important with rigid Kydex holsters, which depend on carefully formed contact points to provide appropriate retention.

Why Holster Compatibility Matters for the Glock 19 Gen 6

One of the most important considerations when purchasing a holster for a new Glock generation is compatibility.

Although different Glock 19 generations share similar overall dimensions, that does not automatically mean every holster is interchangeable.

Potential differences in frame contours, trigger-guard geometry, accessory rails, and slide configurations can affect fitment.

A holster that appears compatible may still create problems if it does not properly accommodate the firearm.

A correctly fitted holster should:

• Completely cover the trigger guard.

• Securely retain the firearm during ordinary movement.

• Allow the firearm to seat fully without excessive force.

• Avoid interfering with controls or accessories.

• Maintain its shape when the firearm is removed.

• Provide a consistent, unobstructed draw.

Important: Glock 19 Gen 6 owners should verify compatibility with their exact firearm configuration rather than assuming that a holster designed for Gen 5 or earlier models will fit.

Why Kydex Is a Popular Choice for Concealed Carry

Kydex has become a widely used material in modern holster manufacturing because of its rigidity, durability, and ability to be precision-molded.

Unlike soft materials that can collapse when empty, a properly manufactured Kydex holster maintains its shape.

This helps preserve the holster opening and supports consistent firearm positioning.

Benefits of .08-Inch Kydex Construction

Durability: Kydex resists ordinary wear and maintains its molded structure through regular use.

Secure Retention: A properly formed shell helps hold the firearm securely while allowing a predictable draw.

Slim Profile: Kydex can provide a relatively low-profile design without unnecessary material bulk.

Moisture Resistance: The material does not absorb moisture like some traditional holster materials.

Easy Maintenance: Most routine surface dirt can be removed with a soft cloth and appropriate cleaning methods.

For Glock 19 Gen 6 owners, these qualities make a properly fitted Kydex holster a practical option for everyday concealed carry.

IWB Carry: Comfort and Concealment

Inside-the-waistband carry remains a common option for concealed handgun owners.

An IWB holster positions the firearm inside the waistband, allowing clothing to cover much of the holster and firearm.

Because the Glock 19 is a compact rather than a micro-compact pistol, holster design can make a meaningful difference in concealment and comfort.

Several factors influence the experience:

Adjustable Cant

Cant refers to the angle at which the firearm sits inside the holster.

An adjustable cant allows the wearer to select a positioning angle appropriate for their carry location and personal comfort.

Adjustable Retention

Retention determines how firmly the holster holds the firearm.

An adjustable retention system allows the owner to fine-tune the resistance while ensuring the firearm remains secure.

Belt Clip Security

A dependable belt attachment helps prevent unwanted holster movement.

STS Concealment offers a FOMI-style clip designed for belts up to 1.75 inches wide on applicable holster configurations.

Optional Concealment Claw

A concealment claw can help reduce printing by encouraging the grip to sit closer to the body.

This feature may be particularly useful for certain appendix IWB carry configurations.

Comfort and concealment will vary depending on clothing, body shape, belt selection, and carry position.

Optic Compatibility: Another Important Consideration

Modern pistol owners increasingly use slide-mounted red dot optics.

However, not every holster provides adequate clearance for an optic-equipped firearm.

A holster with an appropriate optic cut may accommodate compatible red dot configurations without interference.

Before ordering, owners should confirm the exact slide and optic setup, including any aftermarket modifications.

The presence of an optic cut does not guarantee compatibility with every optic or mounting arrangement.

For the Glock 19 Gen 6, selecting a holster specifically verified for the firearm's configuration is essential.

Glock 19 Gen 6 Holster Safety Considerations

Before carrying any firearm in a new holster, proper fitment and safe handling should be confirmed.

Always begin with an unloaded firearm, following established firearm safety procedures.

Check that the firearm seats completely, the trigger guard is fully covered, and the holster does not interfere with the trigger or other controls.

Inspect the holster regularly for loose hardware, cracks, excessive wear, or changes in retention.

Never force a firearm into a holster that does not fit correctly.

Owners should also follow applicable federal, state, and local laws regarding firearm possession and concealed carry.

Final Thoughts: Choosing the Right Glock 19 Gen 6 Holster

The Glock 19 Gen 6 continues the legacy of a compact 9mm platform that attracts interest from recreational shooters and concealed-carry owners.

However, choosing a suitable holster requires more than simply matching the Glock 19 name.

Generation-specific fitment, proper trigger-guard protection, secure retention, and accessory compatibility are all important considerations.

A well-designed IWB Kydex holster can provide the structure, durability, and adjustable features many owners seek for everyday carry.
