Glock 19X Holsters - Engineered for the Crossover Grip-to-Slide Configuration
The Glock 19X is a Gen5 crossover pistol that pairs a compact Glock 19-length slide (4.02" barrel) with a full-size Glock 17-length grip, creating a distinctive hybrid geometry.
This configuration—7.44" overall length with extended front strap, 24.09 oz unloaded weight, 17+1 capacity—delivers full-size control and shootability with compact-slide handling characteristics. The 19X's unique dimensions demand holsters engineered specifically to its profile, as standard Glock 19 holsters will not accommodate the longer grip, while Glock 17 holsters leave excess muzzle space that can compromise retention or allow unwanted movement.
Glock 19X Holster Compatibility Overview
This collection supports the Glock 19X in its standard configuration and does not include variant-specific models (MOS, light-bearing, or laser configurations are not listed in available inventory).
Each holster is precision-molded to the 19X's exact specifications, accounting for the full-size grip length, Gen5 ambidextrous slide stop, flared magwell, and front strap geometry that differentiate it from both the G19 and G17.
Critical fit requirement:
The Glock 19X uses a hybrid frame/slide combination that creates compatibility challenges. Holsters molded only for the Glock 19 will not fully accommodate the extended grip and may create pressure points or incomplete coverage.
Similarly, Glock 17 holsters designed around the longer slide leave the 19X's shorter slide partially exposed or allow excess movement within the holster shell. Only holsters explicitly stating "19X compatibility" or molded specifically for the 19X geometry will provide proper fit, retention, and trigger guard coverage.
Gen5 features include ambidextrous slide stop levers, reversible magazine catch, nDLC finish, flared magwell, and front slide serrations. The ambidextrous slide stop is a common interference point with older holsters molded tight to single-sided controls, potentially causing rub marks or binding on the right-side lever.
How to Choose the Right Alien Gear Holster for Glock 19X
Selection depends on carry method, concealment priorities, and whether you primarily use the 19X for duty applications, concealed carry, or mixed roles.
IWB Holsters serve inside-the-waistband concealed carry. The 19X's full-size grip creates concealment challenges compared to shorter-grip compact pistols—the extended grip length increases printing, particularly when bending, twisting, or sitting. Strong-side IWB carry at 3:30–4:30 typically provides the most forgiving concealment, as the hip and body contour help tuck the longer grip against the torso. Adjustable cant and ride height are essential for managing grip printing across different body types and clothing choices.
Appendix Holsters position the Glock 19X at the front of the waistline between 12 o'clock and 2 o'clock. The shorter slide clears the holster quickly and works well for seated access, but the full-size grip tends to lever outward, creating increased printing under fitted clothing. Users typically require careful ride height adjustment, wedges, or specialized cant tuning to control the grip's tendency to "tip" away from the body. This carry method demands more attention to setup and clothing choices with the 19X than with shorter-grip models.
OWB Holsters provide outside-the-waistband carry for open carry, range training, or situations where deep concealment is not required. The 19X's 24+ oz loaded weight is well-suited to OWB carry without excessive belt sag. OWB configurations offer fast access and comfortable extended wear, though concealment becomes very clothing-dependent and difficult to maintain with light cover garments.
Paddle Holsters offer tool-free attachment through paddle-style mounting that distributes weight without threading through belt loops. This allows quick on/off cycles for range sessions or situations requiring frequent holster removal.
Drop Leg Holsters position the Glock 19X lower on the thigh for tactical applications or scenarios where belt-line carry interferes with gear, vehicle seating, or body armor.
Chest Holsters serve outdoor activities where waistline access is obstructed by pack belts or when hands-free security is required during hiking, biking, or backcountry movement.
Hook & Loop Holsters enable mounting to soft surfaces, vehicle interiors, or platforms without traditional belt attachment, addressing off-body carry scenarios or situations requiring repositioning flexibility.
Belly Band Holsters provide elastic mounting around the torso without requiring a traditional belt, serving users whose clothing choices, body type, or medical considerations make belt-line carry impractical.
Level 2 and Level 3 Retention Holsters incorporate active retention mechanisms (thumb releases, rotating guards, or locking levers) for law enforcement duty use, military applications, or high-security scenarios where passive retention alone is insufficient.
Carry Styles Supported by This Collection
This collection covers IWB, appendix, OWB, paddle, drop leg, chest, hook-and-loop, belly band, Level 2, and Level 3 carry methods. All rigid holsters use advanced polymer construction engineered for heat resistance, dimensional stability, and long-term durability under daily carry conditions.
The Glock 19X is frequently characterized as bridging duty and concealed carry roles. Its full-size grip provides excellent shooting control and quick holster clearance on the range, but this same feature creates concealment challenges that require attention to holster setup, belt quality, and clothing choices.
Users who successfully carry the 19X daily typically invest time in fine-tuning ride height, cant, and wardrobe adjustments rather than expecting immediate concealment success.
Concealment reality: The 19X's grip length prints more than a standard Glock 19, especially in appendix carry or when bending and twisting. Many carriers report cycling through multiple holsters before addressing fundamental issues like belt stiffness, holster angle, and cover garment length.
Well-fitted holsters with proper adjustment allow effective concealment for most users, though the 19X demands more attention to setup than slimmer compact pistols.
Common Fit or Selection Mistakes to Avoid
Assuming Glock 19 holsters will fit:
The 19X's extended grip and Gen5 ambidextrous controls create fit issues with standard G19 holsters. Common problems include tightness around the dust cover, incomplete grip coverage, difficulty reholstering, and interference with the right-side slide stop lever. Only holsters explicitly stating 19X compatibility should be used.
Forcing the 19X into Glock 17 holsters:
While the grip length matches, the shorter 19X slide leaves excess muzzle space in G17 holsters. This allows up/down and side-to-side movement that undermines consistent draw mechanics, changes the pistol's angle on the belt, and can weaken retention under movement.
Choosing minimalist rigs without adequate support:
The 19X's full-size grip and loaded weight (30+ oz) can feel top-heavy and unstable in very minimalist trigger-guard-only retention devices. Fuller-coverage holsters with better attachment points and body contouring typically provide more stability and comfort, particularly during extended wear or vigorous movement.
Neglecting belt quality:
The 19X's loaded weight requires a supportive belt. Overly flexible belts allow the holster to sag or the grip to lean away from the body, increasing printing significantly. Excessively rigid belts create uncomfortable pressure points and prevent natural body movement.
Not adjusting for grip length:
Many users attempt to conceal the 19X with the same clothing and holster positions they used for slimmer pistols, leading to frustration and printing. The 19X typically requires longer cover garments, patterned shirts that break up printing, or adjustments to ride height and cant that differ from shorter-grip models.
Ignoring Gen5 ambidextrous controls:
Holsters molded tight to single-sided slide stops can create rub marks or binding on the 19X's right-side lever. This is sometimes misinterpreted as a defective holster rather than a compatibility mismatch with Gen5 features.
Over-tightening retention screws:
Excessive retention pressure creates harsh draws and accelerates slide finish wear. Proper retention holds the 19X securely during running or vigorous movement without requiring altered grip angle or excessive force to extract the pistol. Using threadlocker on retention screws once properly adjusted prevents the 19X's weight and daily movement from gradually loosening hardware.
When This Collection May Not Be the Right Fit
This collection does not include:
- Glock 19X MOS holsters specifically molded for optics-ready configurations with red dot sights and suppressor-height backup sights
- Light-bearing holsters for weapon-mounted lights (Streamlight, Surefire, or other WML models)
- Laser-equipped configurations (Crimson Trace, Viridian, or other laser systems)
- Shoulder holsters for cross-draw carry or torso-mounted carry without waistline attachment
- Ankle holsters (impractical given the 19X's size and weight)
If your Glock 19X uses aftermarket controls (extended slide stop, magazine release, trigger guard undercuts, or aggressive grip texturing), verify clearance before ordering, as these modifications can interfere with holster insertion or create pressure points during carry.
Users seeking holsters for the 19X with mounted accessories (lights, lasers, or optics) should verify that compatible configurations are available before ordering, as this collection supports the standard 19X configuration only.
Safety reminder: All holsters for the Glock 19X must fully cover the trigger guard, maintain rigid structure that prevents trigger contact during insertion or normal wear, and be molded to the pistol's hybrid frame geometry. The longer grip makes the 19X easier to grab under stress, reinforcing the need for secure retention and non-collapsing construction to prevent the pistol from working loose during movement. Slow, deliberate reholstering with visual confirmation of the holster mouth is recommended for all carry methods.
