Collection: Custom Holsters for Glock 45 | IWB, OWB, and Duty Options

The Ultimate Glock 45 Holster: Engineered for Unmatched Safety and Everyday Confidence

The Glock 45 is a pioneering crossover pistol, merging a full-size Glock 17 frame with a compact Glock 19-length slide. This unique blend offers superior control and faster sight acquisition, but it demands a holster engineered specifically for its distinctive geometry. 

At Alien Gear, we craft Glock 45 holsters with precision molding to ensure flawless fitment, secure retention, and unparalleled comfort — every single time you carry.

Custom-Fit Design for the Glock 45's Unique Profile

Unlike generic holsters designed for the Glock 19 or Glock 17, our dedicated Glock 45 holsters are sculpted to match its full-size grip and compact slide configuration. A holster that doesn't honor these exact contours risks poor retention, uncomfortable hot spots, and compromised safety. 

Our American-made holsters eliminate these pain points by providing a precision-engineered cradle for your Glock 45, protecting your trigger guard and supporting confident reholstering without distraction.

Tailored Solutions for Concealed and Duty Carry

For concealed carry, our Glock 45 IWB holsters deliver deep concealment with unmatched comfort. Options like the Cloak Tuck 3.5 and Shapeshift appendix carry holsters feature adjustable cant, ride height, and passive retention, allowing you to dial in the perfect balance of security and accessibility. 

The Photon line also supports optic-ready configurations for Glock 45 MOS models, ensuring a smooth, snag-free draw — even with a mounted red dot sight.

Need a slimmer profile? Our Low-Pro IWB holster offers minimalist design without sacrificing durability or stability, reducing printing for discreet everyday carry.

Optimized for Appendix Carry Comfort

While the Glock 45's full-size grip offers excellent control, it can pose concealment challenges in appendix carry. Our AIWB holsters integrate concealment claws that rotate the grip inward, reducing print under fitted clothing and enhancing all-day comfort for professionals, plainclothes officers, and dedicated concealed carriers.

Light and Optic-Ready Configurations for Tactical Advantage

Our Glock 45 holsters are purpose-built to accommodate weapon-mounted lights and optics. Whether you're running a Nightstick TCM-550XL, Streamlight TLR-7A, or a Trijicon RMR, our holsters are molded for precise compatibility. These holsters maintain full retention and draw efficiency, even with mission-critical accessories attached.

Superior OWB and Duty Carry Options

For open carry or range use, our ShapeShift OWB paddle and belt slide holsters offer robust modularity, easy adjustment, and exceptional comfort. 

Professionals seeking advanced retention systems will appreciate our RAPID FORCE® Duty Holsters, which feature Level II and Level III retention options with thumb-release hoods and locking levers — ideal for law enforcement, military operators, and high-security scenarios.

Versatile Configurations for Every Environment

Whether you're moving between concealed carry and the range, our modular holster systems (like the ShapeShift Core Carry Pack) allow seamless transitions from IWB to OWB, appendix, or paddle configurations using the same shell. This consistency in drawstroke and feel builds true muscle memory, empowering confident performance in any setting.

For outdoor adventurers, our chest holsters and drop-leg rigs keep your Glock 45 secure and accessible while hiking, riding, or working in rugged terrain. These setups free up waistband space and integrate seamlessly with packs and body armor.

Left-Handed and Specialized Options

Our commitment to every user means offering left-handed holsters across all major lines, including the Photon, ShapeShift, and Cloak series. You’ll enjoy the same adjustability, robust retention, and ergonomic excellence as right-handed configurations.
