Alien Gear Photon Holster for Glock 43 Series - Ambidextrous

In this review of the Alien Gear Photon Holster, the bottom line is simple: this is a versatile, comfortable carry option for Glock 43, 43X, and 43X MOS owners who need an ambidextrous, optic-ready holster without a mounted light. The holster's modular design and customization for cant, ride height, and sight setup make it a practical choice for daily carry or duty use, and the review finds its best asset is adaptability across IWB and OWB positions while keeping a slim profile.

Key Features

• Ambidextrous design: Converts for left or right hand draw so a single holster can be repositioned for different users or hand preference.
• Optic-ready, no-light fit: The Photon supports most standard optics and closed emitters, allowing owners to keep an optic without compromising retention when no weapon light is mounted.
• IWB or OWB carry: Configurable for inside or outside the waistband and multiple carry styles including appendix, strong side, and drop leg for user preference.
• Customizable cant and ride height: Fine-tune the draw angle and position for comfort and a consistent presentation with suppressor-height sights.
• Made in the USA: Construction and finish reflect a focus on durability and professional-grade performance for everyday use.
• Modular expansion: Accepts an optional sidecar mag attachment to increase on-body reload capacity without swapping gear.

Who It's For

The Photon holster is best for Glock 43, 43X, and 43X MOS owners who carry their pistol without a mounted light but want to retain the ability to mount a compact optic. It suits users who value a slim, adaptable platform that can move between IWB and OWB carry and those who need ambidextrous setup for shared or left-hand use.

Prospective buyers who always run a weapon light should look at the Compact Light version instead, as this no-light Photon is not intended for pistols with forward-extending lights. Users demanding a factory-perfect fit for every aftermarket accessory may also want to verify fit for specific optics before purchase.

Pros & Cons

Pros

• Solid build quality and comfortable for extended wear thanks to a slim, modular profile.
• Flexible carry options let users switch between IWB and OWB and adjust cant and ride height easily.
• Optic-ready cut supports most standard optics and closed emitters while maintaining retention for no-light setups.
• Optional sidecar provides simple expansion for extra magazine storage when needed.

Cons

• Fit and retention received mixed feedback from users; some report tightness in OWB setups and others see it as secure, so break-in and adjustment may be required.
• Not compatible with pistols carrying a forward-extending weapon light; the Compact Light version is required for those setups.
