10 Best Iwb Holsters 2026 in the United States

The Alien Gear Photon Holster is a versatile option designed specifically for Glock 43, 43X, and 43X MOS pistols without mounted lights. Made from durable plastic, it offers solid retention with a snap closure that keeps your firearm secure while allowing quick access. One of its main strengths is its ambidextrous design, making it convenient for both left- and right-handed users. The holster can be worn inside or outside the waistband, giving you several carry style options such as appendix, strong side, or even on a drop leg.

Adjustability is a strong point here—you can fine-tune the holster’s cant (angle), ride height, and sight setup to improve comfort and speed of draw, which is especially helpful for all-day wear. It also supports suppressor-height sights, a nice feature if you use those. The holster is optic-ready for most standard optics that don’t extend beyond the mounting plate, but it does not fit pistols with mounted lights—if you need light compatibility, a different model is required. Comfort-wise, the slim and modular design aims to minimize bulk and irritation during prolonged use.

A useful add-on is the optional sidecar for extra magazine storage, letting you carry a backup mag securely and within easy reach. If you own a Glock 43 series without a light and want a flexible, comfortable, and ambidextrous holster with optic support, the Alien Gear Photon is a solid choice.
