10 Best Concealed Carry Holsters 2026 in the United States

The Alien Gear Rapid Force Level 2 Slim Holster is specifically designed for a range of Glock pistols with large lights attached, making it an excellent choice for carrying a Glock equipped with a tactical light. Made from durable polymer, it provides strong retention through its Level 2 locking system, which balances secure retention with quick and intuitive drawing—important for fast access while keeping the firearm secure. This outside-the-waistband (OWB) holster uses a locking belt slide and supports easy swapping to other carry options such as paddle or drop-leg setups, adding versatility.

Polymer holsters like this one are generally lightweight and slim, aiding in concealment despite the larger light attachment. It is compatible with many popular weapon lights and rear-mounted red dot sights, expanding its usability. However, it is right-hand only and does not fit some optics like the Trijicon SRO or forward-mounted sights, which may limit options for some users.

The holster’s design is duty-rated and field-tested to handle active lifestyles such as hiking or outdoor work, where durability is essential. While OWB carry and the large light profile reduce discretion, its slim design helps minimize printing under clothing. The locking mechanism enhances retention confidence but may require some practice to master a smooth natural thumb swipe draw. This holster suits Glock owners who prioritize secure, reliable carry with large lights and possibly an optic, emphasizing retention and draw speed over maximum concealment. Those needing ambidextrous options or ultra-concealable inside-the-waistband carry should consider other models.

The Safariland 6378RDS is a well-made concealed-carry holster designed especially for Glock 19 and 23 models with a Surefire X300U red dot sight. Its plastic construction with a SafariLaminate thermal-molded design and suede interior offers durable protection without adding much weight, which is helpful for all-day comfort. This holster offers versatile carry options through a paddle attachment and a standard belt loop, catering to users who want flexibility in how they carry.

The standout feature is its Level Three retention system using the Automatic Locking System (ALS), which securely locks the firearm in place but allows for a smooth draw with a thumb swipe. This balances safety with quick access, important for both everyday carry and duty use. The holster is specifically designed to accommodate a red dot optic, making it a good pick if you use this sighting system. The protective cover for the optic rotates away when drawing, helping to avoid snags.

Regarding concealability, the design is compact and should work well under most clothing, although the paddle attachment might add slight bulk compared to slimmer inside-the-waistband holsters. Some users might find plastic less comfortable against the body than leather or hybrid materials, but the suede lining helps with comfort. For those seeking a secure, durable holster that offers a quick draw and fits a red dot-equipped Glock, the Safariland 6378RDS is a solid choice. It especially suits those prioritizing retention and optic compatibility, though if maximum concealment or minimal bulk is your goal, there may be slimmer options available.

The Alien Gear Photon Holster is a flexible option for Glock owners looking for a holster that supports multiple models (Glock 17, 22, 47, and others) and carry styles. Made from durable materials like Kydex or Boltaron, it offers good retention to keep your firearm secure. One of its standout features is ambidextrous design, allowing left- or right-hand draw setups, plus it works both inside- and outside-the-waistband, catering to different comfort and concealment preferences. The holster fits a variety of weapon lights, including popular models from Streamlight and Nightstick, which is a big plus if you carry with a light attached.

You can also customize the cant (angle) and ride height for better comfort and quick access, which helps with draw speed. Additionally, an optional sidecar attachment lets you carry an extra magazine nearby for fast reloads. On the comfort side, the modular hardware for different carry positions helps, but some users might find the holster a bit bulky compared to simpler designs. Concealability is good for an adjustable holster, though those seeking ultra-slim profiles might want something less adjustable.

The retention is solid, but fine-tuning may be needed to balance security with smooth draw speed. This makes the Alien Gear Photon Holster a versatile, well-built option that suits users wanting adaptability, especially those who carry with weapon lights and want options for carry position and hand preference.
