The Best Glock 19 IWB Holster is precision-molded for secure everyday concealed carry. Designed to fit the Glock 19 (Gen 3, Gen 4, Gen 5, Gen 6 & Gen V), Glock 19X, Glock 45, and Glock 32, this premium Kydex Inside Waistband holster delivers excellent retention, all-day comfort, and a slim profile that minimizes printing. It is also compatible with Gen 3 and Gen 4 Glock 23 pistols. Please note: this holster is not compatible with the Gen 5 Glock 23.
Each holster is vacuum-formed using precision CNC-machined molds and fit-tested with the actual firearm to ensure consistent retention and safe performance. Every holster is molded using a Gen 5 Glock 19 as the reference firearm. Gen 3 and Gen 4 pistols fit securely, although minor retention adjustment may be desired for your preferred draw.
This Glock 19 IWB holster is engineered for all-day comfort and dependable performance. Its low-profile design helps reduce printing while maintaining a consistent draw stroke. Adjustable retention and cant allow you to fine-tune the holster for appendix carry, strong-side carry, or your preferred concealed carry position.
Built from premium .093-inch Kydex, every holster is precision vacuum formed using CNC-machined molds and individually tested with the actual firearm before shipment. The result is repeatable retention, durability, and a secure fit you can rely on every day.
After adjusting your preferred retention and cant, apply a removable thread locker such as blue Loctite to all screws to help prevent hardware from loosening during daily use.

Four Brothers are my go to for holster. Amazing quality and pricing.
Still have not received
Oscar, the delivery failed, and the package is on its way back to us. We typically see this when there is an address issue. We will reach out to you once we receive the package to arrange delivery.
See my 43X post too. Best slim fit, best comfort. Wont pooch out. Monoblock rocks!
It works with my Gen 5 G19 and slightly worse with my Gen 5 G26. I like the color, the hardware placement is good, the holster does a good job of staying in position throughout the day, and I like the design. However, it doesn't have the "click" I like, and with my G26 it feels more like I am shoving it into a tight space for retention rather than having a firm grasp.
Overall, I think the holster is "just fine." It's just slightly better than the $50-60 holsters I have, but not enough of a deal that I would choose this over a Tier 1, TRex, LAC, etc., for a few more dollars.
Great holster what I was looking for. Easy to adjust and very comfortable
It fits the 6 inch warrior, although it leaves the muzzle exposed obviously. Good quality holster for outdoor use. I wrapped mine (poorly) in 500D cordura. Wish they made one for the long slide.
