FOUR BROTHERS HOLSTERS
Couldn't load pickup availability
This precision-molded Inside Waistband (IWB) Taco Style holster is designed to fit the Glock 17 Gen 3, Gen 4, Gen 5, Gen 6 & Gen V, including Gen 4 MOS and Gen 5 MOS models. It is also compatible with the Glock 22 Gen 3 and Gen 4.
Please note: This holster is not compatible with the Glock 22 Gen 5 due to design differences in the frame and slide profile.
Each holster is formed using a CAD-modeled Glock 17 and vacuum-formed to ensure proper fit and retention. Slight retention adjustments may be necessary for older generations or frame variants.
Apply a removable thread locker (e.g., blue Loctite) to all screws during setup to prevent them from loosening during daily use.

Q: What Glock models will this holster fit?
A: This holster is designed for the Glock 17 Gen 3, 4, 5, 6 and V—including Gen 4 and Gen 5 MOS—and the Glock 22 Gen 3 and Gen 4.
Q: Will it work with the Glock 22 Gen 5?
A: No. The Gen 5 Glock 22 has dimensional differences that prevent proper fit and retention.
Q: Does the Glock Gen V 17 fit this holster?
A: Yes, the Glock 17 Gen V fits this holster.
Q: Is this holster optic ready?
A: Yes. The cut allows clearance for most red dot sights mounted on your Glock slide.
Q: What does the Modwing do?
A: The optional Modwing applies inward pressure against the inside of your belt to pull the grip closer to the body, minimizing printing. It includes two interchangeable inserts for user preference.
Q: Is the retention adjustable?
A: Yes. You can fine-tune ride height, cant, and retention to fit your draw preference and carry position.
Q: Do you offer matching magazine carriers?
A: Yes! We offer both IWB and OWB magazine pouches for Glock 9mm magazines.
Q: What if I don’t see my Glock variant listed?
A: Please contact us — we’re happy to help you find or build the right holster.

I absolutely love the fit and finish of this holster. I do wish there was a more positive click when the firearm is inserted into the holster but no matter how you adjust the tension it just doesn’t have that loud audible click. It holds the gun securely so that is a minor gripe. Overall this holster is built like a tank with excellent quality, fit, and finish.
