Their holsters are definitely better than every other holster used. They need to however make one for Gen 5 Glock 20,Atlas guns and stucaddos
Fits perfectly. Concealment wing adjustment is a nice feature and I really appreciate all the clip options.
I’ve carried for years, both professionally and personally, and let me tell you—gear matters. You don’t realize just how much until something chafes, shifts, or straight up fails you when you need it most. That’s why I’ve got to give credit where it’s due: the Four Brothers Holster for my Glock 19 is the real deal.
First off, fit and retention are on point. No rattling, no loose draw, and no wrestling it out of the holster either. It holds the Glock snug like a custom glove but still gives a smooth, confident draw every time. You can feel the precision they put into the molding—this isn’t a slapped-together piece of kydex.
Comfort-wise, this thing rides close and low-profile. I carry IWB, and it disappears under a T-shirt with no printing, even for a guy who’s not exactly built like a runway model. Whether I’m walking, driving, or sitting for hours, it doesn’t dig or shift. That’s not something I can say about every holster I’ve owned.
Also, props to Four Brothers for their build quality. This isn’t some mass-produced junk; it’s durable, well-riveted, and the finish is clean. They clearly know their way around concealed carry design. Even after daily use, the holster looks sharp and functions like new.
If you’re on the fence, let me be clear—this holster is worth every penny. Whether you’re carrying professionally or just exercising your rights like any free American should, the Four Brothers Holster is a no-BS piece of gear you can rely on.
I had high hopes for the holster, and my hopes were met with outstanding results, the finish of the holster Came out great. And the fitment is more than ideal. I especially appreciate the multiple levels of adjustment! For everyday fitness/work iwb carry. Fourbrothersinc is who i recommend for any holster purchases.
Locks great
