FOUR BROTHERS HOLSTERS
Couldn't load pickup availability
This Outside Waistband (OWB) competition-style holster is engineered for speed, retention, and reliability. Designed to fit Glock 17 Gen 5 , Gen 6 & Gen V and 47 Gen 5 pistols—or Glock 17 and 22 Gen 3 or 4 pistols—with the Streamlight TLR-1 HL or TLR-1 HP weapon-mounted light, it delivers precision and performance for range or match use.
The holster’s retention is based on the weapon light, not the pistol frame. The TLR-1 HL, TLR-1 HP (or TLR-1) must be mounted for proper retention and draw consistency.
This holster will not work with the TLR-1 HL-X or TLR-1 HP-X light.
Each holster is vacuum-formed from a precision-machined mold based on an exact CAD model of the pistol and light. We form, trim, and fold every holster in-house, and perform final fit and function tests with the actual firearm and light combination to ensure the perfect balance of retention and speed.
The retention adjustment system compensates for minor dimensional variations between older and newer Streamlight TLR-1 and TLR-1 HL or TLR-1 HP models, ensuring a secure fit for all versions. Retention can be easily adjusted to your personal preference.
We recommend applying a removable thread locker to each screw after setup to prevent screw loss during active use. Retention can be fine-tuned with the set screws for your preferred draw strength.

Fit my G17/19 with a light perfectly. Built out of solid material and looks great. It’s my second holster from them and I highly recommend this company to anyone looking for a good holster. Customer service is also top tier.
Using it for both a Glock 17 and a Glock 19 - both fits well and the retention is nice and snug. I got just got the Blade-Tech Duty Drop with thigh strap - the strap has a sticky rubbery texture that adheres well on my thigh so it doesn't move around when I'm running with it. It's open at the bottom so I can fit my attached "Herrington Arms" compensator for both pistols - the compensator is perfectly flush with the Glock 17.
Great quality holster, also got thigh belt attachment and it’s amazing. Feels very durable and fits the Glock 17 great. Can’t wait to use it out on the range

This holster is awesome! Not many options for Icarus precision customizable side cars out there, had never heard of this company prior! Man am I impressed by the overall quality of this holster! Far more adjustable than anything else I’ve tried in this style(Tier1, Trex, LAS). I’m still adjusting to exactly how I like it about 2 weeks in. Only complaint I found is my optic (Swampfox Sentinel 2) did not fit and I did have to remove material around the optic to make it compatible. I know this isn’t a common optic so I wasn’t worried about it at all! Highly recommend you go buy this one
