I bought this because I wasn't entirely satisfied with this holster, also sold by this vendor - https://www.amazon.com/gp/product/B07NQ9G146
The beef I have with the holster this one replaces is that the rubber o-rings that act upon the collet system to secure the flashlight have a problem with coming out of their channels when brushed against lightly, especially when worn on my belt while driving, and interfering with and otherwise causing problems.
The collet type holster required me frequently having to take it off of my belt to reposition the o-rings in their channels, causing so much frustration that I decided to switch to the one in this review.
I've been carrying my Surefire Fury Intellibeam in this new holster for just over a month of heavy use, and I'm happy to say that I'm very pleased with it.
I was at first unsure whether this holster would fit the somewhat larger dimensions of the Fury Intellibeam (1"/25.4mm barrel, and 1.375"/35mm reflector), but it turns out to fit perfectly once the clamp adjustment screw is opened up all the way before carrying this flashlight.
Once that was done, I've had no problem at all easily carrying my flashlight at work, often unholstering/reholstering the flashlight several times each night at work.
I really like the clamping mechanism, which allows a smooth and easy release for the flashlight and an equally easy reholster.
It's also very important to explain that the clamping mechanism is adjustable via a small knurled screw that either opens up or closes the clamping jaws to accommodate flashlights of various sizes, so the first time user would be well advised to set that screw first to fit his specific flashlight before wearing it each day.
I should also say that I had to open the clamping jaws all the way to fit my flashlight, so I can honestly say that it would be impossible to fit anything with a barrel larger than the 1" that my Fury Intellibeam has.
I also really like the belt clip, which is really good at keeping the holster from sliding around much, plus it allows the holster to be rotated a full 360 degrees, 45 degrees at a time, so that will make it possible to do everything from carrying the flashlight in the normal vertical orientation with the reflector pointing down, to horizontal with the reflector pointing either forward or backward, to carrying vertically with the reflector point straight up, or at various angles in between.
Really, the only weak point (largely hypothetical) would be if the clamping mechanism were to get caught on something, especially if the user were crawling, such as moving through a crawlspace or other confined space, but I have yet to have that problem, but I haven't yet worn it while crawling.
This is now my everyday carry holster for my Surefire, and I highly recommend it to anyone wondering about it.

It is a very good holder for your flashlight

It fit my department issued flashlight. It has a latch to help secure the flashlight however, while on patrol i find the latch opening up and me having to close it again, but i will say that the flashlight has never fallen off of my belt. I would recommend this holster

Stays on duty belt where I place it. Flashlight is easy to remove and replace.

It holds my light securely, but the loop for my duty belt feels cheap and flimsy. There is also no way to adjust for different width duty belts, so it may wobble side to side if the belt is too narrow. Overall, a decent value and one I'd recommend
