Quite a bit of people complaining it does fit their light, so lets makes this very clear. This particular StreamLight Holster if for a "STINGER" Streamlight, Not STRION, not the small pen lights, and NO OTHER BRAND unless you get lucky. It fits my Stinger perfect and is very sturdy, and doesnt slip out because it has a built in spring clip to hold it in. It comes out very smooth, and doesnt wiggle around when your working.For the price compared to my $200 Stinger, $17-18 for a sheath is absolutely amazing and worth it. Didnt fall off my belt one time today and I work on small private planes in very tight spaces.Fits like a glove. Have been using it for my streamlight flashlights and it is so snug and won't fall out. Easy to pull out too. Belt clip is good quality and unless you get hit by a car, it shouldn't fall off. I recommend this item for your streamlightThis holster lives up to its reputation. I have it hanging on my backpack, which I use daily at work. The flashlight never falls out and the holster holds up to the bumping around that comes with being attached on the outside of the backpack.Just wished the best clip was a loop instead of a clip. Holsted does move side to side wich is kinda annoying also sometimes the flash light does slide up, however I has never fallen out on me. Overall condition I love this holster.I purchased this for my stinger to go on my duty belt. The flashlight is secure in the holder but the holder isn't secure to the belt at all. The clip is absolute garbage when it comes to duty use. This thing isn't secure enough for getting in out of vehicles, foot chases, or anything other than that. It fell off multiple time while putting my belt on so I'm worried to say the least.I saw other reviews mentioning this and ways the rigged it to stay on the belt, but for this money I'd go with something more secure. My flashlight costs too much to lose over a rinky dink clip. I'll be returning this for this reason alone.Holds the flash light very well. However the belt clip part is terrible. Does not stay on the belt at all. Will fall off if not glued on or other more permanent “fix”I work on semi trucks and trailers. I have the new 2020 stinger and the old stinger. Does NOT FIT the 2020 stinger only the cop stinger.Good holster, bigger than I was expecting and fits with my ultra stinger perfectly. The holster fits just fine on my Klik belt(1ply) and I so far have no trouble with it coming off the belt or the flashlight being too loose or tight. My ultra stinger comes out smoothly with no issues, but I will say that the holster brings it up a little high in my opinion, but I’ll see if I get used to it over time. When sitting down, the head of the flashlight sits a little past my side and presses in a little, but it’s not too uncomfortable. I’ve seen so many bad reviews about it not fitting on duty belts well and it comes off easily, which I can see why. The clip on the back is a bit flimsy and will come off of a duty belt, which isn’t good. I personally don’t wear a duty belt, but I’ve had one sitting in a box for a long time. Hopefully the photos above will give you guys an idea of what this holster can fit on and what it can’t. It for sure will work with molle and any other belts or straps that are 1ply, it’ll barely make it on a 2ply though at max. So if you’re looking for a holster that’ll fit on a “duty” belt, then I would suggest looking elsewhere, but if you don’t mind just using this on a regular belt or even attaching the holster to molle, then go for it! Just make sure that the model you have will fit with this holster, but it will definitely fit with the ultra stinger, not sure about the new LED models they make now. Hopefully this review was helpful to anyone that may be interested in buying this. It’s actually a real good holster, but I would agree with the others about the clip. Streamlight should make this holster with a different type of attachment other than a basic clip. Oh and the lip inside the holster is plastic(the entire holster is) with a metal spring holding it up to put pressure on the flashlight, which I do think is a great feature so it won’t scratch the flashlight too much, but it’s not like a little scratch will hurt anyone anyways. Have a great day everyone!Excelente sería mejor si el clip fuera ajustable al cinturón desde que se introduce al cinto y no solo de clip se desprende si no es el cinto lo suficiente delgado para que encaje bienGood quality. Appears very robust and will give years of service. DOES NOT FIT MY STINGER tho! It was even a recommend purchase when I bought my light. POOR RATING DUE TO INCOMPATABLE ADVERTISED FITMENT.Boulder fits my flashlightTook a chance and hoped it would fit a PolyStinger DS LED. It does not. DisappointedX
