PHLster kydex holster.
As being fairly new to Glocks in general I did several months of looking around and reading reviews of different style holster from different manufacturers, even trying several out at the range, and finally settled on a holster from PHLster (a small family owned company out of Philadelphia that makes all of their products as ordered). Now I will say now that I do not know if anyone has already posted about PHLsters and if there has been posts regarding them in the past I apologize now. With that said and out of the way. I purchased the Skeleton IWB holster from PHLster and could not happier. Its kydex and has a single snap loop for securing it to a belt as wide as 2 inches and you can adjust the height that the holster "rides". I IN MY OPINION, I feel that the retention that it offers is adequate, not too much to prevent a quick draw, and not too light as to permit the firearm from falling out or coming loose while under normal wearing. It is very comfortable as well, I have had it on most of the day while running around the house getting the "honey do" list done and have no complaints about pinching or poking. I have attached some pictures so you can get an idea of what it looks like.
Price shipped: $45.00
Wait time: Website states 4-6 weeks I had it in a little more than a week.
Overall I am very pleased with the quality of this holster as compared to others I have tried, and helping out a smaller company is always cool in my book.
If you havent already, give them a look at PHLster.com, they make several other products.
