The main problem with Kydex holster was essentially eliminated when makers stopped making the belt loops and other attachments of Kydex. It's great for the body of the holster, but prone to failure when exposed to repetitive stress, even when it's thick material. Injection molded belt loops and clips made a huge difference in durability of the holster as a unit. I still prefer straps, though, preferably made of something similar to Daltech BioBelts. Leather can't come close to the durability and life expectancy of that stuff and you can't tear it.
