I have a bladetech that came as a modular system with a locking clip for belt usage, a drop extension for tacticalthigh usage, and a paddle. A very good holster, what can i say its a bladetech, and if you consider all of the options it was a bargain to boot.
The only complaint i have about it is that if i use it with my G35 without the light its loose. I can still use it for a class or range use but nothing where i might be rolling around.
I believe uncle mikes has something too.
