While I like Blade-Tech holsters generally, I find their paddles to be lacking. Specifically, they have only one "hook" as opposed to two, like most paddles. This allows the BTs to pivot fore/aft on the hook, causing a lack of stability unless the belt is severely tightened. I've found that even Fobus holsters are more stable than the Blade-Tech.
I have a Paddle from Ready Tactical
http://www.pistolpacking.com/ that I like a lot. The only drawback it has it that it's double hooks are so stout, I predict worn holes in the belt-line of my jeans soon.
I'd like to try a CompTac paddle or locking paddle. The locking paddle, in particular, looks like it would avoid the "worn-pants" syndrome.
