I am a huge fan of the Dakota Defender by K&D.

It is stable, well made, comfortable, adjustable and even tuckable. Multiple clips are available for different size belts, even C clips or J clips for better concealability. If you wish you can have it made out of exotic material but the plane jane version which I have is only $70. Wait is 14-16 weeks and worth it.
