Will this work for you? - Gould & Goodrich BootLock Ankle Holster for Backup Gun

Got this to carry a BUG on duty in uniform. Problem is, the uniform pants are tailored such that it prints a nice gun-shaped lump under the polyester-wool blend--zero concealability--and when you sit down the pants ride up, get snagged on the holster, and then won't fall back down again, thus exposing the gun when you get out of the car. Verdict for the uniform: Completely useless.

However, it worked perfectly under wide leg jeans, boot cut pants and stiffer work pants. Very stable platform--once you get it laced into the boot, which is a pain--and securely holds the gun even when running. Verdict for pants other than those I actually bought it for: Terrific!

So be prepared to spend a while getting it properly laced up, but once you do it will be a good solid, stable and secure holster. Biggest issue isn't with the holster itself, but what pants it will work under. Most uniform pants just won't work.
Pros: Solid, stable
Cons: Pain to set up, won't work in all situations
