I have been VERY happy with this holster!
Crossbreed vs. Garrett Silent Thunder IMO:
Both equally tuckable
Both equally stable(Surprised me as the ST has only one clip)
Both cant
Both are VERY secure and adjustable
The ST:
A bit less comfortable - The leather is on the INSIDE to protect your gun, not your side. Nonetheless, I've adjusted well and quickly to it and it is VERY comfortable.
Crossbreed Mini Tuck:
More comfortable - A lot larger area of contact, but the kydex is rough on even the DLC finish.
