The thumb break strap is very stiff which is like any other holster once you get it broke in and the holster molded to your gun it is like a glove. Works great with my Glock 21SF W/ TRL-1 tac. light. The scuba webbing on the leg straps keeps the holster in place even while running instead of trying to run around your leg or bouncing around while droping to the prone position. An infinate aray of carry positions drop-leg,belt,mole vest,R OR L mount. Even has an adjustable pistol depth.
Pros: many carry positions
Cons: super stiff thumb break strap.
