Actually, it has the higher rear tang contour of the Orange and Czechmate, comes with the larger mag well of the aforementioned, as well as the adjustable rear sight, hammer, aluminum grips, fiber optic front and fuller underlug of the Orange, and is all-black frame/slide. The reason why I got it is those were all things I would have added to (or at least liked over) the regular TS. So for what I got the TSB for, it's closer to how much I would have to spend on the regular TS, but with a (to me) nicer grip tang and slightly heavier frame....and (at the time) much easier to find and less expensive than an Orange.
