Imitation is the best form of flattery. But instead of feeling flattered, you just sound bitter. For what it's worth, Andrews design has straps over both shoulders with a butterfly plate between the shoulders and a horizontal strap across the lower back. I don't see the similarity to the x2000 and x2100 or the newer x15 unless you mean just the shape/design of the spring-retention holster.

Do you really expect every new craftsman to reinvent the wheel for the sake of originality? Most holsters are just slight variations on designs that have stood the test of time. And those designs were most likely inspired by long-since forgotten sources. Andrew's Springbreak holster works well and is very high quality. As a holster buyer, what more could you ask for?
