Anybody use the Safariland 2" drop adapter for their belt holsters? Specifically the 6377 ALS holsters?

Does this compare at all to the Blade-Tech DOH holsters?

I like the way these DOH holsters sit on the belt and would like to try this drop kit on my current holster before buying the Blade-Tech.
