You are looking at a very high quality Sickinger Holster, (expert model) made in Austria for the HK USP 9mm Compact.
Bought the holster, but never used it. See the Sickinger site for details at - - - sportshooter.de/en/holsters/for_pistols/sickinger_holster_expert.htm)
In perfect condition, as brand new, in the original packaging but since I opened the package, tried it on my belt and had my HK in it, it is marked as used. HK pictured in the photos is for demonstration of the holster fit and is not included
