I have a set of new/used green night sights for the HK USP . I had my business partner order these and see if they would work on a gun with a can. he put the rear one partially on (against my wishes) and in the process put a minor dent on one side. The front one was not installed. These were fresh night sights and never used. The rear sight is not missing any finish, only the minor dent. I will let these go for $45.00 shipped.
