I went to two of our gun shops today to buy a lower for my next AR build and while I was there I was looking for another HK USP 45 for the wife. They said they were on back order from the factory. I thought that was funny. Until I went to the other store and they said the same thing but it's was just not HK the owner told me it was alot of other manufacturesthat are going through the same thing. I was wondering if anyone else is having the same problem.
