A friend from work just took me over to look at an HK USP .45 (blued) that he is thinking of buying from one of our local pawn shops. I would like to give him good advice on whether to get it or not but I have no experience with HK so I am here to ask you guys. The gun appears to be in great shape with original plastic box and instruction book. The sights on it look to be three dot night sights and the rear sight says "True Dot" on it which I am not familiar with. I don’t know if they are factory or aftermarket. Asking price is $659 but they will let it go for $600. Any advice about this gun, sights, price etc. would be greatly appreciated. Thanks! Art G.
