Leo Decaprio, and the guy who played the colonel both have USP's. Leo's is a compact.
If I remember correctly. Danny Archer hands the bartender the cash who then counts it looks up and says "So.. you want sumting nice eh?"Just saw the movie 3 days ago. when he asked the guy at the bar to find him a gun, he asks for the best he can get. And they guy delivers a USP compact 9mm.... ;-)
