I recently bought a USP 45 with a KF date code. The owner estimated 5-7000 rounds down range. The barrel hood is shiny silver like the barrel hood of a Sig P226. The rest of the barrel and the sides show wear but aren't silver/shiny. Did any USP 45's come with a shiny barrel hood from the factory? As I'm in California I have to wait 10 days to pick it up so I can't look at it right now but is it possible this USP45 has a conventional barrel rather than polygonal since it was an early USP45 or did all USP 45's come with polygonal barrels?
