I just bought a NIB USP Compact .45 for $710 shipped from CDNN. No night sights. Is that a good deal? I know it's cheaper to get it used but sometimes you don't know what the actual condition is on the pistol especially from across the country. I was also wondering how to get a match trigger on it. How about an LEM Match? Whats the difference? If I convert to LEM it would put the trigger to 4.5 lbs? And where can I get decent night sights?
