Some are and some aren't. TC's barrel tolerances have beenfairly largein the past. I don't know if they have done anything to improve consistency or not. The .45 Encore I have left is a very tight .450 while a blue one I sold was just over .451. My G2 .45 barrel is also just over .451. The .45 Encore barrelremaining was a replacement for a poorly done 1:20 twist SS barrel that wasprobably .452.

Seems to me (based only on my own limited experience) that TC's blued barrels tendnot only to bemore consistent dimensionally but are/have been better barrels generally when compared to their SS offerings.
