A well worn Wby MkV is definitely smooth. Regardless of what you may think of plastic, the Tikka T3s are pretty dang slick as well.
I burned up a 300 tube on one... started as a fibermark, has a new barrel on it. Its still far from anything I'd call smooth.
But I still base smooth off the Colt sauer and would like to know if anyone has compared side by side a Colt and the others mentioned as being slick....
I will buy something one day and likely a Colt.
have to replace the guns I lost in the boating accident anyway.
