Look on top of the barrel if you're looking from the hammer end of the gun. Is there a proof mark on the rear of the barrel towards the receiver on the left side or right side? If its on the left side, can you please tell us the date the firearm was made? My 1894CB was extremely smooth out of the box but it was also made right before the remington/freedom group take over.
EDIT: If you do want a simple fix to the problem, take some 600 grit sand paper wet or dry, some gun oil, and some chrome polish and polish all contact surfaces, or take a knife sharpening finishing stone, or fine arkasas stone and some honing oil and give all the contact and mating surfaces a good polish. You don't want to polish all the bumps and stuff out, you just want to smooth each part out making them all even and true. After that clean the gun and apply chrome polish to the exposed areas of metal.
