No experience from Bass Pro.
I believe that guns marketed by Traditions are made by Pietta. At least, the Traditions copy of the 1860 Colt .44 that I bought two years ago was made by Pietta.
Pietta-made guns vary in quality, lot to lot, so I hear.
My own Pietta-made copy of the 1860 Colt .44 is very well made, perfectly timed and nicely finished. Cost me $140, new in the box, at the local gun store. It was a bargain.
It's accurate too.
If you get a poorly made gun, send it back. If they send you another poorly made clunker, send it back. Keep doing so until they send you a decent gun, or until you get fed up and ask for a refund.
Exterior finish is often indicative of overall finish. Check the bore to ensure it is smooth and doesn't have large tool marks. Also check the chambers, to ensure they are smooth and not rough.
The trigger pull can be improved with some careful removal of burrs in the action with a set of Needle Files, but do NOT touch the surfaces where the trigger meets the hammer. These engaging surfaces are very finely mated and should not be touched by amateurs.
But before you start tinkering with the guts, make sure you're going to keep it. Companies won't take it back if you've done even the slightest work on it.
The smoothness of the bore is critical. Degrease the bore with Ronson lighter fluid or brake cleaner. Then, push a bone-dry patch through the bore. If the patch doesn't glide through the bore smoothly, beware. The bore may be too rough to overcome with polishing.
When I get a new cap and ball revolver, I work some JB Bore Paste or Iosso Bore Cleaner into a tight patch. These are creams, containing a very mild abrasive.
Run the tight patch back and forth in the bore a dozen times or so. Then discard the patch and start a new one, with this cream worked well into it. Work it back and forth another dozen or so times.
Do this with 12 patches, for about 144 strokes. By the last patch, you should notice an improvement in the smoothness of your bore.
This preliminary smoothing will markedly increase accuracy if the gun's decently made. It won't do a thing for a gun with a rough bore, full of tool marks.
The bore may also be smoothed by shooting it, but it would take you 500 balls or more to get the same polishing effect you get with 144 swipes from a tight patch, impregnated with Iosso or JB Bore Paste.
The JB comes in a small, white plastic tub. The Iosso comes in a squeeze tube. Both are very good products. Look for them at your local gun store.
