Not to down your new purchase, but I have noticed that Pietta does not put nicely figured "European Walnut" wood on their pistols these days; rather it is quite plain. I bought a Pietta 1851 Navy steel .36 just after Christmas from Cabela's in 2014 (date code [CM]) with rather plain wood (I have since used that wood to create a Clint Eastwood silver rattlesnakes grip), and desired a better figured Pietta piece. I found one on Ebay for $38 but it is some sort of hardwood with very nice figure. IMO, the folks that sell parts on Ebay go to Cabela's (or others) and sort through their stock and find the best looking revolvers and part them out. I do not believe any attention is paid to barrel/cylinder gap, etc.: that's up to the purchaser, and that's pretty good for scroungers like me looking for wood, barrels, cylinders, wedges, et al, and prices are slightly above or equal to or even less than parts obtained from VTI, Taylors, or others where you have no idea what you are receiving insofar as appearance.
Good luck in your endeavours.
Myself, I am waiting for Cabela's to put the Pietta Griswold and Gunnison .36 on sale around the holidays. At $220 now, it is still not a bad deal.
With the addition of that pistol to my Pietta 1851 Navy squareback (with a possible addition of my spare large round TG) I can create at least five pistols (with a few fantasies using the squareback TG: Ashley @ Taylor's may possibly procure a squareback TG if you desire):
1851 Navy Squareback 2nd Model .36
1851 Navy 3rd Model .36
Griswold and Gunnison .36
Schneider and Glassick .36
1851 Navy Squareback Dragoon .36 (Fantasy)
I am also looking to purchase a spare 1851 Pietta barrel to cut down to create an "Avenging Angel" model.
One of these days these guns/parts will go into a huge wood presentation case if the money holds out.
Ad nauseum
