Dixie Gun Works sells Pietta, Uberti and a couple other well known and good makes of BP firearms.
I have 3 Palmetto revolvers.
One is a brass frame Colt 1851 Navy, what would be a Confederate copy, most similar IIRC to a Augusta Machine Works. When it arrived it was missing the screw in the front of the trigger guard, which was replaced by me with one I had on hand that fit. It works fine otherwise, but the bluing lacks the luster of better-made guns. It appears roughly equivelant to old "Armi San Marco" revolvers; a brand that is no longer seen.
The second is a repro of the Eli Whitney .36 Navy. Now, it works quite fine and everything, and the bluing luster seems good. The wood grips are what can only be described as "Pimply" and a bit uneven, but functional. Now, here it is short what might be found on Uberti.
The third is a repro of the Colt Roots Revolver. The cylinder indexes but is a little loose sideways, and the barrel is a tiny bit off-kilter. The sight is a tiny bit off to a side ... but this curiously doesn't effect accuracy... mainly because by the time there's anough distance to target it just isn't very accurate to begin with. It's .31 cal. The thing is a mechanical menace to get apart as replacing the cylinder is funky, the device that the bolt locks into is not part of the cylinder and can be replaced in a way that allows the cylinder to index exactly 1/2 way between cylinder. It's 50/50 to get it right! But this is a design flaw in the revolver itself, IMHO.
Original Roots had a engraved cylinder, lacking on the Repro.
Now, I have heard enough about Palmettos to be quite suspicious. If I wanted a Colt 1860, a Navy 1851, Walker, I would absolutly say go with Uberti, or Pietta. But they don't make an Eli Whitney or Roots and Palmetto does. I think the Eli Whitney is pretty good inspite of the less than stellar wood. The Roots .... OK. But I wouldn't pay that much again, really, and if Uberti made one I would grab it definantly.
The brass 1851? Well, that was a gift ... but hey, it works, and if I need a gun I don't mind gets roughed a bit for some reason I will take that first.
Palmetto is a gamble .... and the cheap ones may be worth it, the more expensive ones ... it's your money and risk, I can't advise you you must decide your risks based on your assets.
