Prices tend to be volatile due to dollar/euro fluctuations. They range from $181 at EMF for a gun of unknown manufacture to $291 at Midway for a Uberti (remember, these are standard guns, no special finishes, etc. You can pay more...). The least expensive Pietta is $200 at Arms2Armor, although 3 others offer a $210 Pietta (watch shipping/handling prices carefully). The least expensive Uberti is $225 at S&S, with $235 at October Country and $237 at Buffalo Arms the next highest. Texas Jack's $246 gun is actually a Cimarron (Uberti) and is a good value if they have it in stock.
