Well the Mateba failed, the only thing that appears different is the flat cyl. Knowing Chiappa, it will be priced cheaper.
But beware, Chiappa has a very bad reputation in the Cowboy world with their 1873 replicas with horid actions and luring unsuspected buyers in with great prices. Even the top Cowboy Smiths seem to can not turn one into a true "race gun" that the gamers need.
