Comanche revolvers are made by an Argentine company called Rexio. They used to be really awful, they made some improvements (they replaced the cheap alloy frames with steel) but they are still quite bad.
In the local market, almost no gun store carries them. Although they are cheaper than Taurus, and S&W and Ruger guns cost twice as much as they do in the US, Rexios don't seem to be popular over here.
Plus they only have a 1 year warranty.
