I doubt it will shoot 9x23 Winchester. I had a Medusa, it cost me about $700 IIRC but I opted for the "ploymer" finish which added $100. So the gun was around $600 or so. It was a good enough revolver but the metal work was not what I expected. It wasn't bad really, but the edge of the recoil plate have a dent where metal was displaced before finishing and was not fixed, so it was quite and eyesore.
The Medusa used a neat extractor star that had little ears that slipped under the cartridge rim, this is how it accomodated all of those calibers. I do not know how the Taurus Triad is set up but if it is a similar set-up it will do all of the calibers of the Medusa. Medusa advertised 28 cartridges or so but many of them were obsolete, unobtainable or extremely expensive due to scarcity. I used 9mm, .38 Special & .357 Mag the most. I broke the special extractor set-up b/c I shot some 9mm first and then went to .38's or magnums so the cases stuck in the cylinder due to fouling in the cylinder from the shorter 9mm's. They say to fire the longer cartridges first, which I know is best but sometimes you just do what you do. Anyway, they say not to force the ejector rod, which I did, but not that hard and it broke one of the ears on the extractor. By this point, Medusa was no longer selling guns, but was still doing warranty repairs. I sent in my cylinder and they fitted a new extractor star for a decent price.
In talking to the owner he told me that he got out of the gun business because he wasn't a gun guy amd didn't like all of the hassle, ie. ATF, customers messing stuff up, etc. I believe he was an engineer and went back to that. He sold his remaining frames and parts to one of the customer revolver smiths who's name escapes me now. If you search here for my name & medusa I have a link to it in a prior post. It is called the Scorpion now and goes for either $1200 or $1600 I can't remember now. Of course it is a much nicer finished product, but not that nice IMO.
Anyway, my whole point in posting was about 9x23 Winchester. Medusa had published that the Medusa was "already chambered for this new caliber before it was introduced." I bought a box and it would not chamber. The 9x23 Win is a tapered base and is too fat at the base. I would imagine that the Taurus will have the same problem. Dane Burns was converting S&W 940 9mm Centennial revolvers to 9x23 Winchester (which he stopped doing due to safety concerns) and he said that .357 Magnums could be fired in it after the conversion, but that the brass would not be reloadable because it would bulge the case at the base due to the 9x23 being thicker at the base.
