Taurus Gaucho fail to fire

mountainman888 and all,
Thanks very much for all the advice. I determined the problem and fixed it myself in about 30 minutes. Hopefully the following may assist any others with the same issue. First, I'm not a self-proclaimed gunsmith, however, I did grow up (thank God) on a farm around guns (we hunted a lot, still do...). Many years ago early in my career, I did some precise machine work. So I am mechanically inclined, additionally I have an engineering degree (but don't use it in my job...I'm a career military officer). OK, enough about me back to the gun!
The firing pin protruded further in with the hammer held back, trigger pulled, and me pressing the transfer bar as far forward as it would travel with my finger. Since the pin protruded futher this way as opposed to just letting the hammer push it, I figured there had to be something up with the hammer itself. Upon further observation, I noted that while looking straight down at the top of the lowered hammer that it was not quite square against the face of the rest on top of the pistol frame immediately below the rear sight groove. The hammer itself was square in the frame, but the striking face of the hammer at the very top was not squarly MIMed or machined (not sure which). Looking from the top, the left top hammer edge was hitting the pistol frame not allowing the hammer to fall fully forward against the transfer bar. This was verified by a corresponding wear mark on the frame. I took my dremel and very, very slowly with a soft brown stone, I squared the top hammer edge. Standing behind the pistol and looking down at the top, I held the dremel in my left hand and worked the high spot down until it was square to the hammer sides. Don't attempt to hold the dremel over the top of the pistol and work across the hammer left and right...This could end up giving you a concavity in the hammer face. From the side, work the dremel up and down just on the edge as if you were trying to round the top edge off. I took no more than a few thousands off and progressively finish sanded the edge back to a low mirror shine. The tiny area of repair actually blends well with the case hardened look of the hammer. That fixed the problem and now the pin is definately striking the primers deeper more in line with my other wheel guns.
This appears to be a minor quality control issue at Taurus, not necessarily a design issue. I'm happy with all the Taurus pistols I own, although I have seen similar minor quality control issues on some of my other Taurus pistols. So far, this is the only Taurus pistold I have had any functional failures with however. I imagine Taurus repair backlog will go down if they do a better job qc'ing their pistols before shipment.
