Atlaw, I've been reading this thread and although I'm a bit slow, I might be able to give you a couple of ideas concerning concealed carry. You are right about needing an IWB holster, especially for a larger gun. The trick there is to buy your pants one size larger than you do now, to give the gun room in there. Also try wearing it either ahead or behind your hip bone. At 2:00 o'clock or I carry mine just a little farther back than 5:00 o'clock. Hope this helps you enjoy that gun more.
I have three Taurus (all .45 colt) and two have been great. The third one was finen but had a bad trigger pull and did not quite line up the cylinder with the loading gate on half cock, but that's an easy fix and I have had many of those same issues with other brands. Anyway I called Taurus and told them my objections and they said to send them the gun. I got it back in about 3 1/2 weeks all fixed up! I'm a happy customer and I'd like one more Gaucho, a .357 this time and I would quickly comvert it to a 44 special! 44 Man.
