I've got a 744. I put on a pachmayr presentation grip and it feels great. I had lots of trouble finding a holster as well, but I had a nice form fit one made by the triple K company through this place: http://www.cowboyneeds.com/TK_Holsters.html
It had to be made at the factory and took several weeks but at least I got one. You won't find one in stock in any store.
I just looked at this site and the gun is not listed in there any more, but you may can call them and see if they'll still special order you one. ... or contact the triple K company directly. Other than that, you'll likely have to go with a custom made one or a generic one... very expensive or very crappy.
