i learned to fix my own years ago when I didn't have the money to pay for repairs. My accumulated info was almost exclusively Smith & Wesson, since that was (and still is) my favorite brand. But over the years, as so many guns on my "buy it" list were priced out of my league, I've picked up several Taurus firearms to fill in the "blanks" in my accumulation. My experience with S&Ws has carried over nicely to my Taurus and Rossi revolvers. For instance, Rossi had a "big deal" recall of Model 461, 462, and (I think) 451 .38 and .357 short-barrel revolvers. They weren't very forthcoming about what the problem was, only that it involved the possibility of firing if the gun was dropped. Since I had looked long and far to find a stainless 462, I was not about to return it to Taurus/Rossi, only to get an inferior replacement. So I went "under the hood" and discovered that the apparent reason for recall was a defective hammer block, the skinny flag-looking part that doesn't drop down out of the way until the trigger is pulled. Mine was twisted and didn't slide; everything else functioned as it should. Well, wouldn't you know it, the corresponding S&W part fit and functioned properly! I saved my gun from an unknown fate!!!
Well, you get the idea: you are much, much better off diving in there and learning what makes it tick. worst case is the gun can't be fixed, and you've found that out in a lot less time than sending it to Taurus. And good replacement parts are available out there from places like Jack First or USA Guns and Gear. You just have to look for them. In some cases, you may be able to straighten out a bent part or bend one that's supposed to be bent and get your gun back in service.
Think of it as an exercise in developing survival skills. If the worst possible disruption of this country ever occurs, you aren't going to be sending your gun in to anybody. You either fix it or throw it away. Learn how to do it yourself and be less dependent on unreliable sources for help!
