I've owned 5 Taurus gun and have sent two back, both fixed to my satisfaction, and both were issues they probably could have refused to fix. What I have learned though is that you must be very specific about what the problem is. A commemt like 'fix as necessary' or 'this is a P.O.S.' will not get the job done. One of my Gaucho's (my favorite shooting single action) came with a too short front sight. I gave it to my favorite gunsmith to send back and he sent the note 'fix as necessary' as he forgot what the problem was. If I had not called and talked to them while they had the gun, I would have gotten it back in the same condition as everything was working corectly mechanically. As it was they put a new barrel on with the correct height front sight and sent if back to me. I'm happy!
The second Gaucho to go back didn't line up the cylinder holes in the middle of the loading gate. That's a common problem with many single actions I have owned and it's easy enough to fix at home, but since it was under warranty, why not send it in? So it went back and came back with the proper adjustment. They are very willing to fix the problem, but as I said, you must be very specific as to what the problem is. Otherwise they will cycle the action a few times, if it appears ok, send it back, same as my own gunsmith if he doesn't know what it's doing for me. Call them, tell them the problem, send it in with a very specific note, call them again in a couple weeks and remind them what the problem is. You should be able to have good factory service from them, as I did. And just for the info, I have had problems with Rugers, EMF's, Uberti's, and Colt's also. 44 Man
