Congrats, sounds like you found the problem. In the unlikely event that it continues to act up (and for the benefit of other members), since it costs probably more than $60 to send the gun to Taurus (and you have to deal with their often lousy customer service), you are nearly always better off to pay a local gunsmith $50 to $75 to fix problems with a Taurus.
I hear you on your next gun being a S&W. I am partial to them myself, but a working Taurus should also provide years of trouble free service. I had a 6" Taurus 66 I should have never sold, and I'm the happy owner of a cool blued 3" Model 431 .44 Special. Hopefully once this glitch is corrected you'll get lots of good use out of it.
