I have a 669 i got used. Its broke, had my gunsmith look at it and couldn't fix it. He did a strip and said it looked like a previous owner had tried to use a screwdriver to strip it and gouged a piece which is worrisome seing taurus says it doesn't cover abuse and may just use that as an excuse to tell me to screw off (there rep is very bad.) The problem is its not locking up and cylinder comes out on its own. Im wondering what to expect sending this thing in. And what does taurus do if they can't fi it, credit or something?
