Sorry, but your story seems to be consistent with many that I've heard over the past few years. Taurus CS is not good, despite what they claim. Their lifetime warranty is worthless because you can never get your gun serviced and returned in a timely manner.
I've had a bad experience with them and also won't buy another Taurus unless I can get it for next to nothing so that I can throw it away if it fails. And I would likely only ever use one for a range gun, not an EDC.
