I've owned 3 Taurus semiauto pistols and have had zero issues with them. Currently I still own and carry one of their semi's, a PT 740Slim and have no issues so far.
In my experience, their quality is good. Not the best, but you are also not paying top dollar for their firearms. I've had worse experiences with some Keltec's and even Glock's
From what everyone is saying, their QC and CS are the main downfalls. Thankfully I have never had to put their CS and Warranty to the test. I don't know if you can call me one of the "lucky ones". But 3 of their pistols I have owned has not given me any problems.
Of course YMMV.
