I've heard the stories both ways about Taurus and have owned a few and have never had an issue. A few years ago I traded into a PT92 that needed fixed. I called the folks in Fla. and told them and within days I had the parts in hand no charge. Conversely I bought a series 80 Colt 1911 brand new and experienced nothing but problems with failure to feed and failure to eject problems.
I worked on it myself and had gunsmiths work on it along with Colt. It never was a dependable weapon. I ended up trading it for a Ruger mini 30.I have both Springfield and Kimber 1911's and they run perfectly.
The Taurus 9 mm has swallowed probably 2k rounds with out a hiccup so I think the answer is like many things mass produced sometimes **** happens. If you're happy with the performance then run with it.
I just bought a P238 Sig and have a couple hundred rounds through it and so far so good.
