On the Berettas, the locking block is prone to breakage. I don't know if this is true of the Tauruses, but this is something that carried over from the Walther P38 which is is based on. I had a Walther P38, and I had four parts fail - the extractor, the locking block, the firing pin, and the loaded chamber indicator. I traded the Walther for a CZ-75 which my daughter now has.
Here is what Massad Ayoob said about the PT92/99:
“We see a lot of Taurus pistols at Lethal Force Institute. The PT-92 through PT-100 models in 9mm and .40 S&W come in, shoot several hundred rounds, hand leave without a malfunction or a breakage. Acuuracy is comparable to the Beretta, but cost is hundreds of dollars less. Finish may not be quite so nice, nor double-action pull quite so smooth, but these guns are definitely good values.”
