I own both; I have specimens of each that are about 15 years and have seen hard use and thousands of rounds.
I read that both pistols are weak in the locking lug area
Actually, it's the Beretta 92 that had a history of locking block and slide breakage. Beretta has long since addressed both issues, although the locking blocks will still eventually go -- but we're typically talking upwards of 25,000 rounds or over -- which in all likelihood, only military pistols will ever see.
[Taurus] Blued finish isn't very durable
Well, the blue finish on my purchased-in-1991 PT-92 has held up well, and the high polish on the slide still looks great. This PT-92 has well over 20,000 rounds through it and has never, ever malfunctioned.
As far as accuracy goes, my old PT-92 is actually more accurate than one of my 92s, and as accurate as another. My newest Inox 92FS will, however, outshoot the PT-92.
The PT-92 mags can be made to fit the 92FS (widen the cut-out slots on the front of the mag) but the floorplates will still be slightly too small due to the recurve on the bottom frontstrap of the 92FS. Not recommended; use the magazines manufactured for your pistol.
As one who prefers the 1911 Gov't Model above all others, I do prefer the Taurus frame-mounted safety system. I think the PT-92 is an entirely worthy pistol in its own right, and regard it as the equal of the 92FS (which has been my duty issue weapon since 1994).
