I have a Taurus PT-99F.
As limaxray stated, the Taurus has a frame mounted safety. The Beretta has a "decocker" on the slide. Later Taurus (Tauri???) The PT-92AF and PT-99AF, have a safety that is Up for safe, horizontal for fire, and you press down against a spring to decock.
The barrel and locking block, recoil spring, and many other parts are interchangable.
The mags are almost interchangable. The mag catch hole on the Taurus mags is larger. The Beretta will accept and work with Taurus mags, but not vice-versa.
I cannot tell, from about 15 years of use, that the Taurus is of any lesser quality than the Beretta. Mine has worked well for years, gives good accuracy, yes, about 2" at 25 yds.
My only complaint was that the beautiful uncheckered Goncalo Alvez wood (aka "South American Walnut") grips, with a little sweat and gun oil on your hands, as slippery as a greasy ice cube. I put on some Pacmayr's and that fixed that problem.
Usual ammo is Winchester Silvertips 115 gr JHP or Federal 115 gr JHP.
