I can't speak for the modern M9, which is based on the modern PT-92/99 series. But I've got an old Taurus PT-99, which was made on Baretta equipment in Brazil. It's the old-style PT-99 with a 1911 style, frame mounted safety. It's been incredibly reliable, and for 3 years I used it for USPSA shooting, putting about 35,000 rounds through it in those 3 years. During those 3 years I only had 2 problems. The first was after loading up some "interesting" rounds with IMI 169gr FMJBT bullets... Which I later learned to be +P+ SMG rounds. After about 9 rounds the weapon refused to cycle. It has broken one of the two locking lugs, jamming the weapon closed. It was easy to clear, but I was impressed with the strength of the gun, even with the open slide. The second problem was during a match where I noticed something had changed, but I couldn't quite put my finger on the problem: After the stage I found that the rear sight had fallen off the gun.
In both cases, Taurus fixed the problems with no questions asked.

I had one of the early model 92 Berettas. It not only had the frame mounted safety, the mag release was near the bottom of the grip.
I had bought some very cheap ammo. It was described as sub machine gun ammo but not over pressure. In other words safe to fire in pistols.
One day my Nephew and I decided to shoot up what was left of it. We brought two guns, a Browning Hi-Power and that Beretta.
Now that Browning had never had any problems at all, no jams, failure to fire or anything else. Unfortunately about every other round of that 9mm, the gun did not fire. It would always fire on the second try. The Beretta never failed a single time.
Nothing really wrong with the Browning as that was not the ammo it was designed for but I did appreciate that the Beretta did fire with it 100%.
