Some Taurus guns from Brazil get good reviews today but historically Taurus guns have been junk. My family visited a gun enthusiast we know in Arizona and went to the shooting range and the people next to them were struggling with a Taurus that was jamming.
The reports I have seen (for example, from the AP) say it was a Bersa (a company based in Argentina), not a Taurus.
Wow, the video... that is quite a bit of good luck and/or poor weapon maintenance. And this not long at all after Shinzo Abe... very disturbing, hopefully not the beginning of a trend.
