The Beretta Model 92, 92S, 92SB & 92F had the issue.
The Beretta Model 92FS was suppose to correct the issue.
But, I hear it's still somewhat of an issue and the correction was just to ensure it doesn't become a catastrophic failure.
Could be reason why Beretta developed the 8000 series and PX4 series as a replacement for the 92 series.
The issue of it failing is very small and you shouldn't worry about it, unless you shot more than 20,000 rounds through your 92.
