FNS 9 Trigger

Near as most of us can tell, it's the trigger safety. Push the trigger forward too far and it catches on the frame.

Incidentally, I have a 2012 model as well, and I can only partially replicate the "lock up" as some seem to like to call it. To generate the issue by impacting the barrel you have to use far more force than anyone in their right mind would EVER put on the firearm (ball peen hammer at full swing, anyone?) at which point it is remotely possible to jar the FGC and cause the trigger to come forward and lock against the frame. Mine can easily be powered through by manipulating the slide, or the other option that takes even less effort is placing your index finger behind the trigger and gently pulling with your middle finger until the trigger disengages from the frame.

What was the fix that FN did for this?

Nothing. There have been a few instances where FN has warrantied for this due to it being exacerbated by the odd sub-par FCG, but otherwise it's a non-issue. Newer models don't seem to do it as much so something was re-engineered ever so slightly at one point, but it's considered an annoyance, not a problem as it is a rare occurance and can be "powered through" by manipulating the slide. In reality, it isn't any more or less dangerous (or any different, really) than getting a round with a bad primer.
