Actually it isn't all that surprising to me.

I guess maybe because I read about it a while back. The P320 was basically a redesign of the P250 and it seems in the design process Sig wanted to retain as many of the same parts between models. The P250 was a heavier and hammered version that could go off if dropped on it's butt - i.e. firing from inertia. The P320 is hammerless with a fully preset striker instead. A big issue is in the P320 there is no separate lever like found on nearly every other striker fired gun. That piece in a gun is an inertial drop safety. In other words it stops the trigger from pulling itself under inertia when the gun is dropped.

It is also important to note the striker is under full spring pressure in the P320 (and honestly many if not most similar handguns). This basically means it is fully cocked and requires less force to pull the trigger. Throw in the fact that in the rush to produce the P320 and retain parts between the two, they didn't bother to replace the trigger until issues started popping up and only then under a "voluntary" upgrade program and I don't think they were in the NEW guns until 2019. The new trigger is much lighter weight to help prevent this problem of firing from inertia. These add up to a series of design flaws IMHO.

There is a second issue that compounded the trigger problem. The striker safety lever and sear springs could become entangled and bound up leaving the striker safety disengaged and the sear not fully engaged. This could potentially cause the safety to fail and the pistol to fire unintentionally when subjected to impacts.

Sue the manufacture for making a defective product.

They have been and losing for some reason. I have not looked into why but I suspect it has to do with the silent recall on them.
