No it's definitely not tolerance stacking problems on critical safety components designed in a way that doesn't positively stop the striker if released unintentionally, and those parts that were sourced from dirt floor "factory", barefoot jeets are definitely in tolerance.
The handgun is perfect, their own quality department inspected those suspect guns and said everyone was making stuff up.
Really the only firearm I can think of where saying "guns kill people" would be correct.
They outsourced the parts fabrication to India.
On a side note the current owner of Sig is a kike.
