The Sig Sauer P320 is a striker-fired pistol (different from a hammer-fired pistol). The typical mechanism of a striker-fired pistol is that, upon loading, the striker is partially cocked. Any subsequent shot will result in a reload and a reset of the striker. This is done in order for the trigger pull to require less force than for a full double-action-type pull. This feature is common among striker-fired pistols, including Glocks.
It seems that the "foolproof" mechanism is subject to an as-yet-unknown failure mode, and there should be a thorough forensic disassembly and analysis of the involved pistols. Frankly, I think the only convincing rectifications of this problem would be to (a) add a manual safety to the mechanism, (b) revert to a double-action trigger, or (c) both the previous. I think also that any such design change should be accompanied by a withdrawal of the P320 model from sales.
Sig Sauer has a brand reputation for quality and durability, by which qualities it was chosen as the new service sidearm. I am sure they would want to correct this horrendous problem swiftly---but their lawyers seem interested in waving away the evidence with court findings. Not a good face to put before the shooting public.
