Yes, the real sig that was adopted by the US army had a 1911 style safety. But the commercial model without the safety was subsequently adopted by many american police forces, this is when the first incident happened, but still wasn't acknowledged by sig until 6 months later. If you drop a stock sig p320 on the back end of the slide, the trigger will actually get pulled by gravety and the gun will go off. Some people even got their p320s to go off by hitting the back of the slide with a rubber mallet. The competition and ninjafied models had lighter triggers (the trigger is physically lighter) and weren't plagued with this issue.
Essentially now, sig hasn't recalled the pistol despite having several court cases involving police officers dropping their guns (while in holsters) and shooting themselves. They have at least offered to fix it for those who want to through their RMA system. Sig still however is denying that it's a major issue that necessitates a recall. It does take a very specific angle to drop the gun and have it set off, but there's no reason it should go off when dropped at all.
Anyway, this gun looks cool and I do like the p320 despite sig sucking currently (the new sign 365 compact 9mm has some major striker drag issues that would break the tip off your striker within 400 rounds. Sig quietly changed the striker design even though they haven't acknowledged the issue and the "new" version of the gun still drags the striker all the way across the primer, practically pinching it over brass, so who knows if it will still destroy strikers) so hopefully the gun will be cool.
