They are going to take it up the....
"Il bacio della morte" A.K.A. the kiss of death.
Law Enforcement and Military sales are pittance compared to civilian sales, we all know that. But they do have some influence on what people buy and even more on what people do not buy if safety is an issues, right or wrong.
It is my belief that the safety issue is related to some design clash between the gun itself and retention holsters. Sort of like binary explosives: individually they are perfectly safe, but when combined, boom will follow.
SIG took an approach of “fuck you, it ain’t us. It is your problem” rather than go “Hey, let’s figure out why this is happening and let’s fix it together.” Investment on good will could have resulted in increased sales, just like Glock did when they had issues of their own back when they got started, but they chose misguided pride.
And they are going to lose a lot.
Good news however: I figure in a year or sooner, we will have a glut of P320s at deeply discounted prices at Gun Shows.
"It is my belief that the safety issue is related to some design clash between the gun itself and retention holsters."
Nope.

48-minute video, but worth the time if you have it.
TL;DR: The FBI's Ballistic Research Facility (BRF) tested one of the Michigan State Police P320s that "fired uncommanded", which they received untouched in its duty holster after it went off -- in which multiple witnesses to the event state the officer in question had his hands at chest level and was holding his keys -- did a pretty thorough check of all the internals, and ran multiple tests against it and two new, unfired MSP pistols. They found several problems, culminating in the conclusion that a law enforcement officer's normal duty activities (running, jumping, climbing, fighting, pressing the holstered gun against a wall or side of a vehicle, etc.) cause enough movement within the duty holster to render the internal safeties inoperable.
My non-certified-engineer observation: It's too early to tell if it's a flawed design or poor manufacturing tolerances or just bad quality control, but it doesn't matter; those tests run by the FBI do not look good.
I'm sure this memo ain't good news for SIG. It seems that the mismatch of SIG P320, WML attached, holster for such gun + light and loose clothing or small fingers grabbing has contributed quite a bit to the reports of "it went off all by itself".
Maybe a case of "I gotta keep taking the poison, 'cause it cures my disease."?
