It's hard to tell what people are talking about when they talk about problems with the P320. The documents in question here deal with, among other things, the drop safety problem rather than uncommanded discharges you're talking about. If we're talking about the drop safety issue, it does make sense to ask why they didn't issue a recall instead of their not-a-recall "voluntary upgrade."
Thanks for the correction, Sig did call it a voluntary upgrade, not a recall. The do have other actual recalls, like on the Sig Cross rifle, so they are willing to do it when there is an issue that calls for it.
