I have a 320C that I purchased in 2018 and have shot less than 100 rounds out of. I tried to sell it recently and was offered by two gun stores, less than $200. MSRP was around $500. Very annoyed with Sig over this. Their statements have been no help either, talk about Streisand effect.
That's a normal price drop for most modern plastic guns when trying to sell them to a store. They will offer $200 and sell it for $350 next to the brand new ones at $475.
They are in a peculiar logical pickle: admit the gun is defective and lose all their current lawsuits plus many more that will dogpile on. Plus take a devastating hit to future sales.
Or deny it, saving face and relying on FUD that the discharges (several were caught on video ) were random or somehow the fault of the owners. Sig were even using some anti-anti-gun arguments (the same retorts that 2A people use against no-gun advocates) against their own customers! Saying they weren't being responsible or something along that line. It's a terrible situation for everyone involved.
