Don't know if this is worth anything. About a week before the COVID lockdown and subsequent panic, a buddy of mine tried offloading his 1.0 version. The LGS said they couldn't give him much for it, because everyone wanted the 2.0 version and said they had one in the case that had been sitting for three months.
He got what he could for it. I'm sure a week later it wouldn't have mattered much.
I ran into the same issue with my Ruger LC9. Absolutely hated that trigger, so I upgraded it and a month later the LC9s came out. There were zero differences between my upgraded trigger and the new model, but mine was worth zilch. Perception matters, so I'd say either buy the 1.0 super cheap, or go with the 2.0.
The problem I see with some lines of guns is their constant state of flux. i'm sure there will be a 3.0 sometime soon too. They aren't like the timeless 1911 of CZ75 or others. Glock changes the slightest things and sales pick back up. Sig offers a new finish, chargers $300 more and sales pick back up. With some, if they aren't changing, they aren't selling, so change they will. Doesn't mean the previous one was flawed, but may lead to that in respects to perception. That may be worth something or not.
