I was going to jokingly post that (about buying it from him) as it is surely a nice gun I'd love to have.
As for the 'two-sear' thing, that WAS a joke (as the gun was ACTING like it had a second sear cut near full-cock) and I was commiserating as to how it would have been nice if someone (an 'expert') had posted here to reassure him that everything was fine and normal. But it's not fine and normal, unfortunately. I hope S&W or an authorized S&W service center gets it all sorted out and he can pop back on here and let us know what the issue REALLY was.
The temptation would be to pop off the side plate and 'look', but the minute you take the thing apart, then the manufacturer could (rightly so) claim the gun had been tampered with and then they might deny any repair claim. OP is doing the right thing getting it to a gunsmith/repair center for a 'look-see'. Thankfully the gun shoots great, so if they get the 'two-full-cocking-points' issue sorted out, he'll be good to go.
