Hello again! To clarify, the grips will not be backwards compatible due to the fact that we shortened the LOP by 1", which in turn affected the rear of the grip interface. We initially went over this in the thread where Tyler from MKM started to make vertical aftermarket grips for the Gen1
As for timelines and pricing; I won't go into too much depth as there is still a lot in the works but long story short, these things have been a nightmare to redesign from scratch and get to a point where they can be manufactured at a reasonable cost and time. We don't want another 18 month lead time on these when they are re-released. The samples we had at SHOT are still pre-production, so a Q3 timeline (if everything goes to plan and the world figures out it's supply chain issues) is possible, however, may be tricky to hit.
We understand that it's taken a long time and that from the outside it seems like we're sitting on our hands, but I can assure you that these are being pushed as hard as they can! Our biggest struggle has been keeping the fit, finish, feel and quality of the original, but being able to bring it into 2022 (in terms of manufacturability and functionality). We have intentionally not updated a lot of the features, as a lot of those are what you loved about it!
Sorry that I don't have better news and we're just as excited to have them back in the wild as you guys are, but it's still very much in the Design/Engineering phase.
