Looked around and couldn't find a thread about this made yet. No idea when it's coming but it looks like Sig has developed an enclosed RDS specifically for that goofy footprint on the M17s and M18s. I'm going to guess it should work with anything using a DPP footprint too?

I was going to purchase an ACRO but this honestly gives me some pause. I'd much rather have a direct mounted dot if I can get one enclosed. I do wonder how well a dot that's marketed for a specific gun will fare commercially, but I think it's clear this thing was made with .gov package deals in mind.
