The official response was that they would have to double the amount of optics in the gun... and they would love one that would work in both... but they would have had to increase the price considerably.
And after all that... they didn't think to many would use it on both... so they will do another product (if they get enough responses).
So if you want one, email them and ask if they are selling one... and after they say no, ask if they are taking preorders yet... this usually gets companies to start looking at actually delivering a product.
