Slug barrel for the impact mk 2 .35 cal?

[Oldandintheway]

When I bought my FX MK 2 .35 cal two years ago, I was told that they were working on on a slug barrel. 

Has anybody heard anything about the .35 cal slug barrel? Does it exist? What are they waiting for?

I've put a 700mm .30 barrel on it. I've been waiting for too long.
