welcome to FRF!
i believe the 19EX is a hybrid and there's a Wildwood sub-forum in the Expandable/Hybrid section here.
it's not very active, since not many Wildwood hybrids were sold, compared to the other FR hybrid lines.
but most things unique to hybrids, are things they all have, no matter what brand it is.
so, if you need info on hybrids or ideas for mods, be sure to check it out.
