what do you guys recommend for a plus 2 mag tube extension for an 1100 12ga?
Vang.
I look at Hans Vang as a Mark Larue for shotguns. His mag tubes (like his followers and safeties) are proprietary and top shelf.
As if Pat needs a +1, but …what he said:D
The Remington or Scattergun…I mean Wilson +2s aren’t bad either. I have used all three with out issues.
