RE: Which 20ga. pump would you choose?
No question the 1300 would come home. They are a very rugged and reliable shotgun that will last for many years to come.
What I really like about the 1300 is the fact that it uses a rotating bolt head with four individual locking lugs that lock up inside the barrel instead of a single locking block that locks into the barrel extension like on the 870.
As far as the nova goes I am not a plastic shotgun fan.
