If I remember correctly, Winchester made a marine defender 1300 series also.
I'll take your word for that. I never researched it. :)

More useless info: I did make a couple of other simple mods several years ago.

A slight bevel around the loading port to eliminate the sharp edges, and make loading a tiny bit easier.

And some decoration on the grip - Marinecote->Marine Corps. :lol:

Not from the factory, they're all cyl bore. You'd have to thread the barrel for a screw in choke. That said, if you shoot something like a Brenneke slug or Federal Flight Control Buckshot (which is what I use), you really don't need a choke. :)

BTW, the early models with the shiny Marinecote finish, are sometimes hawked as "stainless steel" in the used gun market for exorbitant prices. They aren't. Mossberg never made a stainless version, but some folks do get suckered in.

I tend to believe, like an 870, she'll deliver a pretty strong kick when firing slugs or buckshot

You betcha. Push/pull is required to avoid a dislocated shoulder with 546grn (1.25 oz) Brenneke Green Lightning at 1476 fps. :shock: And that's not their big boy (Magnum Crush).
