Yep, it's a 1200 according to all the schematics I've downloaded.
Removed the barrel this morning and cleaned the shot tube.
Looks to be unfired. No marks whatsoever on the bolt face.
It's 18.5". How convenient.
And I'll check the pull length and post it later.
I might have given all the money for it ($250), but it's exactly what I was looking for as an inexpensive home defense shotgun.
Ya think I did ok?
