Mossberg questions: barrel lengths and sights

[NoirFan]

Hello,

I posted an earlier inquiry here: http://www.thehighroad.org/showthread.php?t=402992&highlight=chicago but I have since done some research and refined my list of requirements for a defensive shotgun. Now, what I am looking for is a:

Mossberg
18.5" non-heavy barrel
Ghost ring sights
Extended magazine, flush with barrel
Bantam stock

The closest one I found is the 590A1 with 18.5" barrel, but I don't like the heavy military barrel. Is there an option I am missing?

Also, as I understand it the Bantam stock can be bought separately and added to any 500/590/590A1, correct?

I think you'll have to compromise on weight or barrel or magazine tube length. The lighter 590 barrel only comes in 20". The 500 with an extended magazine only comes in 20".
