Welcome aboard!
Not even remotely in the area, but theres a 590a1 model 51663 (20" w/GRS) hangin on the wall here in Nashville at my local shop. I'm sure they'd ship to your local FFL. We've got a great group of folks here on Mossberg Owners and the atmosphere is very laid back. The only thing we like better than discussing each other's guns is lookin at 'em, so be sure to post pics of your any firearms you own in the various sub-forums. You'll find that we're into a lot more than just Mossberg around here. Let us know if you have any questions.
Enjoy the site!
