Model 10-7

[GoneHunting]

I found a model 10-7 in a local gun store.  The gun in new with box.  I know it hasn't been produce for several years but I know this gun is new.  I know that the -7 is a change but what change is it.  The dealer wants 350 plus tax.  Is this gun worth that much or should I wait and find something different. I already have a model 13 so I really don't need the 10.  I just knew it was no longer in production and found one new with box.  Info will be greatly appreciated.
