Here's a rundownofmy experience with the model 120 and model 1300 Winchesters.

They are a nice introductory shotgun. I have had great luck with the accuracy of the smoothbore slug barrels, especially with winchester
super -X slugs. My model 120 is the most accurate (and cheapest ) shotgun I own.
I have spent more $ repairing it and replacing parts than I initially spent on it, which tells you I like it. In general, I feel they are very barrel heavy. The forend tends to be pretty sloppy. The wood quality on mine is very basic. The barrels seemed to rust a lot easier than other shotguns I own. Add to this that they are no longer being made.

If you could get a good price on one and use it for its intended purpose as a well functioning, accurate, beater shotgun, then I wouldn't hesitate. If you like the remingtons, you should be able to get an 870 for about the same price. I myself never liked the fit of the 870, and thus have never owned one. I am primarily an Ithaca man, but bought the winchester 120 (my first shotgun), and inherited the 1300. Both have the youth stocks which I actually like when up in a deer stand.
