Just curious if anyone has had any experiences with a Winchester 20g slug gun. I have an upland special and may purchase a extra barrel. I would be using the iron sights. Are they o.k.? Is it worth the investment, or should I put in a little more money into it and just get a knew gun. If so, any suggestions on what to get. I kinda like the older Remington 1100's. Just a note, the gun would be for a 13 year old to use.
