One store here with a few outlets has another sales model. They don't have a large selection but they do have a large size selection. They research the products offered and stock only the best. Prices are high, but their stuff is good.
They also have a used rifle and shotgun section. All the offerings have been through a (over) qualified gunsmith.
I think many stores run into trouble trying to anticipate customer tastes and fancy then get stuck with a lot of stuff that doesn't move.
This store stocks a limited selection, most of the customers are looking for what they carry. Like I said, mostly high end stuff. I've yet to buy anything from them that isn't top notch quality, lasts and works like advertised. Open since 1908.
