If your near Plainfield, Ill. chech out The Gunshop and Megasports. I-55 and RT 30, go west into Plainfield. The Gunshop is in a strip mall on the left and Megasports is just up the road on the left.
The Gunshop is smaller but had some 03 springfields, Lc Smiths and a Parker Trojan.

Megasports has a huge selection of modern things. There is also a Gander Mountain too.
