The LGS in my area with the best selection and usually more than one of each gun is a pawn shop. It's busy every day. I usually stop in twice a week. Every time I'm there someone is buying something.
The other two shops are not very busy. One has empty cabinets and a few consignment pieces, I don't know how they stay open. The second is a LE supplier and that's his emphasis, the rest of us are just icing on the cake if we buy. I shoot on this shops range twice a week. I can't remember seeing anyone buying anything for a long time.
