Doubt it very highly.

- A manufacturer isn't going to do a special just for Walmart of "lesser quality" guns.

- Also not going to want to jeopordize future sales and reputation making "lesser quality" models.

Dealers will pronounce up and down evil doing of walmart and the substandard quality of the guns sold there as the reason for thier low prices. Walmart can just buy in such huge quantities, they're pretty much thier own private distributor so they pay much less. That's how they can sell some models at lower than what the normal FFL dealer can buy them at wholesale.
