WalMart gun depts in CA have been effectively closed for several years because of the previously mentioned BATF-related issue. If I recall correctly, the problem was not a violation of Federal regs, but rather a violation of California regs, which are rather draconian. The state AG's office under Lockyear has just been nuts about guns over the last eight years or so, and I don't expect it will change much under new AG Brown. Even though no WalMart guns in CA, virtually all still sell ammo and other gear, some stores with better selection than others. Two years ago, several WalMart managers told me that they would start selling guns again as soon as some issues were settled. We are still waiting.
