It’d be nice if they started selling firearms in CA again. IIRC, they stopped because of multiple instances of Walmart not following legal requirements to the letter during the purchasing process, and the CA AG came down on them. WM decided to stop firearm sales altogether, perhaps as part of a deal with the AG office?
Anyhow, many still sell ammo. If they ever sold handguns in CA, it must have been a long time ago.
