*****Gone. Sounds like the price was right for the people who bought these few that were available. It's sort of like ammo was a couple of months back where everything was out of stock and people just went nuts and bought everything they could immediately. Ammo is coming back as are prices on popular calibers like 9mm, .40, and .45acp.
Eventually, M&P mags will come back with several thousand units getting dumped on the market. Expect to see this happen on or about Oct 2 of this year...
