Call S&W directly and order them. They will tell you that they are on backorder and cannot give you an ETA.
I ordered two 25rd mags by calling S&W directly on 4/10/13. Just got home from work and to my surprise there were two 25rd mags waiting for me in my mailbox. 19 day turnaround for mags that were on "death backorder". Not bad. Not bad at all!
What's odd is I never received an order confirmation or shipping notification from S&W, like I was told I would. I'm not even sure if my credit card was ever charged. (Edit to add: Just double checked and I was billed on 4/24/13)
Another oddity... One of the mags didn't come with a load assist button. I double checked and they're both 25rd mags. Both have the red followers and neither of them stop after loading only 10 rounds into them.
Call Smith & Wesson:
