Trista, there is no current eta in the current high demand, low supply market. Just place it on both your Wish and Notify Me Lists and Buds will send you an email notification if/when available. I would check on large gun and accessory sites like (6)un (8)roker as discontinued and hard to find firearms and accessories show up for sale by private individuals and small shops. Just replace (6) & (8) with G & B.

Trista, available here >>>>>> dowdlesports.com/Walther-PPKS-22LR-10rd-Mag_p_16923.html

Trista, they are available here currently : dowdlesports.com/Walther-PPKS-22LR-10rd-Mag_p_16923.html

Buds doesn't receive etas on when or if items will be back in stock your best bet is to hit the notify me when available button to receive an email when they come back in stock.
If you need them now the 10rd magazines are available here
