I "suspect" both the magazines are made by another company
for S&W.

So, it then becomes an issue of priorities.

I would guess that the largest amount of demand is for the
25 rounders which only very recently started showing up.

If I had to guess, I'd think they are coming.

Personally, I am NOT in a state that requires the ONLY 10rd
capacity. BUT, I do want a couple myself... On my AR's I use
the small mags to simply act as a block to debris while those
rifles rest in their bags.

Once they are available >again< I plan to hold off getting a
couple until those in urgent need can get what they need.
