The only factory mags I've ever seen are all 10rd, though they're easy to modify to hold 12-13.
Kind of a niche market, so hasn't been a lot of pressure to innovate in that space, especially with the cost and supply issues of 22 in the obummer years.
FWIW I've modified my one mag to hold more than 10, and just use that when I take out the conversion to shoot. That's very odd for me, since I usually stack mags to at least double digits for every platform I own.
