Are there any?  Looking for something similar to the 10 round 45 ACP 1911 mags.

Tripp Cobra mags are the only ones I know of.
Available from Dawson, https://dawsonprecision.com/magazine-for-10mm-10-rd-by-tripp-research/
or directly from Tripp.  https://www.trippresearchinc.com/10r-10mm-rg/

Hope this helps.

Exactly what I was looking for but couldn't find.  Two are now inbound.  Thanks.
