1911 10 round magazine

Chip McCormick Power Mags and Wilsons both work great for me.

+1 on that. I had one of each and they worked fine. Quit using them as they were just too big for me to index them properly during reloading. I used them as the initial mag in the gun. Then I would go to an 8 rounder. They fed fine though.

I use CMC 10rd Power Mags; they work great in my single stack 1911's.

SCMA-1

Likewise. I have two of them and they feed reliably into my RIA.
