Sellier & Bellot 180GR FMJ and PMC 170GR JHP
With .45acp the Wilson Combat 47D mags worked WONDERS over the stock Springfield mags that came with my TRP. If Wilson makes a 10mm 1911 mag... I could only suggest trying out one of their mags and seeing if that might help remedy some of the issues your having. I just picked up a TRP 10mm yesterday and will see if I have similar issues.
