Ron, these were Hornady .45 sabots for .355-357 bullets. Although they say you can use them with 9mm (.355), I'd guess the results would be even worse. I'll switch to .40s if necessary, but I'll probably try MMP sabots before I make that change.

Corey, don't believe everything you hear about rates of twist. I think there's a lot more SWAG and voodoo on that subject than tested knowledge.
