These are great magazines, used them for years for problemsIf it's a 45 ACP use the Chip McCormick mags, they're great and not very expensive.
I use Act Mags in my RIA and they run smooth and never had an issue with them. I think they also go by the name of Novak, but don't quote me on that one.
Chip McCormick PowerMag+ fan here
Wilson 47d's are great too
