Just buy Wilson Combat mags and be done with it; they make the best 1911 magazines,
I think it was Last Man Standing that made me want to buy some extra mags. I bought 8, 8 round 47Ds and they all had problems in my Colt MK IV Series 80. Usually the next to last round double fed. Wilson was very nice about it and sent me 8 extra power springs for them. This fixed most of them but there are still a couple problematic ones.
I have an old 8 round Wilson Rogers mag that is flawless still.
I have an old 8 round Mag-Pac Magazine that is flawless also.
The original Colt 7 round Mag that came with my gun has never given me an issue and still carries the original spring. It gets shot less than the other Mags though.
