As I said earlier, in the Chip McCormick line-up, just get the regular PowerMag. It is their best mag.

Yes, I was the one that advised you to stay away from 10 round magazines. Just buy the 8 round PowerMag.

Then you were advised poorly. Power mags work great
I never said PowerMags didn't work. I advised against 10 round mags as the OP commented. In the McCormick line-up, their "flagship" mag is the 8 round PowerMag. It is their best mag. Are the McCormick 10 rounders good for 10 rounders, and possibly even the best 10 rounders on the market? You could probably make a strong case for that. However, I suspect if you asked Chip McCormick himself, what is his most reliable mag, he would most likely say the 8 round PowerMag.
As I commented earlier...

The pecking order typically for reliable mags, all things being equal, are 7 round mags (the mag the 1911 was designed for) are the most reliable, then 8 round mags, followed by 10 round mags, and you can find 15 rounders somewhere, but they are really just a novelty (or paperweight) item.
For example (since McCormick doesn't offer a 7 round full size mag), if you asked Bill Wilson to pick the most reliable mag out of his full line-up of reliable mags, my guess is he would probably pick his 47 HD/+P mag (followed by the baseline 47), then he'd pick the ETM 8 rounder (then the 47D), and his least reliable (out of a bunch of reliable mags) would be his 10 rounder. I'm not saying 10 rounder won't work, but I'm convinced they will be the least reliable mag when comparing 7, 8, or 10 round full size mags.
What we have here is a guy that knows very little about the 1911. He is asking for advice to make his 1911 experience as good as possible. The 1911, like most autoloaders, is very mag sensitive. He's determined, from recommendations from THR forum members, he'd like to get mags from Wilson and McCormick. To help make his experience as good as possible, I think we should help him by recommending the best possible mag from those makers to ensure the most reliable operation in his pistol.
From McCormick, that would be the 8 round PowerMag, the best mag in their line-up.
From Wilson, that would be the 47, if 7 rounds is OK, but if you need to have an 8 rounder, the ETM is a better mag than the 47D. You may prefer the 47D for price or other features, but the ETM is Wilson's best 8 rounder.
I suspect neither maker will claim their best mag is their 10 rounder. You may like 10 rounders, but they are not the best/most reliable mag those makers produce.
