That's like asking which Tires you like?
Here's my recommendations:

Tripp Cobra Mags. Not the cheapest, but the best:

I will also recommend to you that you stay away from 8 round .45 magazines as they do not work well in all 1911's.
The Tripp 7 round mags for both the Govt./Commander and also 7 rounders for the Officers/Compacts work extremely well in most 1911's.

2nd best in my opinion is Wilson Combat, but I sold the 8 rounders I had in favor of the 7 round Tripp Cobra's.
