Realistically, any mag that works will do for banging plates. For duty or carry, you want the best mags you can get.
I was carrying a 1911 long before today's plethora of mags were available. CMC Shooting Stars and Wilsons were some of the first good mags you could buy and they worked fine. I used 7 round Metalforms with the round follower for awhile and had excellent service from them. I sent them on to one of my sons with an early Springfield and he's had some trouble with them. I had that pistol here for a year while he was in Afghanistan and it ran fine. I read elsewhere that some Metalforms had faulty springs in them that required replacement; so I wonder if mine were from that batch.
I think Wilsons are OK but I've not used them much. I had such good service from CMC Powermags and the later, 8 round 'Classics' that I never saw a need to switch. I'll eventually order a Tripp or two just to satisfy my curiosity about them.
