I don't want to hijack this thread, only approach the question from a different angle.
Objectively, no fan boy crap, what mags wouldn't you use. Again, give a solid reason, not because of looks or because "everyone knows Tripp is the best."
I've never been a true high-volume shooter, but I for few years averaged about 5,000 rounds per year through 1911's. I experimented with various mags, because I wanted "the best." I tried a bunch of different brands of mags--Kimber, Wilson, Chip Mc, Tripp, Metalform, Mec Gar and another that I can't recall right now.
In a discussion like this, one of the problems that we are up against, collectively, is that we likely all have different generations of magazines from the same manufacturer. That makes it difficult to compare success and failure rates. Manufacturers don't announce when they are changing something on their mags. So if they go with a different spring, and that spring causes problems in the long run that didn't show up in testing, they change it again. So version 1.0 might have been fine, version 2.0 a bust, and version 3.0 a huge improvement over 2.0. That leaves all of us to argue about how good that mag is/isn't when we don't have the same mag even though they are the same model. Couple that with the fact that those 3 versions might work better in some model guns and worse in others. Getting a consistent and accurate assessment of the quality of the mag is difficult--especially when their are multiple models of magazines from a dozen manufacturers out there and a plethora of different 1911 guns.
Another problem is the "tweaking" that people do to their mags to "improve" them. These guys are creating sub-versions of all the mags that already exist and then broadcasting how good or bad a particular mag is after it's been altered. The problem compounds even further when those altered mags change hands and the buyer doesn't know they aren't original. So the buyer thinks that Brand X is awesome and is sorely disappointed when he buys 6 more that don't run as well.
In my now outdated experience, I found 2 magazines that were 100% consistent for me: Tripp Research 8 rounders and Kimber's KimPro Tac Mags. I know it's cool to hate on Kimber, especially their mags, but I tried two that worked great. I bought another 5 or 6 from Botach for $20 ea, shipped. They came with two different size pads, which was cool, but more importantly, all the mags functioned 100%. Same with the Tripps.
Magazines are not crazy expensive. Nobody likes to spend money on them, but we can all afford to buy any mags we want. The point is: Since we can afford whatever it takes, we all want mags that work and will go buy what works. For me, I have only Tripps and those Kimber mags. When I say they have performed with 100% reliability, I mean 100%.
I have had feeding issues with 2 different Wilsons. I had to change followers on the Chip Mc's to get them to feed reliably. Metalforms were actually pretty good--I can't recall why I parted ways with them--not enough cool factor for a guy just starting out with handguns? Who knows.
So to (finally) answer the question at the top of my post, is there any brand I WON'T use? No. I now assess mags like I assess men--one at a time. There is not a reliable way to evaluate an entire brand. My advice is this: Go buy some mags, any mags. If they work keep them; if they don't work, sell them. Eventually you'll have a collection of mags that work 100% in your gun(s). I know that answer is not a magic bullet, so to speak, but I think it's an accurate answer without any "fanboy crap."
Good luck to us all!
