Which ones seem to be the best and which ones (if any) should be avoided?

[Navy joe]

Wilson the best, I prefer steel basepads. Chip McCormick pretty good, the ten rounders are nice until the plastic gets beat up and you over-insert one. Wilson 10's are the best. Shooting Star pretty good. Factory? Maybe.

Avoid? Anything cheap at a gunshow. Many old USGI mags run great, but it's hard to pick them out of a line-up.

[Mil Novecientos Once]

Many people will suggest Wilson Rogers, others will say Chip McCormick. Others, like I, will say Metalform: 7 round, stainless steel body, round top follower, and welded base.

You should buy at least a a pair from each brand to do your own tests.

Colt horse marked mags have been 100% for me in all calibers I've used including 9mm, 10mm, 40 S&W, 38 Special, Super 38, and 45 ACP.

I'm running a mix of 7- and 8-round Wilson Combats right now in my Kimber, but have used Chip McCormick's in the past, too, with great success. Another brand I'm interested in sampling is Wolff.

I have more Wilson 47Ds than anything else...I must be getting old...I raised this question in a similar fashion awhile back...I have a hogedpodge of 7 and 8 rdrs...I just make sure they run the gun everytime, inspect and maintain...since they all do- I grab whatever's handy and use them. I decided to quit worrying about everything...I never believed in 'buying' skill and targets...I 'm getting really back to simple and redundant...
Just get a good pair of smooth jaw needle nose pliers pliers..."magazine adjusting tool..." I use Lindstroms' for this...

I have 7 & 8 round Wilson mags but I've had the best most consistent performance from the 7 round mags.

As for which ones to stay away from...I have yet to find a 10 round mag that has been 100% reliable ;)

I've had 50/50 experience with metalform horse ("M" on one corner) marked Colt's magazines. Two I played with wouldn't run in any gun I put them in. Another two worked perfectly.

Factory Colt ("c" marked with horse) runs 100%
So do some supposedly imported from Israel. Very, very strong springs. Rust resistant mag bodies and dirt cheap. Older imports have ".45 ACP 7 RDS" on the left side. Newer ones have a Star of David and "J.O. ISRAEL ARMS" on the left side.

I've decided not to keep magazines that don't run. They screw up twice that I can trace to the magazine, I put 'em downrange. I've only had to deal with one mag this way.

The plastic follower on the Wilson Mags wears out too fast.

Other than that Wilsons are good mags.

I prefer McCormick's because they don't have the plastic follower.

I've got a bunch of Chip McCormick Shooting Star mags that mave never let me down. In 8 round blued flavor, they are very affordable also. I've also got a pair of MecGars that seem reliable and well made but not too many rounds through those yet. Mec Gar does make the OEM factory mags for a lot of guns.

I picked up a big stack of cheap 7 round surplus mags from www.aspitactical.com strictly for range use only. These have been completely reliable except for one that never worked from day one.

Mec-Gars (http://www.midsouthshooterssupply.com/deptsearch3x.asp?dept=%47%55%4E%20%43%41%52%45%20%26%20%41%43%43%2E&dept2=%4D%41%47%41%5A%49%4E%45%53&dept3=%43%4F%4C%54%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20) have worked fine in my Springfield.

I think this question is worded wrong. The question should be, "What 1911 type magazines should I avoid?" To that I would simply add, avoid gun show bargains. If you must buy them, relegate them to the range only.

[CWL]

ditto on the Wilsons and Chip McCormack/Shooting Stars.

I'd stay away from ALL 10-rounders, but that's just my opinion.

Will be trying some of Virgil Tripp's CobraMags soon. Reputationwise, these are supposed to be great.

I've found that Metalform's "low capacity" magazines (7 round in .45, 8 round in 10mm) work well. Factory Colt mags work well. The best 8-round .45 magazines I've found are Wilsons, but the 1 CMC PowerMag I tried worked well too. The best 10mm magazines I've found are the Colt or Metalform 8-rounders with rounded metal followers. I'm going to try out some Mec-Gars soon too, since I've got a new 10mm that needs plenty of mags. :D

Two words, Wilson Rogers.
