Not that my sad attempt at pistol-shooting would reveal. :eek:
Wow! I was considering selling a few guns and buying an Ed Brown Special Forces. However if the gun will only work reliably with one type of 1911 Mag, it is a no-go.
I have seen some 1911s that don't work reliably with one particular brand of magazine, but work fine with several brands. But a 1911 that will only work reliably with one brand? No way, for me, unless that is the only 1911 that you own and the only brand of magazines that you will be buying.
I would wager that the Tripp 8 Round Gen II Cobra Mag would work. Best spring, tube,and follower that I have ever seen in 30 years. I have shot the rest, and recently tested, and continue to test the Cobra Mag. YMMV

From the passage I quoted Jmart said that he tried "new McCormick Powermag mag tubes fitted with Tripp Research springs and metal skirted followers." These have the same followers as the Tripp 8 Round Gen II Cobra Mag.
It sounds like the Ed Brown gun in question only worked with Brown mags.
FWIW, I haven't had any problems with mags in my Ed Brown that don't also cause problems in my 1* and my CQB. All of my problem mags have been Wilson 47Ds.
I had trouble with my 47Ds when I first started shooting my Special Forces. After 200 or so rounds the bearing surface between the slide stop and plunger tube detent smoothed out and the slide now locks back on 47Ds, Colt GI mags, Ed Brown mags, and the new Wilson ETM mags.
As a point of reference, I run Wilson 47D's in an Ed Brown Kobra with no issues.
Where are you at round count wise with the SF and Yost?
That's a good question, and frankly I have no idea. I gave up on round counting for any of my guns shortly after I wrote the original posts. I just lost interest in it. I know that some people have a round-count maintenance schedule for their guns but I don't anymore.
