In my "limited" experience...
Pro-Mag = Weak Springs and light metal tubes, they may or may not work reliably....
Mec-Gar = Fit and Finish seems short of OEM and better brands, but have strong springs and so far seem to work reliably...
Wilson Combat = Good Quality, Good Springs, Work Reliably
OEM = Seem the highest quality and strong springs, always work reliably
AFA Springfield Armory, their OEM mags are always available on their website and reasonably priced, usually only a few bucks more than aftermarket, cheaper than Wilson Combat....
I've never used a Springfield 1911 Magazine though, so I can't really comment on their magazines for 1911's...
