Funny that so many people have magazine problems... I've owned six .45s and at least 20 .38 Supers and 9mms and have never had a magazine problem except for magazines that had the extra round built in by modifying the follower and not extending the base pad.
Colt OEM magazines are made by MetalForm and I believe Checkmate. The MetalForm made magazines can be identified by a M in the upper right corner of the baseplate. If it has a S in the lower right corner it is stainless. I've never had a Metalform or OEM Colt marked magazine cause feeding problems. I've also got at lest a dozen old military contract magazines that have caused no issues...
A lot of feeding issues can be traced to improperly tuned extractors that don't have the correct bevel to allow the case rim to slide smoothly under the extractor when the slide starts forward...
