Nope. Both magazines had "Glock" molded in. Two friends of mine picked up Glocks about the same time (within a year); one was a model 22, the other a model 23. Bought from different stores in different cities, but all three had all plastic mags.Then someone switched the magazine for non factory.
I'd take a picture but I took them by Glock years back and they swapped them out for metal lined. I don't think they would do that with aftermarket.
