The only issue with metal mags is they all look alike and half of the makers are junk. Three main makers of us milspec mags are out there only two are any good.
If you don't know the diff in metal mags stick with pmags.
This is the conclusion I came to after asking several weeks ago. I simply don't know enough about the metal ones and what exactly I'm looking at to make an informed decision. Last weekend I went to a small gun show and only one guy had any mags. They were beat up and looked identical. One stack was $20 a piece, and the other were $35! To say the least I passed.
