Greetings. I'm new to Glocks. I bought a brand new G36 and ordered some extra factory Glock magazines. I noticed a small piece of plastic loose on the front, top of the mag just under the area where the bullet head sits. It was not bonded well to the steel underneath and was peeling off. The plastic was seperating from the steel insert and I had to cut it off (about 1/8" of plastic). The mags work fine but I was wondering if this is normal? I have seven mags and 3 of them have this issue. I love the pistol. Thanks.
