So I am going back to the 4th gen G22 for work and carry so I dug out my G22 mags last night and noticed like 4 older LE mags I had ordered from OMB are broken at the top in the front? The plastic is pulled out away from the metal, I haven't used them yet to check functionality but they sure don't drop free you have to pull them out. Is this common? I haven't had any do this before. I got them from the "used mags" on omb last week so I doubt they would replace them.
