Saturday I went back and picked up 3. Fired each from full and no problems with feeding. The only issue was that they are a little tough getting them to seat into the gun.
Nowhere as easy as a metal Russian mag. You have to make sure it’s started in the front and very straight. Not so with the Russian mags.
Thanks for everyone’s input.
