I've got 2 E-Lander Mags I received from Midway and I have 6 on order from E-Lander (mid 10xxx order number). One is stamped 10 with no date and one is stamped 11 with no date. Both have the open mag catch slot as opposed to the partially covered mag catch slot seen on the later batches.
They Function, Seat & Drop Free fine in my Bushy (Don't judge I was learning back then...) but not in my Colt 6920. Fully loaded I have to push on a closed bolt with decent force (download 1-2 rounds and this mostly goes away) and 1 of the 2 Mags does not drop free (the one numbered 10). If I shake the Colt some it will drop but that is not "drop free" in my book...
I got these as range/training mags and will use them as such. I haven't taken my Dremel to them yet since I'm hoping keeping them loaded for a week or two might help. Will update when I get my order from The Mako Group (next week or two judging by others ship dates).
