I've got 5 like new G19 mags to sell. All of them are Gen4 style tubes that will accommodate the reversible mag release. 2 of them have the cutout on the front of the mag body that will accommodate the short-lived ambidextrous mag release glocks. Only a couple boxes of ammo cycled through them.
I had numbered the mags with a sharpie. The ink wipes off after time with an oily rag.
$25 each shipped. SPF
