Thanks for the advice. I am using all ruger 20 and 30 rd mags. They all drop free if i just hold the the mag release down and let them fall. If I try to remove them by pressing the mag release while holding the mag with the same hand to facilitate removing the mag without letting it free fall to the ground, they will not remove. This is the strangest thing. I am sure I am doing something wrong but what. When I press the mag release with my thumb while holding the mag it will release and pivit forward but I cannot withdraw it. If I use both hands and hold the mag release down the entire time, the mag will pivit forward and then I can remove it. Is this normal?
