I have one huge problem with Glocks, say the G30. I simply CANNOT depress the mag release. I have to use my off-hand to press it. I think that is unacceptable. I wish the Glock mag release wasn’t so difficult to depress. That is my only complaint.
You have a bad firearm.....send it back !
That is not normal at all .
Stay safe !
I have to concur with Squantos. My G17 mags come out cleanly with a push of the thumb. You may want to have it looked at, as that is not normal behavior. Good luck!!
