Destroys mags - Anarchy Outdoors Glock Extended Magazine Release

It’s easy enough to install and it’s aesthetically pleasing. However, within 10 to 20 rounds, it broke the ledge in the notch on the mag, eliminating the ability to use that mag ever again. The notch in the mag that sits on the mag catch cut the top ledge out in that notch, and therefore the mag release would not hold a mag in the gun anymore. It would drop out the moment you slid it in. I noticed on two other mags that it started to do the same thing, but not to the point of breaking that ledge. I only shot 100 rounds total through the pistol using three different mags, one completely broken and two started to show wear as if the catch was cutting into them. I don’t know why this would occur, but I would not recommend this for that reason.
