I just bought my wife a new ez 9. Was gonna get the 380 version but with the 9 we can both use the same ammo....easier and cheaper. The slide lock release button is really stiff and difficult. I know this is normal for a new gun and it should get better with wear but its not so bad with no magazine , with the magazine in however there is a flange inside that pushes down on the little plastic button on the side of the magazine. With a mag inserted , pushing the slide release down to release the slide also pushes down against the spring pressure in the magazine. No wonder its so hard to release the slide lock when a magazine is inserted. With a loaded mag , and compressed spring , the slide release is near impossible to push. That wont get better over time. Thats crazy. Are they all that way or is it a defect ?
