I just purchased a new Glock 43 in November. My problem is with an unloaded magazine in the gun if I pull the slide all the way to open locked position I can't close slide. It won't release by pushing the slide stop lever or pulling back a little more on the slide and releasing. The only way that the slide will close is if I take out the unloaded magazine and pull back on it and let go of it. The slide stop lever doesn't close the slide with magazine in or out.
