I was messing around with my father in-law's g30 and I just noticed that the slide does not stay open when the last round is ejected/ empty magazine. Is this normal? Unless you are counting your shots, you wouldn't know that you're out!!! click! I checked the slide lever and it is installed correctly. I noticed that the lever comes up slightly but not even half way to locking position.It's not a magazine problem either, both mags do the same thing.
