Not neccesarily, mine will take effort to seat fully loaded with the slide closed, as if doing a tactical reload. I always push mags in hard anyway.
His won't seat at all with that much tension on the rounds pushing up, so I would have it look at.
As for 10 rounds, nah, pass, I like fully loaded mags, and this is AZ, I can do that.

C'mon over across the border, we welcome ALL good gun people, especially Czechs!
