Has anyone had trouble with slide not locking back with the 10 round magazine? I did some checking and there is a good 1/8" play after the magazine locks in place. If I push up on the mag, the slide locks back. If I do nothing, slide will not lock back. The magazine has almost no use on it, other than being loaded with 10 rounds. I talked to Ruger about it and I have to send it in. I have to qualify with it next week so got to use it for that then send it in.
