I just got my LC9 and when releasing the magazine if i don't hold down the magazine release button until about 2-3" down it creates a treacle scrape on my magazine. Has anyone else had this issue? I read of one other person having this problem and they were going to send it back to Ruger... I'd like to avoid that if possible. I field stripped it and it looks like there is a ledge between the magazine chamber and the slide that could possible cause it but how would that relate to the release button staying compressed?
