Saturday, my wife purchased a ruger 22/45 LITE, the blue one. We went to our camp and shot it Saturday afternoon. My question is, the slide release, when the slide is locked back and a loaded magazine in. pulling on the slide will not release it? we had to use the slide release button everytime, is this normal on the 22/45? I have a few rugers, but this is the 1st 22/45 I have any experience with.
