Beretta 90 Two
I'm new to the Beretta line and after purchasing a 90 Two 9mm, I began checking some videos of them on YouTube. I noticed that in some when the slide is racked back, without a clip in it, the slide stays racked back. While in others (and indeed my own gun) the slide returns to the closed and ready position. This isn't a big deal to me but was just wondering why. What's the deal?
