A couple of things I came across that may be helpful to other newbies: I had these questions answered by Jeff at steyr us customer service. Awesome customer sercive! I was concerned that the back of my slide did NOT have the loaded chamber indicator. Jeff says that they stopped putting that feature on all the us models except the L series. Also, while the slide is locked open, I was concerned with the firing pin rattling around loose inside the slide. Jeff says that ut s normal. If it's not floating then there's a problem.
