I've never seen an indoor trap/skeet range. The building would have to be pretty huge for that...
You don't need to be a professional or an expert to enjoy firearms. As long as someone can follow the 4 fundamental rules, anyone can enjoy shooting.
CZ? I've not shot any of the Shadow series, but I have lovingly fondled a few. They are really, really well designed pistols. I like the colors, too. Good taste, there!
While I have extensive firearms training, I have not shot a wide variety, yet. My focus on my own firearms has been nearly entirely practical with one exception.
