I want to get a 10mm RIA 1911 double stack and I was doing the research on the details of each of these models... 52000 vs 52009. RIA's website doesn't list details of the 52009 (5" version). Has it been discontinued? I'm leaning towards the 6" version (52000) since this is going to be a range gun... mostly. Opinions, suggestions, and comments, please?
