Having shot primarily SS for the last year and a half, I will tell you major vs minor is very match dependent. There are matches like the Single Stack Classic and Battle in the Bluegrass that will usually favor major, but I have found that quite a few area and sectional matches you would be better off with the extra 2 rounds. Now of course that also depends on your accuracy, but if I can save a reload on about half of the stages shooting minor, that's the route I will go. I actually won the WI Sectional this year shooting minor SS, and it proved to be the best choice for that match. Also most of the local matches around me favor minor most of the time. Again it is very match dependent. If nothing else, a 9mm 1911 is fun as heck to shoot, and I use it a lot for cheaper practice. Hope that helps
