Minor PF vs Major PF
I have an xdm9 and am looking to get into competition (just learning and haven't shot in competition or for that matter haven't shot that much at all) and if I interpret what I have learned so far is that a 9 is in the Minor Pf. Which puts me behind the 8 ball to start with. My question I guess would be do I purchase a 45 to put me in the Major PF and be more competitive? or do I shoot what I have and have a good time and learn more before worrying about PF's? If I do stay with the 9 and get used to shooting it and then in due time want to upgrade to a 45 what about the learning curve of shooting a new gun?
