Lol....well I can understand wanting to shoot a 1911 in .45, my Kimber is a .45, but the cost savings for shooting a 9mm or .40 is just one consideration for shooting minor. Another is the added capacity. Classic rules (for those that don't know) allow 10 rounds in the mag if you shoot minor but only 8 if you shoot major. So the game becomes do you want the extra points for shooting major or the time saved shooting minor. Some courses of fire, Anywhere there is 9 rounds from one position, severly handicap a major gun. A minor gun can carry on but a major gun will have to do a slide lock reload and depending on the layout possibly have to do a slide lock reload for every reload through a course of fire. 9 round short courses that start unloaded automatically drop anyone shooting a major gun by about 30% (or more) as they will have to reload in the middle of the string where a minor gun won't. Good courses of fire will eliminate this advantage but any stage where you see ports with 8, 8, 8, 8, will give the advantage to the minor gun.
