I am considering buying a 9mm 1911 to use in ESP for IDPA. I want to have a spare gun in the range bag in case I have a failure during a match. Does it have to be exactly the same as the one I started the match with? For example, if I use an STI Trojan 5.0 9mm and it breaks, can I pull a Kimber Tactical Pro II 9mm or a Para LTC 9mm out of the range bag and finish the match or would this be against the rules since the original gun is a 5" 1911 and the other guns are 4" 1911's? I would think logically that as long as they were both 1911 pattern guns in the same caliber and the same capacity and both legal for the division you are competing in, it shouldn't matter, but I want to make sure. I just hate to spend the money on two identical guns if I can get a little variety and still use it as a backup.
