Am I reading the 2005 rule book right when it says you cannot use a pistol with a barrel in it that was not designed for it from the factory. Does this mean any conversion barrels at all? Is there an update to this rule? I was thinking of using a 9mm conversion in my G22 but is this is not something that I can use I guess you have to buy a whole new pistol. Just wondering, Bob

Under strict IDPA rules, you may not use a caliber conversion barrel in a Glock because a Glock 22 is just and only a .40 from the factory, unlike other makes that use the same model number for different calibers. A 9mm conversion barrel constitutes a "bull barrel" in the .40 slide.
BUT: NASA is not an affiliated club, so if that is the only place you will shoot, we don't care if you buy big and shoot small. An affiliated club would not allow it... if a Safety Officer happened to notice. A sanctioned state level match would likely catch it at the chronograph station when your model number and caliber did not match.
