I have been researching the IPSC style shooting and the IDPA style shooting matches and rules over the past several days. I have come to the conclusion that I am more suited for and would enjoy the IDPA matches more. I am going to watch a match this Saturday. I have one question, who carries holsters that meet the IDPA criteria in left handed models? I will be shooting either a Springfield XD 4" or a Kimber 1911 style.
