Hah!
Even in a USPSA Production/Single Stack allowed position, it would be tough without a dropped holster. It's not something IDPA is ever going to change (I would be happy to be wrong). If the shoulder gets better, I'll be back. Until then, I'll stick with the other games that allow more freedom!
