I think Jim hit the nail on the head. Get out and do it with a gun you shoot reasonably well.
I have a G21 that I shot my first match with. I can shoot pretty fast/accurate, but IDPA is so much more. Moving fast is really about taking the right steps. Before you shoot, think about how you will shoot, how you will use cover and how you will movee from position to position.
It might actually improve your score to shoot methodically and move slow.
