My major down fall in IDPA matches is rapid fire at pop up and swing targets. Seems I always get a fail to neutralize at those stations. I do have access at my gun club to practice these but, it would be a major pain to constantly keep setting them up by myself. Another thing that was giving me fits was shooting weak hand. Then I moved the sights farther toward my dominate eye and vastly improved my accuracy but still very slow compared to strong side.
I normally shoot CDP class (.45 cal) with a 1911 Kimber but next time I'm going to use my baby G-26, as I carry it on occasion. I always shoot what I carry the most. Next month we have a night IDPA match, my first one, should be interesting!
