I shot the new G23 as a .40 at an IDPA meet yesterday, ESP. SWEET! I don't shoot IDPA for competition. I do it just to see what errors I am likely to make in a shooting situation. I am amazed at the mistakes I make. At this meet, I gave myself a blood blister on my right hand whamming a mag into place. Then I immediately had an FTF because the mag was not fully seated. That would have been a lot of fun in a real gun fight. I've found another thing to train around at every IDPA event I've participated in. I can tell you it is true that your training takes over in a situation, even against cardboard targets.
