I started shooting IDPA last year, and love it. I have a knock-off match at a local range tonight, so last night I was practicing, and realized I had been dropping the slide on my XDm on an empty chamber when showing empty to the RO at the end of a stage. I've read all the pros and cons about doing this, and I try not to whenever I'm at the range practicing. But when finishing a stage and showing the RO the firearm is clear before holstering, I realized I had been doing just that. I will start easing the slide closed with my off hand. Just wondered how many others do it at a match, but not when regularly practicing?
