I shot in an IDPA match for the 1st time this weekend. I used my Walther P99 9mm. I did ok for my 1st time. I had always thought I was a terrible shot but I knocked down each of the steel targets with one shot and hit the paper targets with pretty good accuracy. I was slow but I was concentrating on safety it being my 1st time and all. It was a real confidence booster. Most of the other shooters had .45's and maybe .40's. Does anyone else use their P99 9mm in that type of shooting? Let me add- It was a blast! I can't wait to do it again.
