All I can say is, "wow." It's been a while since I had any tactical practice, although I've been carrying for 20+ years and have LEO & Military family members. I took a few defensive courses back in the 90's, and have been putting a lot of hole in paper over the years. I was hesitant to try IDPA, as I figured I was a good marksman and feel it would be a safe environment to be around a lot of folks drawing, moving, and firing.
Well, I was wrong, and I'm totally hooked on IDPA now. Not only was it a tremendous amount of fun, it was safe and I learned so much. Like, learning that I'm not as good as I thought I was ;-) Punching holes in paper at 10 and 25 yds and getting tight groups is OK, but when you haveto move, retreat, use cover, and the adrenalin is pumping it's a whole new world. If you haven't tried it, I highly suggest you seek out a local match. $15 and 150 rounds of ammo were well worth it, can't wait for my next match. The Safety Officers were outstanding, and took time at each stage to critique and coach my performance.
