I love the discipline and competitive nature of shooting. I enjoy handgun and carbine/rifle combat shooting. The IDPA (International Defensive Pistol Association)
www.idpa.com has a really good setup that just about anyone can compete in for handgun. The local club for it also runs carbine matches where I am. The social gathering and being around other shooters is great along with showing off your latest acquisition and sharing guns, it's great fun.
