Get a cheap Uncle Mikes or similar holster. IDPA may require a specific type concealment holster, IPSC would not. 2 or more open top, concealment type mag holders, a couple extra mags and thats all you need. In either you decide to shoot, or even Steel Challenge it is more of a speed vs time issue. Shoot the gun faster than you can hit and you will miss. And that will cost you. For the time being go to better yourself and do not worry about a score. Have fun and get some trigger time. Go slow and make your shots count. You will notice your speed will increase naturally as you get better and more confident of your abilities. As my master told me before, "Slow down to go fast, Grasshopper". I know I have too much to say on the subject. If you want to shoot, then get on the range, go to every type that you think you might enjoy. Wether it be IPSC, IDPA, Bullseye, or PPC just get out there and get some trigger time. Show up ready to shoot and you will be guided by the guys there. If you forgot something, ask, and surely someone will let you borrow what you need if they have it with them to lend.
