So while at the IDPA match this past weekend I started talking to a guy about 3 gun. It sounds really fun and wouldn't mind trying it. What do you guys use when you shoot 3 gun? I want to at least be competitive and want to make sure my equipment matches up. Currently I have a modded sks, a mossberg 500, and a sigma 9 or m&p 40 to use. I am wanting to do an ar 15 build but wont be doing that til I get some side cash.
