Hey, all. I'd like to shoot my 1st IDPA match soon. I have my CHL, a USPc, a single mag pouch, good belt/holster. I'd *like* to shoot it as I carry, which is to say I don't use a vest (I'm a jeans and polo shirt kinda guy). Any recommendations on a cover garment? Can anyone recommend a range? How much ammo should I bring? I'm excited to give it a try!
