The gear list will be a bit different for this match because it is two gun instead of a standard IDPA matach. Normally, you will need a strong side holster, worn just behind the hip. I recommend one that has a reinforced mouth or is kydex. You will be drawing from the holster and reholsterering and you don't want a holster that collapses on you and makes reholstering difficult. Typically you will need three total mags and either a double mage pouch or two singe mag pouches. The mag pouches are worn behind the weak side hip. I recommend bringing at least 100 rounds. Finally you should have a cover garment. Some times a jacket or sweater will do. I typically can conceal my rig with an untucked t-shirt. Ear and eye protection are required as well.
For this shoot, your rifle or carbine should have a sling as we typically do rifle to pistol transitions. A case for your rifle (soft or hard ) will allow you to safely transport your rifle to and from the firing line, so that is recommended. At least two magazines for your rifle, and mag holder would be a good idea. The match directed has indicated that we will need about 150 rounds for the match. We shoot steel targets at times so no armor piercing rounds please.
I do have a kydex IWB holster, would this be good or does it need to be OWB? I don't carry appendix or small of back.
