I have all the equipment I need for 3-gun, but I see more IDPA DMG matches around so I think I will begin going to those as I pay the membership fee, but only do pistol competitions. I have read through the firearm requirements and I am good with those. But I wanted to know: - Can I can use my Safariland ELS gear setup for 3-gun (belt, holster, carriers)? - Would my shotgun need to be plugged or can I run it as is, but only charge it to 5+1? Thank you.
