I was looking at other YouTube video's of 3 gunning, since I've never done it, and I noticed that nobody seemed to be running a detachable box mag fed shotgun. Is is because they aren't allowed, or just not used?
It was the shotgun section that seemed slower to me as well. Her pistol shooting was pretty dang good and the rifle was pretty dang close. Maybe I have unreasonable expectations of shotgun running. It's not my forte at all.
Looked into it, since I want to play 3-gun myself, and you can use Saigas but they're pretty much unlimited or outlaw division, from what I read. There are also often reliability issues, and fixing or warding those off is $$$. Get a standard pump or semi-auto, save money, and be able to trust your gun for a lot less. Sounds like a win to me. Typical loadout seems to be a 9mm high-cap pistol, a .223 AR, and a semi-auto 12-gauge (lots of people using a Mossberg 930, apparently)
I plan to get a Mossberg 590, myself, which I'll be able to use for any division (including Heavy Metal, which sounds like fun - mag-fed .308 rifle, mag-fed .45ACP pistol, pump-action 12-gauge shotgun). Got the AR, and want a Springfield XDm Competition in 9mm. Currently I only have a 1911 in .45, which is what I'll start with. Should be fun.
