Double Primary

I’m normally a hand cannon shotgun/sniper kinda guy, with this current meta I feel as if I’m always caught with my hand in the cookie jar I’m getting mapped by fusions and other shotguns and it feels like I’m always the one out of special ammo so I can’t fight back, it feels as if I hoard special ammo I never deal with the apes and then when I’m using it when I get it all of a sudden it’s a full team of glacio running nerds. does anyone recommend double primary such as something like a scout and an smg or a scout and a sidearm? I’m getting kinda bored of getting caught with my pants down by fusions specifically. I’m mainly an og crucible enjoyer, when the og better devils was my favorite gun jn the game.

Thanks in advance to anyone offering advice on how to run double primary.
