So I wanna start a new Character to use mainly pistols(.45 auto, weathered 10mm, maria) and rifles(service rifle, survivalist rifle, assault carbine).
I normally go sniper and most of my perks are non combat. I'm looking for advice on everything(perks, traits, gear, SPECIAL, Skills). I'm in the mood for something different I almost always play the same character. I would really appreciate any help on this.

You don't need a build for guns character. Just boost Guns to 100 and anything else is extra.
For a shocktrooper, however, I recommend high endurance.

With that weapon list I'd say get Grunt for sure.

High agility, decent STR (look up the weapons you plan to use) and Grunt and/or Cowboy perk.
Hand Loaded ammo is also a good perk.
All other guns perks increase VATS accuracy, which you may or may not want, depending on your playstyle.
