To change your weapon in Call of Duty during a game, you can use the quick-switch feature by pressing the designated button for your secondary weapon (usually the "2" key on PC or the "Y" button on Xbox and "Triangle" on PlayStation). If you want to select a different primary weapon, you must either pick up another weapon from the ground or switch to your loadout using a loadout drop, if available. Additionally, you can customize your loadouts in the game's menu between matches.
It was your weapon!
There is no best weapon in Call of Duty, it's all about your personal preference, if you like a weapon use it. If you don't like it, don't use it:)
The only Call of Duty game to have a weapon camouflage labeled snow is Call of Duty: Modern Warfare 3. Other games had snow type camouflage but called it by a different name.
