The best grip we've tried for Nintendo Switch 2 is on sale at Best Buy as a last-minute holiday deal. Dbrand's Killswitch Grip Case Travel Bundle is discounted to $72 (was $80). Though it's pricier than many Switch 2 grips available on Amazon, the Killswitch has superb ergonomics, a clever dock adapter that works seamlessly, and a three-piece design that lets you use the grips for mouse mode and single Joy-Con 2 motion controls.
