I exclusively use g300s that is notorious for developing double click. Was also fed up with warranty replacement every 6 months so, searched a bit on Google for mouse switched and replaced the crappy omron switches that Logitech uses on their mice with Huano Blue shell White dot Micro Switch and been working great since an year. Might recommend you to have the switches replaced instead of replacing the mouse.
There are better switches than the one and I suggest you to do a bit of research on what type of switch you need(No of clicks, sound, effort required for click). I selected blue switch white dot as the quantity of switches I was getting did overcome with the price of quality ones.
