Compared to the G Pro 2.0 version, the 3.0 version switches are upgraded in a few aspects. The first thing is that Gatron upgraded its metal pins to 3-layer strengthened pins. This solves the issue that exists on the 2,0 version which is that the pins are too soft and can easily be bent during installation. When using the G Pro 3.0, you don't have to worry about that anymore. Another upgrade is the factory lube; The 3.0 version's factory lube job is more precise than the 2.0 version, and it is truly a switch that can be used stock.
