Aftermarket grips for the G34 give you texture that holds consistently across a match stage, geometry matched to your palm, and a thumb shelf for fixed lateral control on every draw. The G34 shares its frame with the G17 and accepts the same grips. As a dedicated Production division competition gun, the G34 benefits from aftermarket grips in exactly the way the G17 does -- and the grip is one of the highest-leverage modifications available within Production rules.
