I have a Speed P8 which comes with the Biologic Ergo gripps. They are manufactured
asymmetricly (different sizes) for the P8 due to the grip shift. The larger on the left
and the smaller one on the right.

I replaced the gripshift with a rapidfire so I will need the same size grip on both sides.

So...has anyone out there removed their Biologic grips and have them collecting dust?
