Most all the forend grips are rounded where they come in contact with the frame this is to clear the little bump out on the G2 frame they also look like a Encore grip only a little smaller, on the butt grip the angle is different so that wound would have to be tried on frame or make you a guage to check the angle. I have never seen a grip set for g2 that had any checkering, but there are a lot of older style out there with no checkering. You can also measure the width on the grips and check what you find as there is about 1/6 or more difference from old to g2. maybe this will help some.
