There is a small flange along the leading edge of the left grip. It is supposed to drop in place behind the frame. It won't. If I remove the flange to make it fit, there will be no stabilization of the grip on the frame. There is also a small cutout at the bottom of that left grip which has to go around a part of the frame. It's not cut out enough, and the grip sits too high on the pistol. As a result of both of these problems, the screw hole is no where near centered.
I've asked for instructions on how to return them for a refund. No response, so I've filed a preliminary case with PayPal.
Needless to say, I'm quite disappointed; as they really look good. It's too bad they won't fit the pistol.
