In some incidences the 6 point inside the grip panels may need to be trimmed to get the panels to fit properly. This can easily be done with a file. Simply remove the material from the corner or side in the direction you want to move the grip. Take one or two passes with the file and check the panel to the frame and the alignment of the screw hole. It should only take a pass or two to get the panels to line up. Check the other side before removing any material; it may not need any material removed. Then snug up the grip screw and check the function of the firearm prior to loading and firing.
