Pierce Grip Modification

I hooked a buddy up with a Springer Loaded last week. It came with Pearce Grip model PG1911-2. He didn't like the added girth with these installed and gave them to me to try.

What I wanted to do to alleviate the added width is to cut off the side panels that go underneath the grip panels. Then, use adhesive to glue the finger grooves on the frontstrap. Has anyone tried this? Is there a better idea?
