The screw on my 17-3 Magna grip is 1.165" from bottom of screw head to end. 1.235" total length.
I think the magna grips are thicker than what have. But thats a start. Thanks for the help.[/QUOTE
Can you post photos of the grips you have?

It sounds like you have the wrong length screw.
Suggest you put a WTB add in classified section.
The gun would have originally shipped with the grips as shown.
