GP 100 Grip sizes

[sox]

I am confused. Are there actually two different grip sizes available for the GP 100? Is this simply the grips that chage from larger to smaller or is it in fact the grip frames which are different? Also, are they interchangeable with the sp 101? Thanks for your help.

GP 100 grips

Yes there are two different sizes. Full size come on the Adjustable sight versions. Compact come on the fixed sight versions. "Lett Grips" started calling them Square butt and round butt to confuse then with S&W. They are *not* interchangeable with the SP101 series.
The compact grips have a little more swell in the inserts than the full size.
