This is my 24-3, 3". The RB combat grips just don't fit my hand, so I looked around until I found a "donor" set of stocks. They were full size Sq Butt, finger groove. I shortened them about a 1/4", sanded off most of the finger grooves, and contoured the butt. They are much slimmer, and actually carry pretty well. Wood is rosewood. I've been happy with them for several years now.
