I am wondering if it is affordable and doable : 
to install a bisley grip frame on a model 83; 
or 
to round butt the FA 83... 
and if round butting it ... can I get a little larger (longer ) grip installed covering the bottom strap to make it a little longer... 
I am getting a permanent bruise on the palm of my left hand even with the junction of my ring finger and little finger..
that would take care of the problem... I never tried a round butt but the old bisley does not do that cause it is longer. 
I would not care if FA did it or some custom smith did the deed.
