Can you chop the grip of a 31 (Full size) so it will take the 33 mags? Can it affect reliability because of weight loss on grip? Has anyone done this or are there companies that will do this mod? I have both guns and I thought it would be nice to have the sight radius of the bigger one with concealability of the small one. Also does anyone have any pics? I don't really like the textured look that robar does to thiers, is it possible just to chop the grip and round the edges leaving it looking like a stock 33 grip frame?
