I'm considering VZ double diamond slim G10 grips. I saw they offer "universal" bushings. Do the universal bushings use standard length screws? Would it be better to buy slim bushings and screws? Are the slim grips actually a benefit for those of us with shorter fingers/smaller hands? The factory grips look good but seem too round in profile. My Remington R1 isn't a primary carry gun but I want it to point better for me.
