Try the CAA UPG16 it has FULLY cutomizable front and rear grip pads for the grip itself. From what I hear the rubberized front finger grooves, and rear ones realy lock your hand onto the grip for a perfect tight fit. Bascily its made to be just like what a Springfield XDM pistol has.

I have been wanting one for a LONG time, And I see them alot. But I only want it in the tan color to match my rifles color scheme. Some places have the grip from $30 and Ive seen it as high as $50 before. This grip is 100% able to be fitted to the individuals hand. Rather than us having to fit to the pre set grip sizes.
