What the grip is missing! - AIM Sports Inc Tactical Vertical Grips w/ Side Rails

The concept of the Picatinny rails is great, but the wrest is lacking. The grip diameter is to small. The battery shaped side piece has sharp edges that make it uncomfortable to hold, and the grip needs to be ergonomic with finger grooves like the Command Arms Ergonomic Vertical Polymer Grip. If you put all these missing items into the grip you would really have something special, and in my opinion it would be a 5 star product instead of a 3.
