The product looks well made but they missed something- they included two hump style inserts and only one that looks like it might work. Plus there is no real comparison outline of these compaired to eachother. Finally the 1911 style- still looks curved. I don't know how these guys missed the idea that a grip reduction is to remove the hump but they did. Someone needs to make sure they understand that they have a solid idea but need to work more toward a true straight back type grip.
