On various extreme target pistols and rifles, it is not uncommon to see grips that are molded to the hand of the individual shooter. Consistency is, after all, accuracy.
But an ISSF shooter rarely has to pull his free pistol from the bottom of a pigpile, nor does a Three-Position Smallbore competitor need to acquire a good-enough firing grip on his Anschutz while unassing a burning Humvee. Hence, I question the utility of highly-molded stuff like this.
Although I could be wrong.
