A non-slip grip is essential for fast and accurate shooting.  Everything that can be done to eliminate slippage and help you recover back on target is a major asset to your ability to fire rapid controlled repeat shots.  Checkering of the frontstrap and mainspring housing is a big help, but you still need to be able to grip the pistol tightly side to side too.  Sharply checkered grip panels are the answer and the exotic wood panels we install on our pistols are beautiful as well as functional.  They are CNC machined from exotic Coco Bolo wood or Diamond-Wood (Black/Grey) with full coverage checkering and feature the distinctive Wilson logo.  Here is a premium set of grips at a hardball grip price.
