SLAB: CNC Machined 6061 billet aluminum with a beautiful BLACK hard coat Anodized finish.  

MAG: High strength injection molded polymer MAG designed to engage your pistol's magazine catch.  The base is raised for clearance of the magazine catch on the bottom of the grip, with enough room to disengage for removal from the stand.  The pistol snaps securely to the stand so both pieces can be handled as one unit.  
Hydrophoboc polymer will not wick moisture and hold it inside your gun like wood does.
Self-Lubricating polymer will not scuff the finish inside your grip frame.
