First Samco G27 pistol grip with locking storage compartment which holds spare parts/batteries. This thing is a combined improvement over the the Ergo Grip and the Tango Down battlegrip, is VERY comfortable and provides excellent finger placement on the trigger while allowing for a high firm weld of the hand to the grip.
Sells for $22, I'm only asking $15 +$3 shipping. Brand new in the box never used.
