There was nothing wrong with the KAC/P&S Products one, and to be honest, I prefer the feel of the stubby Mapgul RVG (Rail Vertical Grip), but the Cadex one is affordable, it’s what’s on the issue rifle, and if I ever want to return the rifle to that authentic look, I’ll have it available. The differences between KAC/P&S grip compared to the Cadex one is the KAC grip slides on, does not fold, and can be installed without tools (twist/friction attachment system). The Cadex grip folds, locks firmly in place in the open and closed position, can be mounted straight on to the rail (does not need to be slid on) but requires a flat head to crank it down. That being said, everyone in the CF should have their Gerber so this shouldn’t be a problem.
