The problem with the chargers with large handles is that they either get caught up on gear or they jab you when the rifle is slung.
I like the radian handles for most of my rigs, but on the one I carry the most, I use a daniel defense. It doesn't get caught up or jab you like most but stills gives good purchase for one finger operation. If I had it to do over again, I'd be running daniels on all of my rifles, but I already had the radians when I discovered the daniel defense.
I think it's called the grip n rip or something like that.
