Not the best - FAB Defense Grip Position Versatile/Handstop Tactical Support

It is better than nothing but definitely not the best. Pro's are they are cheap, quick to install, look good, light an minimalistic. Con's are they don't give you much room for your hands, they would not install on some rails, the screw is slightly too big so when you tighten them the screw sticks out on the other side an is sharp. Overall better than nothing, they're cheap and a small profile but I would not buy again.
