But what about releasing the crane with your left hand, pushing it out with the same grip, and utilizing your more skilled dominant Right hand to manipulate the speed loader? Yes you shall need to regrip your revolver prior to firing the next six rounds, but which is actually fractions of a second faster?
Its a wash. The answer is whichever method you practice with is the one thats faster. Im a right hand loader guy. I want to have control of the cylinder with my support hand when loading. Works great when running and reloading. What works good during shooting static at the range might not work so well when movement is involved.
