The angle on the grip: try the following exercise - look up, close your eyes, lift your hand and point at some imaginary object right in front of you.Now open your eyes. The probability of finding that your hand is lying at an angle is almost 100%. That rotational angle that our hands naturally follows from the physiology of our musculature is the angle we have put in the grip of our GRS stocks. This will increase your relaxation at a fundamental point of your shooting: your hand.
