I'm not sure what to call the method/stance I use, but it's the one put forth by HK Int'l TD. Body is fairly square to target, right foot back slightly, elbows tucked in tight, shoulders over the knees in an aggressive forward lean/crouch, and stock mounted just medial to the pocket, right in the middle of the pectoral. This position offers a high degree of stability, and works well in body armor. Unfortunately, for a guy with short arms, it is a horrible position for a pump shotgun.
