Today’s module focus on the Physiology of the hands
This module will start off with taking a step back and look at the human physiology of the hands and the separation of the muscles through the gripping portion and the upper forearms. As shown in the video, instruct the individuals to hold the SIRT in the support hand and have their strong hand up in their facial area. At this time, tell the individuals to take their lower three fingers with their index finger extended and grip a rope as if they're trying to grip a thin rope in the middle of their hand. We call this a rope grip but moreover note the contraction of the index finger when they adopt a rope style grip. This is an involuntary contraction because the fingertips are all connected to the same muscle in the upper forearm. Now simply have them adopt what is called a c-clamp grip which I credit to Larry Yatch. C-clamp grip basically pivots the lower three fingers about the main knuckles and brings the lower three fingers slightly rearward very much independent from the index finger. Of course some pressure in the front portion of the grip is advantageous for returning the muzzle down to a consistent location but instead of gripping the sides of the pistols which really does not do much good because we rely on friction on the sides of the pistols it's best just to press the rear part of the second knuckles rearward by way of pivoting the big knuckles. The trigger finger is left isolated to pull the trigger irrespective of the pressure on the front portion of the gun. When individuals adopt a rope style grip and press their fingertips in the side of the gun they generally have to loosen this grip to accommodate trigger mechanics. This makes gripping the gun extremely difficult and a precarious balance like a 60/40 rule or other such rules which can be completely averted if you simply adopt a c-clamp grip. As noted above Mr. Larry Yatch learned this phenomena in teaching at his sealed mindset where he found he could get a wide array of students with various skill levels and abilities to have a proper grip in trigger mechanics very quickly by adopting a c-clamp grip as opposed to a rope grip. By driving a c-clamp grip in the subconscious competent set puts the students on a glide path to be able to isolate their grip from their trigger finger so under stress if they have a more compressed grip their trigger finger will operate independently from their gripping muscles.
As you explain this, have them adopt a c-clamp grip with the SIRT and go strong hand only. They may notice slight movement of the fingertips and the thumbs when they do rapid shots fast, which is totally fine. Dave Sevigny is probably the best shooter in the world and his strong hand thumb moves quite a bit when he's hammering down but because his thumb is high and outside out of the way it doesn't impede his shooting performance or accuracy whatsoever.
Now have them place the support hand on in the manner as described above in Day Two where the base of the thumbs are pressed together and the rear portion and pressed together by the chest and have them adopt a c-clamp grip where perhaps the fingertips are in the palm of their other hand and have them engage basically the same presentation drills as before but encourage them to go fast and observe if they have further isolation of their trigger finger with respect to their gripping fingers. Now instruct them to grip the gun a little bit more aggressively with chest squeeze and c-clamp pressure and see if there's any erosion of their trigger mechanics. As a progression and drill on this, have them grip as hard as they can while pressing the trigger rapidly and relax the grip then see if there's any erosion of their trigger speed and trigger mechanics (by way of looking at the laser dash). For some people, if not most people, you may find that as they grip hard their trigger mechanics (and trigger speed) may not erode or otherwise slow down, but this is their self-exploration and journey to understand the relationship of grip and trigger control and as much as possible isolate these two fundamentals away from each other so a hard grip does not interfere with their trigger mechanics.
