Top level shooters say that a correct grip hold is half way to a successful shooting. That is correct!
All that mentioned above is with the purpose of providing a hold of the pistol with minimum arc of movement in the middle of the aiming area, with consistency and the minimum use of energy. Despite all these requirements being fulfilled, the final and most precious part of the shooting position belongs to the correct placement of the right hand on the correctly built pistol grip.
The position of the right hand has a major role in correct holding of the weapon. There are three important points on the hand and on the grip that must be considered:
• space between thumb and index (trigger) finger – behind barrel and under the rear sight.
• down part of the hand, next to the wrist ankle (art. ulnaris) – upper (supportive) part of the grip.
• upper part of the middle joint of the middle finger on which is laying grip’s part under the trigger mechanism.
When these three points of the hand are correctly placed on the appointed places on the grip, they will form a triangle.
The best place to hold the gun is at its construction COG (left photo – red dot), but for obvious reasons it is not possible. Therefore, we are trying to get as closer as it is physically possible to this mark by supporting it at point two (blue dot), as a centre of the triangle hold.
This technique of gripping results in the use of the law of the lever. Such approach will give possibility to hold the gun with minimum muscle activity, saving energy and minimizing arc of the movement of the pistol.
When, applying pressure on the grip, it is essentiality important in doing so that there are no lateral forces. All pressure forces must be done in parallel with barrel and in 90° axis of the barrel.
Three fingers, little, ring and middle finger, are banded around the grip with nice, smooth tension which is always the same and pressure on the grip is with the middle phalanges of the fingers. Any other deployment of the forces will result with lateral deviations of the axis of the barrel.
The most important finger of the hand, trigger finger, must be free of any contact with the grip. Only in this way are there optimal conditions for the correct activity of the trigger finger and correct triggering action. If this is not the case i.e., trigger finger has contact with the grip, every attempt of triggering will result in movement of the pistol from the optimal sighting point, and precision will be decreased.
Last, phalanges of the thumb – little – middle – ring finger, can have contact with the grip, but without any significant pressure.
Finally, here is the photo showing points of pressure and transfer points of the forces allowed during griping technique.
