Grip
The majority of IPSC competitions are freestyle, which allows the competitor to use a two handed grip on the firearm. The strong hand will grip the firearm as high as possible. The barrel, bones of the wrist, and your forearm should be inline. The three gripping fingers should apply uniform pressure on the front strap of the pistol. The pressure applied by the three fingers on the front strap should be resisted by equal pressure from the palm of the hand applied to the backstrap. There should be no lateral pressure applied to the firearm. If the pressure applied is not uniform, it can affect the accuracy of your shooting.
If the competitor’s hands are large enough, it is strongly recommend that the thumb of the strong hand rest on top of the safety. The thumb should still remain straight. The safety can then act as a type of thumb rest. This technique will give you better steering control of the firearm. The supporting hand wraps around the strong hand, with the fingers wrapping over the fingers, parallel to each other.
When shooting with a two handed grip, the supporting hand applies the pressure in the grip and the strong hand applies less pressure in order to maintain dexterity. The grip on the pistol should be tight enough to hold the firearm securely but not so tight that it causes the competitor’s hands to shake.
