When a handgun is being fired, the hammer strikes the bullet casing which is higher than the handgrip. This results in a slight torque which causes the barrel of the weapon to point downwards, very slightly off target, before the powder ignites.
Today’s invention is a way to overcome this source of inaccuracy.
Here the trigger (red) is located above the barrel (green), so that when the hammer (blue) strikes, its action is directly in line with the centre of gripping forces, lessening the above effect.
