A method and apparatus counteracts the muzzle lift of a firearm resulting
from recoil, and a firearm has an integral counteracting structure. A
port extends from an inner surface of the firearm barrel bore to an outer
surface of the barrel, forward of the location that the propellant
ignites, to an occluding structure located beneath the grip surface of
the firearm. When the propellant is ignited, and the projectile passes
the relief port, a portion of the propellant gas exits the bore prior to
the muzzle end, travels through the propellant gas relief tube, and
exerts a force on the occluding structure. The force acts downward on the
firearm, counteracting the recoil-induced muzzle lift.
