interesting article in medscape from 2013 which discusses incapacitation of someone due to a a firearm wound:
quote: Thanks to Hollywood portrayals of gunfights and firearm wounds, many people are of the erroneous opinion that a single firearm wound will cause immediate incapacitation in all cases and that a bullet will knock a victim to the ground, against a wall, or through a window.
None of this, of course, is true.
Victims often sustain firearm wounds, sometimes multiple wounds,
without becoming incapacitated.[35] Only a significant central nervous system injury or a wound that compromises the stability and integrity of the supporting skeleton can generally be expected to cause a victim to stop and fall to the ground immediately. The kinetic energy of a bullet striking a target may appear fairly high (in the range of 500-1000 ft-lb of energy for a typical handgun cartridge), but because the bullet mass is so small, the actual momentum transferred to the target is quite small.
As such, bullets do not throw or knock victims about.[35] Spitz WU, Petty CS, Fisher RS. Physical activity until collapse following fatal injury by firearms and sharp pointed weapons. J Forensic Sci. 1961;6:290-300.
Conversely, typical media presentations show firearm victims being rather innocuously wounded in locations such as the extremities or shoulder by a well-placed shot from a hero who "only wanted to 'wing' him, not kill him." I
n fact, wounds of the extremities are often fatal and/or maiming injuries, and in a gunfight, such precise shot placement on a moving target is highly improbable. unquote

article covered quite a bit of forensic discussion about gunshot wounds.
