Function of physiological changes
The physiological changes that occur during the fight or flight response are activated in order to give the body increased strength and speed in anticipation of fighting or running. Some of the specific physiological changes and their functions include:[14][15]
Increased blood flow to the muscles activated by diverting blood flow from other parts of the body.
Increased blood pressure, heart rate, blood sugars, and fats in order to supply the body with extra energy.
The blood clotting function of the body speeds up in order to prevent excessive blood loss in the event of an injury sustained during the response.
Increased muscle tension in order to provide the body with extra speed and strength.
Emotional components
Emotion regulation
See also: Emotional self-regulation
In the context of the fight or flight response, emotional regulation is used proactively to avoid threats of stress or to control the level of emotional arousal.[16][17]
Emotional reactivity
During the reaction, the intensity of emotion that is brought on by the stimulus will also determine the nature and intensity of the behavioral response.[18] Individuals with higher levels of emotional reactivity may be prone to anxiety and aggression, which illustrates the implications of appropriate emotional reaction in the fight or flight response.[19][20]
Cognitive components
Content specificity
The specific components of cognitions in the fight or flight response seem to be largely negative. These negative cognitions may be characterized by: attention to negative stimuli, the perception of ambiguous situations as negative, and the recurrence of recalling negative words.[21] There also may be specific negative thoughts associated with emotions commonly seen in the reaction.[22]
Perception of control
Perceived control relates to an individual's thoughts about control over situations and events.[23] Perceived control should be differentiated from actual control because an individual's beliefs about their abilities may not reflect their actual abilities. Therefore, overestimation or underestimation of perceived control can lead to anxiety and aggression.[24]
Social information processing
See also: Social information processing (cognition)
The social information processing model proposes a variety of factors that determine behavior in the context of social situations and preexisting thoughts.[25] The attribution of hostility, especially in ambiguous situations, seems to be one of the most important cognitive factors associated with the fight or flight response because of its implications towards aggression.[26]

I'm in the UK and do not have much direct involvement with guns of any sort these days but i agree if you are drawing/using a firearm its to kill...guns are not something you use unless there is no alternative and you always shoot to kill if you are at the point of using a firearm.
Guns are not to injure then capture they are to stop an immediate threat FULL STOP.

Please be aware I'm UK and shooting the breeze,
Burr's arguing that a .22 has benefits if you're woken up at night, in the dark and don't want to be deafened and blinded by the discharge of a higher calibre weapon. It's stand up and played for laughs.
