Any psychological effect for gun size mattering in a defensive situation? Out of the gate here I have to admit to being a total civilian. My seven year Navy experience never put the bad guy directly in front of me. I have frequented mini-marts and malls that have been victim to various crime events so now I always think about my situational awareness and mentally practice retreat and/or tactical involvement. Through the years ( a bunch of years, by the way) I have transitioned numerous handguns in and out of legal CCW and I will also admit to brief periods in my life of not carrying at all. When I cloud my mental preparedness with all the fictional ploys of Hollywood and website tales, my question to you is whether or not there is any effect to diffusing a confrontation if you are the one holding the bigger gun? With caliber and bullet-type being the same, are there any substantial data points to consider where intimidation by holding a full-sized 1911 could outweigh holding a mouse-gun, for example, in the eyes of a bad guy? I am not trying to start any pro/con debate about size matters, but rather obtain true feedback regarding psychological effects with intimidation. Maybe another way to inquire: Do all bad guys start shooting at police when they roll up with badges, blue lights, and shooting proficiency, or do real-life bad guys know enough to give up? (Do I really need to tattoo my brain with an image that I'm probably involved with a defensive shooting situation and not waste precious seconds with debating all the verbal shout-outs halt, freeze, stop, etc.). Thanks so very much.
