I plan on buying a dozen "assault rifles" in the next year or so, so I am holding off on my major purchases, since I bought/traded/was gifted about a dozen guns in the last two years. I'm largely broke...
I've been buying ammo, magazines, and body armor, so I am tapped out.
I just treated myself to concealable Safariland body armor. I plan to wear it on a daily basis. Having a gun wouldn't do any good if somebody got a first hit on me and I was too wounded to draw and return fire. Even though there will surely be blunt force trauma pain, hopefully the armor gives me a fighting chance to draw and return fire if they get the drop on me.
Still, the best weapon/defense is, as always, SITUATIONAL AWARENESS! I have avoided/averted/ended several situations, before they began, just through situational awareness. People obviously casing me (or my mother), often late at night in parking lots, who were watching intently and readying to make a move, backing off and leaving because they saw I had locked eyes with them, and was putting my hand under my coat.
Yes, it gets that bad... My mother stands around in a deserted parking lot at 10 pm in a strange area, gabbing with her lady friend, as some lone guy in a car pulls up about 200 feet away and starts watching them, staying put in the middle of the parking lot for 30-90 seconds, until I lock eyes with him and start to reach into my coat, at which time he pulls away and exits the parking lot. I then told my mother a guy was casing her, and she told me I was crazy. Really, the guy pulled up, stopped his car (engine still running) put the passenger window down, and was leaning over to watch her and her lady friend, until he noticed I was observing him as well, and then I was moving my hand under my coat.
