I used to keep a M1 Carbine with a 30 round magazine handy when I was a bachelor. Later, I kept a Remington 870 12 gauge handy, in its simple bird hunting configuration. Now I keep an Astra A-75 in either 9mm or .40 S&W handy, after taking numerous NRA hangun training courses including Defensive Pistol, improving my handgun proficiency. Next month I'm signed up for NRA Defensive Shotgun training, it'll be interesting to see what I learn from that.
Where do I live? Currently, in the 7th largest city in the USA, with criminal activity linked primarily to drug cartels and MS-13 rampant. There were 2 incidents involving gunplay (multiple shots / handun mag dump at a residence from a vehilce on the street) already in the 2 years we've lived here, in the toniest neighborhood I've ever lived in.
