That’s a pretty handy guide. I recently swapped out my .357 revolver for a 9mm semi (15 round magazine) for carrying in my car because the nature of the threat has change: I am more likely to encounter a mob than a single carjacker these days.
Went shooting yesterday. My host brought 10 different handguns with him for me to try out.
Took a liking to the S&W 22 Semi which my wife will like. I am for th M&P40. One of the guns I fired had a built in laser sighting device. There was a .500 Wyoming, which ripped my thumb apart. Tough love I guess.
