I suggest a quality .22 revolver. A hit with a .22 is better, it has been said, tham a loud miss with a .45
I think that might be it. Fellas always try to talk me out of a 22 whenever I look at one. What good are bigger bullets when I can't manage the heavier gun well enough to aim? I could just work on getting more shots off with a lighter gun.
When I was on the job I knew a thug from the King Towers in Harlem. His street name was Champ. He walked (WALKED) into the ER at Harlem Hospital with seven (SEVEN) .22 slugs in him......After he stabbed the shooter to death.
