I am going by my personal observations having shot a Level 2 ballistic vest. It certainly is not the be all/end all round or caliber by any means. But for a self-defense pocket gun with a < 3" barrel & round I won't expect to be shooting through engine blocks or even at fleeing cars anyway. The compromise between a common feeding issue in this caliber versus acceptable stopping power is why I made my choice. I guess I will take my chances that if i ever have to use it it will be in one of majority of the instances were it is close quarters person on person for CCW-type self defense occurrences. Or I will try to conceal the 7.62. Luckily I am big and fatter than I should be if I go that route.
