My Ruger MkIII has a lightened trigger and is dead reliable. I'm fairly certain I could put all 10 rounds into a torso-sized target within 3 seconds. Now if that doesn't stop the BG, I'd be much more confident at taking him on hand-to-hand with him suffering from a number of bullet holes, no matter how small. With that being said, I'd never use a .22 as my primary self defense weapon.
