That story is from a pro gun website - you would think they would include what caliber handgun, HP or RN, weight of bullet, etc. Very vague to indicate the intruder survived a point blank shot to the chest and give no info for people to consider on what could be done differently (if anything). The old 9mm vs 45 debate comes to mind but maybe he shot him with a 22lr round? They did tell us the name of his dog, Daisy, that's important info apparently...
