I'm more inclined to agree with Dennis, if you're looking for an inexpensive piece. What if two shots aren't enough, or maybe, with the stress factor high, they miss their mark? Do you want him to be digging the empties out of an extractor gun before he can reload? I wouldn't want to have to if it were me. The single trigger on a pump would be better for someone not 100% accustomed to double triggers, too, again, in a life threatening situation.
