This spray and pray stuff is awesome! 145 rounds might not be enough for this fella.
Based on the type of shooting and the number of hits, I'm not sure how this qualifies as "spray and pray"?
I did.

"Now he goes to work carrying 145 handgun rounds, all 9mm."
The .45 didn't work so he dropped down to 9mm for his primary gun so he can carry more ammunition.
Here's a guy that's always thinking.
Current data with modern defensive handgun ammo shows that the wounding capacity between 9mm, .40S&W and .45ACP would fall within the statistical margin of error. That, coupled with the normal accuracy increase with 9mm over the other two could be a deciding factor.
