Does not seem high to me.
When I carry my P226, I have 48 rounds on my person and another 100 in the BOB in the vehicle that we are driving. Only dif when I carry my .45 is the amount I have on me.
That is for going shopping with the wifey.
An empty weapon is nothing more than a steel rock.
This was two people and they were at the range and had several weapons
From the headline, when they said “carry”, they make it sound like on his person. 45 rounds sounds reasonable with one mag in the weapon and two on a belt.
I recall one article where a soldier was describing combat in Iraq. Can’t have too much ammo. They had magazines stuffed everywhere they could in their vehicles.
