re: Veterans: How much use does a military pistol actually get in deployment?

A deployment of mine was just watching third country nationals and local nationals that came on the base to do jobs fill sandbags, help build new long term shelters etc.

In those situations we carried M-16 and M-9. It was important for us though as we are in the middle of sleeping quarters. If we had to use our weapons M-9 having less velocity is better than M-16 considering what's on the other side of our targets
