From what I understand, the Army is looking at going to hollow point ammo which should help with 9mm stopping power.
I know they wouldn’t do it but I would like to see them go either Glock 20 or 21. 45 standardized to a “NATO” +p power level with 230 grain hollow points and 12 rounds in the mag or full bore 10mm 180 grain hollow points with 15 in the mag. Both would be marginally better than 9mm in a combat environment.
But,,,, with new hollow point ammo, I think the 9mm will make a fine combat sidearm and I fully expect that is what we will end up with.
I too have a couple of government model 45s, they are works of art and I would use either to protect myself but technology has moved on. There are better options now.
Hollow points are banned in international warfare. Hollow points would be used against US civilian targets.
