I really like the Browning M1919A4 and the P38.

Right now i really like my fully american loadout consisting of: M1 Garand M1911 frag grenades M1A1 Bazooka and dynamite... why do all the guns start with M1?

Ikr all the USA guns around that time period start with M1. Alot still do and it's not just guns an example is the M1 Abrams tank.
