Now there is no pistol 2, and it has it's own name, it seems odd to have a pistol 1. Just change the name to standard pistol, or 9mm pistol. The rifleman HMG isn't a HMG either, it's a light machine gun. With SMGs 1 and 2, give them more 'real' names, even if it's the light and heavy SMGs, or maybe make up calibres (0.22 and 0.35?). or give SMG 2 a name, like 'Uzi' or something random, like 'Scorpion' for instance.
I was mostly pointing out that it makes no sense to have 1 pistol with a number and 1 with a name, and that the HMG is just wrong.
Couldn't you just get some of the weapon names from the Empires wiki? http://wiki.empiresmod.com/index.php?title=Weapons_of_the_Brenodi_Empire http://wiki.empiresmod.com/index.php?title=Weapons_of_the_Northern_Faction
Doesn't sound like a great name though... Probably be better to let you name the thing rather than have it named after you.
