Question, are we trying to keep the game somewhat realistic? It would seem like a better idea to me if we made a smaller list of guns and just made them have the ability to be customized like a barrel mod, better stock, mechanisms in the gun, trigger, and of course different sights.
Also I believe guns should be somewhat...domestic. Most states (Assuming the game is based in the U.S. >.<) ban the ownership of Assault Rifles (Especially AK-47s) and SMGs, or put them under strict permit/license laws. That is not to say they are not existent, just much harder to get than Rifles, Shotguns, and Pistols which usually only require a license or (If your lucky) nothing but the money to get it.
Just my two cents
