Custom Weapons in a game mode

Im trying to make a game mode and im having trouble getting the player to start with a custom weapon. specifically kermite’s M92 from the pistol pack. I dont know where to find the name of the weapon that the engine uses. I have looked in the LUA to find the name with no luck. Where can i find it to add it to the gamemode? Do I have to include something?

The folder name that contains all the weapons data (being init.lua,cl_init.lua,and shared.lua) would be your weapon name (at least in lua) for example if i wanted to have the player start out with a pistol and the folder that contained that data was called “weapon_pistol” i would do this.
of course you would add that to the player spawn function but im sure you get the point.
