Start the player in a room with three weapons on a table?
EDIT: Otherwise, just do what everyone else said. Put them under the player at the start of the game. You can get rid of the "picked up a weapon" HUD, and the pickup sound so it actually seems like the player starts with them.
If you want the sound and HUD to appear for weapons the player will find later in the game, just assign the pickup sound and HUD to a trigger zone, and then put the weapons inside the trigger area.
