Halo CE - 3 gun glitch / no pistol glitch

Go through PoA really fast no stopping / always progressing forward.

If you wait a bit right after 'getting' the pistol from captain keyes the pistol will spawn as invisible in that little hallway thing before the first 3 grunts of the game signified when you get the checkpoint.

If you abuse the fact the pistol spawns when that checkpoint happens you can get 2 weapons then come back to get the checkpoint and when you go to where youd normally get the pistol you add it to your inventory since its probably hardcoded to give it to you no matter what making it so you have 3 guns and can fully switch them out and everything.....[doesnt really matter since theres only 4 guns in the first map anyway lmao]
