Weapon ID List - 1.9.461
Hello there, MPGH! Welcome to a new Weapon ID list for Modern Warfare 3, version 1.9.461. All of these weapon IDs were gained one-by-one using Lovroman's MW3 SP/Survival/Spec Ops tool. (Can't link you to the post yet.) Feedback on these IDs are greatly appreciated, and you may contribute to it down below. 
Note: Any skips in numbers means they are nothing. (0, 1, 2, 3, 15, 16, 18, 19, 20, 21, 68, 70, 71, 72)
Note 2: [Crashes game] indicates that the ID has crashed my game. It may or may not differ upon different maps, I dunno.
