Hey guys, now, I got MW3 the other day and noticed the aim was click and it toggled it instead of hold, now, for that, I prefer hold so you don't gotta double click and here is my easy tutorial on how to switch it.
Step 1: Boot up your CoD main menu or online. (For this, I'm going to be loading up my Multiplayer)
Step 2: Go to "Options" in the menu.
Step 3: Select "Controls" then "Actions"
Step 4: Now you will see something like "Aim down the sight" and "Hold down the sight"
Step 5: Left click on "Hold Aim down the sight" until you get three "???"'s.
Step 6: Simply right click, and back out to the main menu and you are good to go.
Q. What is the difference between toggle and aim?
A. The difference is, with toggle, it's more harder to control (personally) and you have to keep clicking then re-clicking and so on, but with it being HOLD, you get more of a better edge, you can just right click and hold, once you're done, run, sprint, let go, whatever and it's all easy.
Q. Why didn't you use hide tags?
A. Because I don't like getting credits for tutorials.
