cant you just like rename the two files from your GAME folder in your CA folder from the pistol and ak47 to make it appear as your using a pistol but really shooting out an AK47..??ofcourse your going to be the only one that sees this..
Or you can use MHS to change the value of the weapon it thinks you have, i.e I have a gun that has value 1 so I get the value 1 in mhs and I lock it to 3 wow, my gun is now a rocket launcher? people are saying that I'm using my pistol!
