You can now drive-by with Baretta shotgun like TLAD or Fast and Furious 4
But there is no model of sawn-off shotgun because I don't know how I can make wft and wtd file so if someone can make a model for me that can be useful for this mod
Note: Be sure to make backup for weaponinfo.xml, It will not work for multiplayer in patch 1.0.0.4 because patch 5 f*cked up the modding
