remember FiB. Punk-assCloaker's contractor animation mod?  
theres a reload sound glitch, and i found a silly way to fix which is rename others' contractor sound mod to g22.bnk, and added a lua line to bind another gun's sound effect on glock.  
if u wanna change the gun sound, feel free to open the lua file and change self.g22c.sounds.fire="beretta_fire".
based on FiB. Punk-assCloaker's animation mod and Lfren38's contractor sound mod, i only changed a sound file's name and added a line to fix bugs.
